Evaluation of Selenium coated lenses

This study is testing whether contact lenses coated with a special mineral called selenium can be worn safely and help prevent bacteria from growing on the lens surface. Bacteria growing on contact lenses is a leading cause of eye infections in lens wearers. Researchers hope that selenium-coated lenses might reduce this risk. Neither the people in the study nor the eye care providers giving the lenses will know which type of lens they are using. You may be eligible if: - You are 18 years of age or older - You are able to understand and sign a consent form - You are willing to follow the lens-wearing schedule set by the study team - Your eyes are healthy enough to wear contact lenses - Your vision can be corrected to at least 20/40 in each eye with contact lenses You may NOT be eligible if: - You have a medical reason that prevents you from safely wearing soft contact lenses - You have an eye condition or take medication that could affect your eyes or be made worse by contact lens wear - You have pre-existing eye irritation - You have had eye surgery in the 12 weeks before joining the study - You have had laser eye surgery (corneal refractive surgery) Talk to your doctor about whether this trial might be right for you.
