For all black contact lenses including sclera contact lenses, we have ready stock which we can post from Melbourne, Australia. Full eye black contacts which are also known as blackout sclera contacts. They are used in Hollywood and movie production studios and can be seen on characters such as Alexander Lyta in Babylon 5 and Ruby in Supernatural. Compared to natural black contact lenses, sclera lenses should only be worn from 4 to 6 hours and it should only be occasionally used for special events. If you wish to wear often, the normal size type would be best. The normal, standard size black can be worn 10-12 hours per day with proper care.
