I've used Latisse for about a week and I suddenly have blurred and double vision! Is this permanent?

Latisse has been FDA approved and specifically desgined for application to the eyelid for eyelash growth. Bimatoprost alone is not indicated for this use.All the Best.  

Latisse can make your lashes grow longer, thicker and darker, but there is no guarantee that they'll curl as well. To give your lashes shape, an eyelash curler can be used.

Diet supplements and nurturing eyelashes and help to strengthen your eyelashes. Latisse helps to gorw lashes better than any other treatment known at this time. Hope this helps.

Yes. You can continue wearing contacts when you're using Latisse. The key is to wait about 15 minutes after applying Latisse before re-inserting as this gives the product enough time to dry.

Your eyelashes will grow back. You will have to wait a full eyelash growth cycle which is different for everyone but somewhere between 3 - 16 weeks. Latisse is not necessary for this to take place.

I can not give any recommendations as I am not well versed with Revitalash. Although, these symptoms are usually treated with flushing the eye with water or normal saline, discontinue use of the product and follow up with the manufacturer of the product. All the best.
