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

After wearing colored contact lenses, they will make the eyes look more lively and have a certain magnifying effect, so many people like to wear colored contact lenses. Colored contact lenses have an expiration date. Can you continue to wear them once they are expired?

If your contact lenses are expired, it is recommended that you do not continue to wear 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. Therefore, try not to wear expired contact lenses. You can replace them with new ones or a pair of frame glasses. If you insist on wearing expired contact lenses, it may cause additional side effects or complications.

If you continue to wear expired contact lenses, it will cause discomfort to your eyes, and in severe cases, it may cause eye infection. Since expired contact lenses will become deformed due to dehydration, continuing to wear them will increase the foreign body sensation in the eyes and make it impossible to continue wearing them. In daily life, you need to regularly care for and maintain your contact lenses. When caring for your contact lenses, you need to pour the care solution into the contact lens box. Do not rinse the contact lenses directly with tap water, as this may cause certain damage and contamination to the lenses.

1. Look at the color depth: Colored contact lenses usually have color patterns on one side and no color patterns on the other side. Put the colored contact lenses in the palm of your hand and observe them carefully. Usually, the side with deep and clear color patterns is the front side, while the side with relatively unclear color patterns is the back side.

2. Look at the shape of the contact lenses: Keep your fingers dry, place the contact lenses on any finger and observe their shape. If they are shaped like a round bowl, a standard semicircular shape, then it is the front side. If they are shaped like a small dish with the opening opening to all sides, then it is the back side.

3. Squeeze the contact lenses to distinguish: After cleaning your hands, take the contact lenses between your thumb and index finger, and squeeze them gently. Be careful to be gentle. After squeezing, the front contact lenses will close inwards, while the back contact lenses will collapse outwards.

Brown and black contact lens colors are the most natural colors, because everyone's eyes are basically brown or black, so sisters who want a natural magnification effect should choose contact lens colors that match their eye color.
