You can make any eyeglasses or sunglasses into bifocals with Optx20/20 reading lenses. Each pair of lenses comes with two plastic reading lenses that can be applied easily with water to your eyeglasses or sunglasses. You can trim the lenses with scissors to fit your own eyeglasses or sunglasses, and the lenses are removable and reusable.
Optx20/20 lenses are non-prescription lenses and are not intended to replace any prescribed corrective lenses or examinations by an eye care professional. We recommend regularly scheduled eye examinations to help you maintain healthy eyes.
Optx20/20 reading lenses use HydroTacTM technology to hold the lens in place. There are three simple steps to applying Optx20/20 reading lenses to your eyeglasses or sunglasses:

• For best results, do the installation at a sink with running water.
• Clean your eyeglasses or sunglasses with warm water and add a few drops of water to the inside sides your eyewear lenses.
• Place each reading lens curved side down on the drops of water and position each reading lens in the lower inside portion of your eyewear lenses, approximately 2.5 apart.
• Pat dry with a lint-free towel and set your eyewear aside to dry completely.
