More and more sportspeople use coloured contact lenses reducing glare and improving contrast to see better in bright light. In consequence, several researchers, FC Horn, GB Erickson, B. Karben and B. Moore, have recently decided to examine if such lenses are really effective. For that purpose, they compared the performance of Maxsight Amber contact lenses and regular contact lenses with and without Eye Black grease (used by a number of athletes to reduce glare).
The study included seventeen subjects, who were fitted with two types of contact lenses (clear and Maxsight ones) and wore them with or without Eye Black grease. Then the researchers evaluated visual acuity in low contrast conditions, after which the subjects answered questions concerning the performance of each type of contact lenses.
The tests showed that visual acuity was significantly better when Maxsight contact lenses were used; Black Eye grease slightly improved the performance of clear contact lenses, but did not improve the performance of Maxsight lenses. The subjects expressed a clear preference for Maxsight contact lenses, which proves their effectiveness: athletes can benefit from wearing them during various kinds of outdoor competitions.
