Absolutely safe. Coleyes contacts have been certified by the FDA, CE, and international ISO 13485 certification. Product quality has always been our top priority, so you can wear Coleyes's contact lenses with complete confidence.
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?
The main material of Coleyes lenses is Hema + NVP, which belong to non-ionic material.
The non-ionic material is the addition of NVP ingredients, so that the lens becomes very light, thin and soft, and is not easy to produce protein precipitation. This is a non-ionic material.
Non-ionic material lenses are suitable for people with sensitive eyes and strong foreign body sensation.
