Not recommended for long wear Wearing contact lenses is equivalent to wearing a "mask" that is not breathable to the cornea. Doctors suggest that ordinary contact lenses are best worn within 6 to 8 hours, and cosmetic contacts are best worn for about 2 hours. If worn for a long time, it may cause eye complications. |
