Contact Lens Guide

 

For your eye health, please ensure that your contact lenses are prescribed by registered optometrist. Optometrist should give instructions in proper handling and care of contact lens, which includes contact lens insertion and removal, lens cleaning, disinfection and storage procedures (applicable to non-daily disposable contact lenses).

 

1. Contact Lens insertion:

Step 1: Peel back the foil closure to reveal the lens before washing your hands. It would be easier to wear the lens with dry hands.

Step 2: Remove the lens from its storage case and examine to be sure that it is moist, clean and free of any nicks or tears. If the lens is damaged, please use a new lens instead. Take out the lens by your forefinger and place the lens on your forefinger (Remark: always wear the lens before applying makeup)

Step 3: Verify that the lens is not turned inside out by checking its profile before you wear the lens. The lens should assume a natural, curved, bowl-like shape. If the lens edges tend to point outward, means the lens is inside out.

Step 4: Lift the upper and pull down lower lid so that you can see the cornea completely, make sure your eyelashes do not obstruct the lens insertion.

Step 5: Keep your both eyes open and hold your eyelids, use the forefinger to place the lens on the eye. When the lens placed on the eye, look down and gently release the fingers. Blink gently to avoid the lens drop out.
