Clinical research conducted by global biopharmaceutical corporation Johnson & Johnson has identified some positive characteristics of UV-Blocking contact lenses.
A paper was presented at the 2012 British Contact Lens Association Clinical Conference on May 25th and indicated that blocking the transmission of UV light could help to preserve the eye's macular pigment density.
The Eye journal recently published a study that underlined the fact that macular pigment contributes to the protective functions of carotenoids.
Lead author of the Johnson & Johnson research Professor James Wolffsohn, who is also the deputy executive dean for Life and Health Sciences at Aston University in Birmingham, explained that chronic UV light exposure could be a significant contributor to the eye's ageing process.
"Wearing UV-blocking contact lenses could play a contributory role in maintaining the eye's macular pigment density which, in turn, may play a role in helping to delay the development of macular degeneration," the expert commented.
