The main enemy we are fighting with our sunglasses is UV- so what are the harmful effects of UV?
- Cataracts (most common)
- Macular degeneration
- “Sunburnt” of the eye, known as photokeratitis
- Growths on the eye (pterygium)
What constitute a good pair of sunglasses?
- Blocks out 99 to 100% of UVA and UVB radiation, as UVC is absorbed by the ozone layer
- Reducing the amount of direct and reflected light (also known as glare) that enter the eyes, while keeping your vision clear
- Does not affect colour recognition or colour perception
- If you are involved in sports or activities that may be potentially hazardous to your eyes, the lenses should be impact-resistant (also known as polycarbonate) to give you the maximum eye protection
- The colour of the sunglass lenses does not affect the UV protection!
- Wide brimmed hat
- Transitions contact lenses
How to choose a pair suitable for me?
- If you are under the sun for prolonged periods, consider wraparound frames for all-round protection from the sun’s ray
- If sunglasses are done with prescription, ensure that the lenses are free from peripheral distortions
- Consider polarised lenses if you are affected by glare reflected from water or glass surfaces, or require greater visibility during fishing or other water sports
- Lastly, not to forget our younger ones, that is the kids and teenagers, who may be more active and spend more time under the sun
