The good news is that six months after Laser Eye Surgery, you can, in most cases, wear coloured or cosmetic contact lenses. You will, however, need to see your optometrist before purchasing any coloured lenses as the shape of your eyes will have changed due to the surgery.
In the fifth day, you can wear it within 12 hours, but the regular wearing time for the ordinary contact lenses is 8 hours. For the rigid gas permeable contact lens, the wearing time is between 10 and 12 hours, so it all depends on the oxygen permeability of the contact lens. 09/10/2012. good (0) Report Abuse.
