PROSPECTUS SUPPLEMENT
(To Prospectus dated October 8, 2024)

Up to 15,769,445 Shares of Common Stock Underlying Warrants to Purchase
Shares of Common Stock

This prospectus supplement, dated January 16, 2025 (the "Supplement"), filed by Eyenovia, Inc. (the "Company"), modifies and supplements certain information contained in the prospectus (the "Prospectus") included in the Company's Form S-3 Registration Statement declared effective by the Securities and Exchange Commission on October 8, 2024. This Supplement is not complete without, and may not be delivered or used except in connection with, the Prospectus.

On January 16, 2025, the Company reduced the exercise price for certain of the Company's outstanding warrants issued on March 7, 2022, August 29, 2023 and July 1, 2024 (together, the "Warrants"), exercisable for an aggregate of 15,769,445 shares of the Company's common stock, par value $0.0001 per share (the "Common Stock"). The exercise price of the Warrants was reduced from $0.69 per share of Common Stock to $0.0659 per share (the "Reduced Exercise Price"). As a result of the Reduced Exercise Price, if all of the Warrants are exercised for cash, we would receive gross proceeds of approximately $1.04 million.

Other than the reduction in the per share exercise price for the Warrants, all other terms and provisions of the Warrants remain unchanged.

This prospectus relates to the Common Stock issuable upon exercise of the Warrants.

The information in this Supplement modifies and supersedes, in part, the information contained in the Prospectus. Any information that is modified or superseded in the Prospectus shall not be deemed to constitute a part of such Prospectus, except as so modified or superseded by this Supplement. We may further amend or supplement the Prospectus from time to time by filing additional amendments or supplements. You should read the entire Prospectus and any amendments or supplements carefully before you make an investment decision.

Our Common Stock is listed on The Nasdaq Capital Market under the symbol "EYEN." On January 15, 2025, the last reported sale of our Common Stock on the Nasdaq Capital Market was $0.0659 per share.

Investing in our securities involves a high degree of risk. Please read the information under the heading "Risk Factors" contained in the Prospectus and in the documents incorporated by reference into the Prospectus and this Supplement.

Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities or determined if this Supplement or the accompanying Prospectus is truthful or complete. Any representation to the contrary is a criminal offense.
