When you save the lens, be careful to fully soak the contact lens in the care solution, and do not let the lens float on the top. Contact lenses have a very high water content, and the lenses will become dry and brittle after losing water. If the contact lens is placed out of the care solution for too long, the water will evaporate, and in order to avoid the lens dry and cracked, we should wear the lens as soon as possible, if the delay is longer, you can first put back in the care solution soak for a while and then remove and wear again.

When the eyes are slightly dry, you can use eye moisturizer or preservative-free artificial tears to relieve it, but you need to be careful not to use it too often. When necessary, you can also stop wearing contact lenses for a few days to allow the cornea to repair itself and relieve discomfort. If the indoor environment is relatively dry, you can also use a humidifier to improve the air humidity.

Because color contact lenses add a dyeing layer on the basis of ordinary contact lenses, which is used to print various patterns, it will affect the oxygen permeability of the lens, and it is more likely to cause the problem of corneal hypoxia. As we all know, the cornea is hypoxic for a long time, and the eyes are prone to ulcers, infections and other diseases, which will also stimulate the eyes to produce more sticky secretions. These substances precipitate on the lens, easy to block the oxygen penetration hole, and difficult to completely remove, so color contact lenses should pay more attention to cleaning care, to ensure that as far as possible to remove the residual protein precipitation of the lens.
