"My eyes burn when I put in my lenses."
This shouldn't happen, and often when it does, it's because you are unintentionally contaminating your lenses.
Contact lenses retain substances they come into contact with, such as skin lotions, soaps with moisturizers and perfumes, food oils and cosmetics.
These substances can create a burning sensation if they contact your eyes. Therefore, it's important to thoroughly clean your hands before touching your contact lenses or your eyes.
Use soaps that are free of moisturizers and perfumes. Ivory, Dial Basic and Dial Pure & Natural are brands that are sometimes recommended by eye care professionals. Wash your hands thoroughly and dry them with a lint-free cloth before handling your contacts.
Also, consider trying daily disposable contacts. Because you discard these lenses after a single use, there is less risk of them becoming contaminated.
