Can I squint for a while when wearing colored contact lenses? How long can I wear colored contact lenses?

Colored contact lenses are a very popular type of colored contact lenses that can change the color of the pupils and enlarge the eyes. Many young men and women like to wear them. However, wearing colored contact lenses to sleep is very harmful, so everyone should be careful.

You can close your eyes for a while when wearing them, but don't sleep on your stomach. Blink vigorously after waking up. It is generally not recommended to wear cosmetic contact lenses while resting, as this can easily damage the cornea. When wearing cosmetic contact lenses, you must pay attention to eye hygiene, don't wear them for a long time, and be sure to take them off before going to bed. If your eyes are uncomfortable, you must take them off in time.

First of all, let's talk about contact lenses. In theory, contact lenses can be worn for up to 14 hours a day. It is generally recommended not to wear them for more than 8 hours, because contact lenses are in direct contact with our cornea. Long-term wearing may cause our eyes to be deprived of oxygen, which is very harmful to eye health. However, cosmetic contact lenses are colored contact lenses with pigment layers, which have worse oxygen permeability to the eyes, so the wearing time of cosmetic contact lenses cannot be longer than that of contact lenses, and it cannot exceed eight hours at most. Therefore, we recommend that the daily wearing time of cosmetic contact lenses and contact lenses should not be too long, and generally about 8 hours is the best. If it is the first time to wear, slowly adapt to wearing them according to 2 hours on the first day and 4 hours on the second day. In addition, the use time of cosmetic contact lenses should not be too long. The period of wearing cosmetic contact lenses depends on the daily wearing time to prevent deposits from causing problems with the lenses. The longer the contact lenses are worn, the higher the chance of problems with the glasses. Generally speaking, if they are worn according to the care standards, protein deposits cannot be completely removed, and they will accumulate more and more, making the lens oxygen permeability worse and the corneal hypoxia worse. Therefore, it is best to discard annual disposable contact lenses after 8 to 10 months, and semi-annual disposable contact lenses after 4 to 5 months.

1. New contact lenses need to be soaked before wearing (except daily disposable lenses, but daily disposable lenses are not recommended for the first time). Soak the removed lenses in the lens box with fresh care solution for about 4 to 8 hours. The longer the contact lens cycle, the longer the soaking time. In short, if you choose annual disposable lenses, you must soak them for more than 8 hours.

2. Before wearing cosmetic contact lenses, you need to clean your hands and dry them with a lint-free towel. No moisture should be left on your hands.

3. In a clean and tidy environment, place the necessary lenses, tweezers and other tools.

4. Place the lens on the tip of your right index finger, hold it in front of your eyes and observe the front and back sides. The edge that is bowl-shaped is the front side, and the edge that is disc-shaped is the back side.

5. Facing the mirror, use your left index finger to gently pull the upper eyelid, and use your right middle finger to gently pull the lower eyelid (remember to pull from the root of the eyelashes), then gently move the lens on your right index finger towards your eyes, and you can look slightly upwards.

6. When the lens is close enough to the eyeball, it will automatically adhere to the eyeball. At this time, do not blink quickly. Instead, turn your eyeballs a few times, then close your eyes and turn them a few more times to make the lens fit better to the eyes.

7. After wearing, let your eye adapt, and then wear the other eye. The operation method is the same as before.

How to distinguish left and right eye with cosmetic contact lenses

If the degree of the newly unpacked contact lenses is the same for both eyes, there is no need to distinguish them and they can be worn directly. If the degree of the two eyes is different, just find the corresponding eye degree and wear it on the corresponding left and right eyes. Wearing the wrong contact lenses can easily cause symptoms such as dizziness, blurred vision, unclear vision, etc. After wearing the contact lenses, whether the degree of the two eyes is different, you need to distinguish the left and right eyes. You can take off one lens first and put it on one side of the companion box. The left and right are usually marked on the contact lens box, L is left, R is right, just pay attention when putting it in, so that you won't get confused next time you wear it.
