Pigment falls off, resulting in damage to the ocular surface tissues and infection;

2. In order to reduce the cost of some inferior colored contact lenses, unqualified pigment materials are selected, which have poor oxygen permeability, which directly affects the oxygen permeability of the lens, thereby affecting the oxygen flow on the surface of the cornea. Hypoxia on the ocular surface will cause conjunctival hyperemia, and corneal epithelial cells will also be affected, and the resistance will become weak. If there is long-term hypoxia, the surrounding tissues will grow into the cornea with new blood vessels. If further development, the visual field may be blocked.

3. Inferior colored contact lenses have different sizes of the central optical zone. When the diameter of the pigment inner ring is smaller than the pupil diameter, the field of view will be blocked, which will affect the clarity and integrity of the imaging of things, and it will also affect the night time because of this. Eyesight, so it is recommended not to wear colored contact lenses when driving.
