How to distinguish the front and back of the cosmetic contact lenses

For those who love beauty, colored contact lenses are an indispensable artifact. But as a novice, sometimes I can’t tell the front and back of the contact lenses apart, and I’m worried about what to do if I wear them upside down? Will it affect my eyesight? Does it look weird from the outside? Will it be uncomfortable to wear them by yourself? With these, the editor will introduce to you how to distinguish the front and back of cosmetic contact lenses. There are generally three methods.

First, the lens curvature observation method.

Place the contact lens flat on your index finger with the opening facing upward, and carefully observe the shape of the lens edge. If you find that the edge is rounded, with a large curvature and a bowl shape, it is the front side; if the edge is slightly turned outward and is disc-shaped, it is the back side. 2

Second, the finger squeeze method.

Place the contact lens between your index finger and thumb and squeeze it. If it is the front side, it will close inward and be more elastic; if it is the back side, it will collapse outward and have no elasticity. (Be careful not to use too much force with your fingers)

Third, the lens pushing method.

Put the contact lens in a double box filled with care solution, and use the lens clip to push the lens. If it is the front side, the lens will be suspended and easy to push; if it is the back side, the lens will sink to the bottom of the box and difficult to push.

If you don’t use and care for your cosmetic contact lenses properly, your eyes will be greatly affected. So what should you pay attention to when wearing colored contact lenses? (Emphasis on nursing)

Things to note when wearing contact lenses:

1. If you wear your colored contact lenses for more than 7 hours a day and do not take them off when sleeping. It is easy to increase eye secretions and put the cornea in danger.

2. If the dual-combination care solution is not changed for a month, then the annual disposable contact lenses can basically be discarded in one month. 3

3. If you change the care solution every day but do not deep clean your contact lenses, then don’t blame your contact lenses for rubbing your eyes, as your eyes will have a serious foreign body sensation. 4

4. If you haven't worn contact lenses for a long time and the edges of your contact lenses are curled due to lack of care solution, don't worry. Soak them in care solution overnight and they will return to their original shape. Cleaning it again should be fine. 5

5. Always use boiling water to scald your joints. 6

6. The new contact lenses you just bought are soaked in saline solution. After opening, you need to soak the contact lenses in care solution for 24 hours before you can start wearing them.

7. Remove makeup first and then take off your contact lenses, then put on your contact lenses and then put on your makeup.
