| Accounting Policies [Abstract] | |||
| Basis of Presentation |
The accompanying interim unaudited condensed financial statements and related disclosures are unaudited and have been prepared in accordance with U.S. generally accepted accounting principles (GAAP) for interim financial information and the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all the information and footnotes required by GAAP for complete financial statements and should be read in conjunction with the Company’s financial statements and related footnotes for the year ended December 31, 2016 included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016, which was filed with the Securities and Exchange Commission on March 30, 2017. The financial information as of March 31, 2017, the three months ended March 31, 2017 and 2016 is unaudited, but in the opinion of management, all adjustments, consisting only of normal recurring adjustments, considered necessary for a fair presentation of the financial position, results of operations and cash flows at the dates and for the periods presented of the results of these interim periods have been included. The balance sheet data as of December 31, 2016 was derived from audited financial statements. The results of the Company’s operations for any interim period are not necessarily indicative of the results that may be expected for any other interim period or for a full fiscal year. On February 17, 2017, the Company closed an underwritten public offering in which it sold, an aggregate of approximately 2,555,555 shares of common stock, including 333,333 shares sold in connection with the exercise in full by the underwriters of their option to purchase additional shares. The net proceeds of the offering, including the full exercise of the option, were approximately $10.6 million, after deducting the underwriting discounts and commissions and the other offering expenses payable by Aldeyra. The Company’s management believes that its currently available resources, including amounts potentially available under its credit facility (Note 7), will provide sufficient funds to enable the Company to meet its expected obligations into approximately the third quarter of 2018 based on the Company’s current business plan. However, these amounts will not be sufficient for the Company to commercialize its product candidates or conduct any substantial, additional development requirements requested by the U.S. Food and Drug Administration (FDA). Additional funding may not be available to the Company on acceptable terms, or at all. If the Company is unable to secure additional capital, or meet financial covenants that could be implemented under the Company’s term loans in certain circumstances, it will be required to significantly decrease the amount of planned expenditures, and may be required to cease operations. Curtailment of operations would cause significant delays in the Company’s efforts to introduce its products to market, which is critical to the realization of its business plan and the future operations of the Company. Use of estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements, disclosure of contingent assets and liabilities, and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates and assumptions. Recent Accounting Pronouncements In March 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2016-09 Improvements to Employee Share-Based Payment Accounting (ASU 2016-09), to simplify the accounting for stock compensation. This update focuses on income tax accounting, award classification, estimating forfeitures, and cash flow presentation. The Company adopted ASU 2016-09 in the quarter ended March 31, 2017, and it did not have a material impact on the Company’s financial statements.
In February 2016, the FASB issued ASU No. 2016-02 (ASU 2016-02), Leases. ASU 2016-02 requires lessees to recognize on the balance sheet a right-of-use asset, representing its right to use the underlying asset for the lease term, and a lease liability for all leases with terms greater than 12 months. The guidance also requires qualitative and quantitative disclosures designed to assess the amount, timing, and uncertainty of cash flows arising from leases. The standard requires the use of a modified retrospective transition approach, which includes a number of optional practical expedients that entities may elect to apply. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018. The Company does not expect this standard to have a material impact on its financial statements. In November 2015, the FASB issued ASU No. 2015-17, Income Taxes (ASU 2015-17). ASU 2015-17 simplifies the presentation of deferred income taxes by requiring that deferred tax liabilities and assets be classified as noncurrent in a classified statement of financial position. The requirement that deferred tax liabilities and assets of a tax-paying component of an entity be offset and presented as a single amount is not affected by the amendments in ASU 2015-17. The Company adopted ASU 2015-17 in the quarter ended March 31, 2017, and it did not have a material impact on the Company’s financial statements. In April 2015, the FASB issued ASU No. 2015-03, Simplifying the Presentation of Debt Issuance Costs (ASU 2015-03). The amendments in ASU 2015-03 require that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The Company adopted ASU 2015-03 in the quarter ended March 31, 2017, and it did not have a material impact on the Company’s financial statements. In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606), which supersedes the revenue recognition requirements in ASC 605, Revenue Recognition. This ASU is based on the principle that revenue is recognized to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The ASU also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. ASU 2014-09 is effective for fiscal years beginning after December 15, 2017. The Company does not expect this standard to have a material impact on its financial statements. |

