Can I still wear expired contact lenses? What will happen if I wear expired contact lenses?

Once opened, the beauty contact lenses have an expiration date. What will happen if you accidentally wear expired beauty contact lenses? Can you still wear them two days after the expiration date?

If your contact lenses are expired, it is recommended not to continue wearing them. You can replace them with new ones. Because contact lenses are worn for too long, protein deposits from the eyes will form on the inner surface of the lenses. Excessive deposits will affect the water content and oxygen permeability of the contact lenses. If you continue to wear them, the oxygen permeability of the cornea will decrease, and the cornea will swell due to lack of oxygen or water, which will cause additional complications.

1. Expired cosmetic contact lenses may become dehydrated and deformed, and the foreign body sensation will intensify. When the contact lenses reach the discarding period, the water loss will be very serious, and the lenses may even be deformed. The foreign body sensation will be very strong and can no longer meet the wearing needs.

2. The lenses of contact lenses will begin to break, and wearing them will be harmful to the health of your eyes.

3. The oxygen permeability of expired cosmetic contact lenses will deteriorate, affecting the normal metabolism of the cornea.

4. The anti-virus and antibacterial drugs and functions of expired cosmetic contact lenses may have disappeared or weakened. If you continue to wear them, it will only cause eye infections and various complications of eye diseases, and in severe cases, even blindness.

5. Wearing expired contact lenses will cause your eyesight to deteriorate because their transparency and refractive effects are very poor, which will increase the burden on your eyes and make your eyesight worse and worse.

Some people who wear contact lenses find that their eyes turn red, itch and tear during use, which may indicate an allergy to the contact lenses. The most common cause of this problem is common irritants, including pollen and white flakes, which can form on the lens, which means that the allergy continues to rub the eyes. Others are allergic to the lens of the contact lens solution or the material itself. In addition, the occurrence of protein contact can cause giant papillary conjunctivitis (GPC), where conjunctivitis occurs on the bumps because the surface is very tight, causing an allergy-like condition.

Generally speaking, cosmetic contact lenses will not fall into the eyes, but it is possible that some special reasons may cause cosmetic contact lenses to fall into the eye sockets, such as rubbing the eyes and rubbing the cosmetic contact lenses into the eyes.

Cosmetic contact lenses are decorative colored flat contact lenses, which are developed on the basis of contact lenses and are used to decorate and change the color of the cornea. They contain more chemical ingredients, so it is not recommended to wear them for a long time. Long-term wearing of inferior contact lenses can cause blindness.
