Protect your eyes
Fashion aside, sunglasses serve an important purpose: protecting eyes from the harmful rays produced by the sun. You’re probably aware of the need to protect your skin from the sun, but it’s equally important to protect your eyes.
Here at Viewpoint Vision Services Ltd in St Helens, we can provide you with UV sunglasses which will help to protect your eyes in addition to giving you clear vision. Get in touch with our team today.
Quality protection
Ultraviolet (UV) radiation consists of invisible rays from the sun. The three bands of UV light are: UVA, UVB and UVC. UVC rays are of little concern as they are absorbed by the upper atmosphere and do not reach the earth’s surface.
UVB rays are the ones that burn the skin and can damage the eyes. Combined with cold wind and snow, UVB has the potential to cause snow blindness (photokeratitis), a temporary but painful problem in the cornea of the eye.
Keeping eyes healthy
Although not all scientists agree, there is some research that suggests that daily exposure to UVB in very bright sunlight over a period of many years may cause cataracts. Experts also suspect that the primary cause of eye growths such as pinguecula or pterygia is exposure to UVB rays.
People with cataracts (or who’ve had cataract or lens replacement surgery), macular degeneration, and retinal dystrophies should be extra careful.
Excellent features
The most important feature to look for in a sunglasses lens is how much UV radiation it absorbs — you want 100% for maximum protection. Look for sunglasses that protect you from 99% to 100% of both UVA and UVB light. This includes those labelled as “UV 400,” which blocks all light rays with wavelengths up to 400 nanometres.
Quality lenses
It is also important to get lenses that are ground rather than punched, to minimise distortion. You may want to consider wraparound sunglasses to prevent harmful UV rays from entering around the frame. Polarised lenses are great for those who spend time on water or drive regularly. The polarisation cuts out the light coming from the horizontal meridian while allowing in the light coming in from the vertical meridian. In other words, it blocks the light that reflects in from water or the highway, reducing glare.
We also offer eye treatments
Laser eye surgery
Laser eye surgery may help with conditions including short-sightedness, far-sightedness, astigmatism, and presbyopia.
Keratoconus
Keratoconus is a degenerative disorder of the eye in which structural changes within the cornea cause it to thin and change to a more conical shape than its normal gradual curve.
MIGS
A vitrectomy is a type of eye surgery to treat various problems with the retina and vitreous. Your surgeon will remove your vitreous and replace it with another solution.