| Fair Value Measurements |
Financial instruments, including cash and accounts payable, are carried in the financial statements at amounts that approximate their fair value based on the short maturities of those instruments. The carrying amount of the Company’s term loans under its credit facility approximates market rates currently available to the Company. Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value are performed in a manner to maximize the use of observable inputs and minimize the use of unobservable inputs. ASC 820, Fair Value Measurements, establishes a fair value hierarchy based on three levels of inputs, of which the first two are considered observable and the last unobservable, that may be used to measure fair value, which are the following: Level 1 – Quoted prices in active markets that are accessible at the market date for identical unrestricted assets or liabilities. Level 2 – Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs for which all significant inputs are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 3 – Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. There were no liabilities measured at fair value at March 31, 2017 or December 31, 2016. The following table presents information about the Company’s assets measured at fair value at March 31, 2017 and December 31, 2016:

| Debt Disclosure [Abstract] | |||
| Credit Facility |
The Company’s long-term debt obligation consists of amounts the Company is obligated to repay under its credit facility with Pacific Western (Credit Facility), of which $1.4 million was outstanding as of March 31, 2017. The Company entered into the Credit Facility in April 2012 and it has been subsequently amended to make term loans in a principal amount of up to $5.0 million available to the Company with proceeds to be used first to refinance outstanding loans from Pacific Western, second to fund expenses related to its clinical trials, and the remainder for general working capital purposes. The term loans are to be made available upon the following terms: (i) $2.0 million was made available on November 10, 2014; and (ii) $3.0 million (the Tranche B Loan) which was made available to the Company in May 2016 following the satisfaction of certain conditions, including receipt of positive phase 2 data in noninfectious anterior uveitis. Each term loan accrues interest from its date of issue at a variable annual interest rate equal to the greater of 2.0% plus prime or 5.25% per annum. In November 2016, we amended our Credit Facility such that any term loan the Company draws is payable as interest-only prior to November 2017 and thereafter is payable in monthly installments of principal plus accrued interest over 36 months. The Credit Facility is collateralized by substantially all of the Company’s assets, including its intellectual property. In conjunction with obtaining and amending the Credit Facility, the Company issued warrants to the bank with an aggregate fair value of $266,000, which were recorded as a debt discount. These discounts are being amortized using the effective interest method through the current maturity date of the Credit Facility in November 2018. All amendments to the credit facility were determined to be modifications in accordance with ASC 470, Debt and did not result in extinguishment. At March 31, 2017 and December 31, 2016, the Credit Facility is shown net of a remaining debt discount of $74,500 and $80,000, respectively. |

| Income Tax Disclosure [Abstract] | |||
| Income Taxes |
No provision for federal and state taxes has been recorded as the Company has incurred losses since inception for tax purposes. Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. In assessing the realizability of net deferred taxes in accordance with ASC 740, Income Taxes, the Company considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. Based on the weight of available evidence, primarily the incurrence of net losses since inception, anticipated net losses in the near future, reversals of existing temporary differences and expiration of various federal and state attributes, the Company does not consider it more likely than not that some or all of the net deferred taxes will be realized. Accordingly, a 100% valuation allowance has been applied against net deferred taxes. Under Section 382 of the Internal Revenue Code of 1986, as amended (Code), a corporation that undergoes an “ownership change” is subject to limitations on its ability to utilize its pre-change net operating losses (NOLs) and certain other tax assets (tax attributes) to offset future taxable income. In general, an ownership change occurs if the aggregate stock ownership of certain stockholders increases by more than 50 percentage points over such stockholders’ lowest percentage ownership during the testing period (generally three years). Transactions involving the Company’s common stock, even those outside the Company’s control, such as purchases or sales by investors, within the testing period could result in an ownership change. A limitation on the Company’s ability to utilize some or all of its NOLs or credits could have a material adverse effect on the Company’s results of operations and cash flows. Prior to 2016, Aldeyra has undergone two ownership changes and it is possible that additional ownership changes have occurred since. However, the Company’s management believes that it had sufficient “Built-In-Gain” to offset the Section 382 of the Code limitation generated by such ownership changes. Any future ownership changes, including those resulting from Aldeyra’s recent or future financing activities, may cause the Company’s existing tax attributes to have additional limitations. All tax years are open for examination by the taxing authorities for both federal and state purposes.
