Ask the experts - Sunglasses, always a good idea?
We asked the experts at Davis Optometrists to shed some light on the myths about sunglasses, and the importance of good quality lenses to prevent long term damage to your eyes.
How should we protect our eyes from damage from UVA and UVB rays?
Good quality sunglasses! In the same way that covering up and wearing sun screen is the only way to protect your skin, the only way to really protect your eyes from the damaging effects of UVA and UVB rays is to wear good quality sunglasses. And maybe invest in a wide brimmed hat or cap!
How do I know if my sunglasses are good quality and will protect my eyes efficiently from damage?
By buying from a reputable retailer and checking the labelling - ALL good quality sunglasses lenses will be labelled if they protect your eyes from 99-100% of UVA and UVB rays. Those labelled with “UV400” will block all light rays with wavelengths up to 400 nanometers (this covers 100% of UVA and UVB rays).
Sunglasses that don’t block all UVA and UVB rays will only filter out the glare and ambient light and not offer any protection, or prevent the long term damage to your eyes.
What’s the difference between UVA and UVB rays?
UVA rays can damage your eyes over a long period of time, or with excessive exposure, where UVB rays can very rapidly damage the eye tissue if your eyes aren’t appropriately protected.
All the sunglasses we offer at our branches across Leics, Northants and Bucks block 100% of UVA and UVB rays, and will be fitted by one of experienced team to ensure maximum levels of protection. We also offer prescription sunglasses and specialist polarized lenses to reduce glare further during sports or when driving.
