Because there are legalities and specific guidelines in selling contact lenses, this is not the place to sell your unused lenses.

Contact lenses are medical devices and sales are strictly regulated by the FDA (Food and Drug Administration) and the FTC (Federal Trade Commission).

The FDA also requires a valid prescription and without FDA approval it’s against the law to sell or distribute contact lenses.

I hope this information is helpful for you.