The Company accounts for uncertain tax positions pursuant to ASC 740 which prescribes a recognition threshold and measurement process for financial statement recognition of uncertain tax positions taken or expected to be taken in a tax return. If the tax position meets this threshold, the benefit to be recognized is measured as the tax benefit having the highest likelihood of being realized upon ultimate settlement with the taxing authority. The Company recognizes interest accrued related to unrecognized tax benefits and penalties in the provision for income taxes. Management is not aware of any uncertain tax positions. |

| Stock Incentive Plan |
The Company has three incentive plans. One was adopted in 2004 (2004 Plan) and provided for the granting of stock options and restricted stock awards and generally prescribed a contractual term of seven years. The 2004 Plan terminated in August 2010. However, grants made under the 2004 Plan are still governed by that plan. As of March 31, 2017, options to purchase 23,954 shares of common stock at a weighted average exercise price of $3.24 per share remained outstanding under the 2004 Plan. The Company approved the 2010 Employee, Director and Consultant Equity Incentive Plan (2010 Plan) in September 2010 to replace the 2004 Plan. The 2010 Plan provided for the granting of stock options and restricted stock awards. The 2010 Plan terminated in May 2014 upon the initial public offering (Initial Public Offering). However, grants made under the 2010 Plan are still governed by that plan. As of March 31, 2017, options to purchase 489,846 shares of common stock at a weighted average exercise price of $1.58 per share remained outstanding under the 2010 Plan. The Company approved the 2013 Equity Incentive Plan (2013 Plan) in October 2013. The 2013 Plan became effective immediately on adoption although no awards were to be made under it until the effective date of the Registration Statement for the Initial Public Offering. The 2013 Plan provides for the granting of stock options, restricted stock, stock appreciation rights, stock units, and performance cash awards to certain employees, members of the board of directors and consultants of the Company. As of March 31, 2017, the number of shares of common stock authorized for issuance in connection with the 2013 Plan was 2,761,293. On January 1 of each year the aggregate number of common shares that may be issued under the 2013 Plan shall automatically increase by such a number of shares equal to the least of (a) 7% of the total number of common shares outstanding on the last calendar day of the prior fiscal year, (b) subject to adjustment for certain corporate transactions, 1,000,000 common shares, or (c) a number of common shares determined by the Company’s board of directors. As of March 31, 2017, options to purchase 1,724,321 shares of common stock at a weighted average exercise price of $5.73 per share and restricted stock units of 163,902 remained outstanding under the 2013 Plan. As of March 31, 2017, there were 873,069 shares of common stock available for grant under the 2013 Plan. Terms of stock award agreements, including vesting requirements, are determined by the Company’s board of directors or its compensation committee, subject to the provisions of the respective plan they were granted. Awards granted by the Company typically vest over a four year period. Certain of the awards are subject to acceleration of vesting in the event of certain change of control transactions. The awards may be granted for a term of up to ten years from the date of grant. The exercise price for options granted under the 2013 Plan must be at a price no less than 100% of the fair market value of a common share on the date of grant. The Company recognizes stock-based compensation expense over the requisite service period. The Company’s share-based awards are accounted for as equity instruments. The amounts included in the consolidated statements of operations relating to stock-based compensation are as follows:
