1, eyes were damaged by pigment layer.
Cosmetic contact lenses contain pigments, and most small brands of cosmetic contact lenses are directly printed on the lens surface. If the production technology does not pass, the pigment may fall off in the future, damaging the eyes, causing allergies, irritation and inflammation to the cornea and conjunctiva.
2. The field of vision narrows when the eyes see things.
In order to pursue color exaggeration, some cosmetic contact lenses use smaller optical areas, which will reduce the vision of the eyes. Generally, the dyed part has poor light transmission, so after wearing it, the visual field will be reduced, and there is a feeling of "seeing a leopard in a tube", which is very unfavorable to drivers and athletes. It is suggested to consider the lens with large optical area when choosing.
3. Corneal hypoxia
Some cosmetic contact lenses have low water content and poor oxygen permeability, and some lens pigments are printed on the surface of the lenses, which reduces the oxygen permeability of the lenses. Long-term corneal hypoxia will lead to complications such as envy, discomfort and corneal neovascularization, which will affect corneal health.
4. Eye discomfort
Traditional cosmetic contact lenses, due to more deposits and pigments on the lens surface, will cause poor wettability of the lens and easily lead to dry eye, mainly manifested as fatigue, sore eyes, tears, dryness, burning eyes and even blurred vision.
