Step 1 - Wash hands, glasses, and OPTX 20/20 Reading Lenses with Original Dawn Dishwashing Liquid Soap (no lotions-no oils) and warm water to remove any dust, dirt or oils. Rinse thoroughly with clean, warm water. Never use any type of soap containing lotions or oils. This will damage the lenses. 

Step 2 - Using clean warm water apply the lens to the inside lower half of your glasses. Position each lens so the curved side presses down. Apply one lens at a time. Suggestion: 2 1/2" apart although they may be applied to suit your own needs.  

Step 3 - To check for proper placement, put on your glasses and look through your OPTX 20/20 Reading Lenses. Placement adjustments are easily made by sliding your lenses while they are still wet. Note: Your vision through the lenses will be blurry until they have completely dried. This is completely normal and part of the Hydro Tac Bonding Technology process. 

Step 4 - When properly positioned, press the excess water gently to the sides. Pat dry with a lint-free towel or tissue. Allow the OPTX 20/20 lenses to dry completely before using. Set them aside. This usually takes at least 12 hours or even better: Overnight. This process is part of the Hydro Tac Technology that creates the bond. OPTX 20/20 Reading Lenses are removable and can be reinstalled by repeating these same simple easy instructions.