Stock Options The table below summarizes activity relating to stock options for the three months ended March 31, 2017:
As of March 31, 2017, unamortized stock-based compensation for all awards was $4,933,455 and will be recognized over a weighted average period of 3.09 years. Restricted Stock Units Restricted stock units are not included in issued and outstanding common stock until the shares are vested and released. During the three months ended March 31, 2017, the Company granted a restricted stock unit award for 136,806 underlying shares of common stock with a weighted-average grant date fair value of $5.10 per share. As of March 31, 2017, there were 163,902 outstanding and unvested shares of restricted stock units which had had unamortized stock-based compensation of $808,237 with a weighted-average remaining recognition period of 3.79 years and no aggregate intrinsic value. Employee Stock Purchase Plan In March 2016, the Company’s Board of Directors approved the 2016 Employee Stock Purchase Plan (2016 ESPP), which became effective in June 2016 following the approval of the Company’s stockholders. As of March 31, 2017, the 2016 ESPP authorized issuance of up to a total of 223,263 shares of the Company’s common stock to participating employees. The number of shares reserved for issuance under the 2016 ESPP automatically increases on the first business day of each fiscal year by a number equal to the lesser of (i) 1% of the shares of common stock outstanding on the last business day of the prior fiscal year; or (ii) the number of shares determined by the Company’s Board of Directors. Unless otherwise determined by the administrator of the 2016 ESPP, two offering periods of six months’ duration will begin each year on January 1 and July 1. As of March 31, 2017, there was no activity under the 2016 ESPP. |

| Stock Purchase Warrants |
On January 14, 2015, the Company sold, in a private placement, an aggregate of approximately 1.1 million shares of common stock at a price of $7.00 per share. Investors received warrants to purchase up to approximately 1.1 million shares of common stock at an exercise price of $9.50. The Company raised approximately $7.1 million in net proceeds in the private placement of common stock and warrants. Additionally, on January 21, 2015, in a subsequent private placement, the Company sold an aggregate of 211,528 shares of common stock at a price of $9.33 per share and a warrant to purchase up to 211,528 shares of common stock at a price of $0.125 per share subject to the warrant. The Company raised approximately $1.9 million in net proceeds in the private placement of common stock and a warrant to purchase common stock. In both transactions, the exercise price of the warrants is $9.50 per share. The warrants will expire 3 years from their respective date of issuance. The warrants do not include a net-exercise feature. The warrants may be redeemed by the Company at a price of $0.001 per share upon notice to the holders thereof in the event that the closing bid for Aldeyra’s common stock for each of the fifteen consecutive trading days prior to such redemption is at least $20.00 per share and the average trading volume of Aldeyra’s common stock during such period is at least 50,000 shares per day. Following Aldeyra’s notification to the warrant holders of its exercise of the redemption right under the warrants, the warrant holders will have the option to exercise the warrants prior to the redemption date rather than having them redeemed.
