2. Is the higher the water content of the lens, the better?
When wearing contact lenses for a long time, the moisture of the lens itself will be lost due to evaporation, but the contact lens itself does not produce water. At this time, the lens will absorb tears to maintain the original moisture content. Therefore, the lower the water content, the less chance of dry eyes.
The water content of Coleyes lenses is 40%, which is considered as low water content lenses.
Remind: If your eyes are dry, or you live in a dry environment or area, it is not recommended to wear high water content contact lenses.
3. What's the material of Coleyes's lenses?
