New research shows that coloured contact lenses, used in order to change one’s appearance, might be associated with a higher risk of the occurrence of infection-related eye damage than regular contact lenses.
A study report printed in Acta Ophthalmologica, a European scientific journal, contains data regarding eye infections and contact lens use. French researchers conducted a survey among contact lens wearers, which included questions concerning, among other things, the types of contact lenses they used, their vision and ocular problems.
The survey showed that eye infections caused by wearing contact lenses led to a visual acuity below 20/200 in 60 percent of those who used coloured contact lenses. By contrast, such poor visual acuity was found in 12 percent of patients suffering from eye infections because of regular contact lenses.
Another important fact discovered by the study was that coloured contact lenses were more often worn by younger people. Moreover, the research revealed that performers (who constitute a large proportion of those who use coloured contact lenses) had more problems disposing of them correctly, all of which may explain the differences in the data concerning coloured and regular contact lenses.