In connection with the Initial Public Offering, the Company issued the underwriters of the offering warrants to purchase up to 60,000 shares of common stock. The warrants are exercisable beginning on May 1, 2015 for cash or on a cashless basis at a per share price of $10.00. The warrants will expire on May 1, 2019. All of the warrants above were outstanding at March 31, 2017. |

| Accounting Policies [Abstract] | |
| Basis of Presentation | The accompanying interim unaudited condensed financial statements and related disclosures are unaudited and have been prepared in accordance with U.S. generally accepted accounting principles (GAAP) for interim financial information and the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all the information and footnotes required by GAAP for complete financial statements and should be read in conjunction with the Company’s financial statements and related footnotes for the year ended December 31, 2016 included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016, which was filed with the Securities and Exchange Commission on March 30, 2017. The financial information as of March 31, 2017, the three months ended March 31, 2017 and 2016 is unaudited, but in the opinion of management, all adjustments, consisting only of normal recurring adjustments, considered necessary for a fair presentation of the financial position, results of operations and cash flows at the dates and for the periods presented of the results of these interim periods have been included. The balance sheet data as of December 31, 2016 was derived from audited financial statements. The results of the Company’s operations for any interim period are not necessarily indicative of the results that may be expected for any other interim period or for a full fiscal year. On February 17, 2017, the Company closed an underwritten public offering in which it sold, an aggregate of approximately 2,555,555 shares of common stock, including 333,333 shares sold in connection with the exercise in full by the underwriters of their option to purchase additional shares. The net proceeds of the offering, including the full exercise of the option, were approximately $10.6 million, after deducting the underwriting discounts and commissions and the other offering expenses payable by Aldeyra. The Company’s management believes that its currently available resources, including amounts potentially available under its credit facility (Note 7), will provide sufficient funds to enable the Company to meet its expected obligations into approximately the third quarter of 2018 based on the Company’s current business plan. However, these amounts will not be sufficient for the Company to commercialize its product candidates or conduct any substantial, additional development requirements requested by the U.S. Food and Drug Administration (FDA). Additional funding may not be available to the Company on acceptable terms, or at all. If the Company is unable to secure additional capital, or meet financial covenants that could be implemented under the Company’s term loans in certain circumstances, it will be required to significantly decrease the amount of planned expenditures, and may be required to cease operations. Curtailment of operations would cause significant delays in the Company’s efforts to introduce its products to market, which is critical to the realization of its business plan and the future operations of the Company. |
| Use of Estimates | Use of estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements, disclosure of contingent assets and liabilities, and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates and assumptions. |
| Recent Accounting Pronouncements | Recent Accounting Pronouncements In March 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2016-09 Improvements to Employee Share-Based Payment Accounting (ASU 2016-09), to simplify the accounting for stock compensation. This update focuses on income tax accounting, award classification, estimating forfeitures, and cash flow presentation. The Company adopted ASU 2016-09 in the quarter ended March 31, 2017, and it did not have a material impact on the Company’s financial statements.
In February 2016, the FASB issued ASU No. 2016-02 (ASU 2016-02), Leases. ASU 2016-02 requires lessees to recognize on the balance sheet a right-of-use asset, representing its right to use the underlying asset for the lease term, and a lease liability for all leases with terms greater than 12 months. The guidance also requires qualitative and quantitative disclosures designed to assess the amount, timing, and uncertainty of cash flows arising from leases. The standard requires the use of a modified retrospective transition approach, which includes a number of optional practical expedients that entities may elect to apply. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018. The Company does not expect this standard to have a material impact on its financial statements. In November 2015, the FASB issued ASU No. 2015-17, Income Taxes (ASU 2015-17). ASU 2015-17 simplifies the presentation of deferred income taxes by requiring that deferred tax liabilities and assets be classified as noncurrent in a classified statement of financial position. The requirement that deferred tax liabilities and assets of a tax-paying component of an entity be offset and presented as a single amount is not affected by the amendments in ASU 2015-17. The Company adopted ASU 2015-17 in the quarter ended March 31, 2017, and it did not have a material impact on the Company’s financial statements. In April 2015, the FASB issued ASU No. 2015-03, Simplifying the Presentation of Debt Issuance Costs (ASU 2015-03). The amendments in ASU 2015-03 require that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The Company adopted ASU 2015-03 in the quarter ended March 31, 2017, and it did not have a material impact on the Company’s financial statements. In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606), which supersedes the revenue recognition requirements in ASC 605, Revenue Recognition. This ASU is based on the principle that revenue is recognized to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The ASU also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. ASU 2014-09 is effective for fiscal years beginning after December 15, 2017. The Company does not expect this standard to have a material impact on its financial statements. |
