Sunglasses and prescription sunglasses


Here comes the sun


It is important to protect your eyes from the sun’s harmful rays by wearing sunglasses. The risk of UV damage can occur not only as a result of direct sunshine, but also from light being reflected from surfaces such as sand, snow, water and concrete. Sunglasses give comfort in very bright conditions by reducing the amount of light reaching the eye and protect the eye from damaging UVA and UVB light.

  • UVA radiation penetrates deeply in the eye causing damage to the crystalline lens and retina. This can accelerate the ageing process and increase the risk of developing cataracts and age-related macular degeneration, which can seriously impair vision.
  • UVB radiation is normally absorbed at the surface of the cornea but can also reach the retina. Excessive exposure can cause permanent damage to both the cornea and conjunctiva. However, UVB damage can be halted if further exposure is avoided.

Children are thought to be at a greater risk from UV damage because the cornea and lenses in their eyes are much clearer allowing more light to reach the retina.

Most of the sunglasses at SightDirect are glazable with prescription lenses, including single vision, bifocal and varifocal.

Eyeglasses and sunglass will normally be different sizes. Sunglass sizes are normally much larger than eyeglasses in order to give you more coverage from the sun and more protection.
