What will happen if I leave contacts in when I put a drop of Pataday allergy in my eye?

Hello,

Do not use olopatadine ophthalmic while you are wearing contact lenses. Olopatadine ophthalmic may contain a preservative that can be absorbed by soft contact lenses. Wait at least 10 minutes after using olopatadine before putting your contact lenses in.
Avoid wearing contact lenses while your eyes are red or irritated.

Take care.-

A couple of things may happen.
Firstly the eye drops may damage the lens .
Secondly, because the eye drops can be absorbed into the lens, and therefore in contact with the eye, there is a greater risk of experiencing a sensitivity reaction.
