You must wear UV-protective glasses from lens implantation until after the last light treatment is complete. Until the LAL is locked in, exposing the lens to UV light sources (including the sun) could potentially modify the prescription. Total wear is typically 4–6 weeks; however, this can vary depending on the number of light treatments needed. You must wear the UV-protective glasses supplied to you as they have a special protective coating that no other glasses have. If you lose a pair, continue to wear the other pair provided and contact your eye clinic to replace them. Ask your doctor what activities you can participate in while completing light treatments. For example, you MUST NOT go to a tanning studio, get in a tanning bed, or receive facial beauty treatments (such as laser hair removal or permanent makeup).  Please watch the short video below.
