Why Must I Remove Contacts Before Latisse?

i am unde the impression that applying latisse with contacts still on actually buffers the iris against latisse, thereby preventing unwanted changes in color.

Always remove your contact lenses before using Latisse

When Latisse is applied to the edge of the eyelid, a very small amount gets into the tears that moisturize your eyes.  The Latisse that is in your tears travels around your contact lens.  If you wear soft lenses it is also absorbed by the lens. In addition Latisse contains a preservative called benzylkonium chloride that is not good for your lenses.

It is also important to remember that properly applied Latisse is very unlikely to cause a change in your iris color.

Thank you for your question. It is recommended that you remove your contact lenses before appling Latisse because the drops may get into your eye and then affect the contact lens itself.  Yes, it is stated that there is a possibility of changing the iris color but there has been no evidence of this reported.  The more common side effects of Latisse is the redness / itching around the eyelid area.

When properly applied, Latisse will not change the color of your irises. Additionally, the ONLY way to affect the iris color is if you already have a bit of brown specks in your eyes, i.e. you have green or hazel eyes. Latisse does not have the ability to make blue eyes turn brown, or anything like that. And really, this iris changing affect was only reported when it was used to treat glaucoma and thereby put directly in the eye - not around it like you do for Latisse and eyelashes. Thus, there is no need to protect your irises with contacts; in fact, if anything did get in your eye, having a contact lense in might trap the liquid more!

It is not necessary to worry about prevention eye color changes from using Latisse.There is no evidence to suggest that Latisse will change your eye color. The eye is exposed to a very small amount of Latisse even when it is properly applied as directed to the upper eyelid margin using the supplied applicator. This has been demonstrated by applying a colored dye to the eyelid margin and watching its migration. Over two and a half million prescriptions for Latisse have been filled with no confirmed reports of iris pigmentation changes.

It is true that one very rare risk is an increase in brown pigmentation in the irises in green or hazel eyes. However, I haven't seen this occur with any of my patients to date.
