Whitby & Co offer a wide range of prescription sunglasses from brands such as Maui Jim, Tom Ford, Faconnable and Spine.
Photochromic lenses are designed to react to different light conditions encountered during the day. They change colour and become darker in response to increased exposure to ultraviolet radiation (usually found in brighter light conditions), thereby protecting your eyes from harmful UV rays and making it easier to see in such conditions. In less bright (low UV) light conditions, photochromic lenses remain lightly tinted, enabling the wearer to see clearly.
- High-quality photochromic lenses adapt quickly to changing light conditions and provide maximum protection against UV radiation.
- Photochromic lenses offer flexibility to a wearer of prescription sunglasses and can be used indoors and outdoors.
- Photochromic lenses are available in glass or plastic, but polycarbonate lenses are best and have the additional advantages of being much lighter as well as being shatter and scratch resistant.
Our opticians would be happy to assist you in assessing whether you would benefit from changing to photochromic lenses.
Polarised lenses are available in grey, brown and sometimes in grey-green (G15, “Ray-Ban” lens colour) and may be used by both prescription and non-prescription wearers. These lenses are designed to eliminate glare, which often arises through the reflection of light on shiny or bright surfaces such as water, snow, glass or metal.
Polarised lenses assist more comfortable vision by eliminating glare and are suitable for many sports, such as fishing, skiing and water sports.
Ultra Violet protection
The skin and eyes are at risk from ultraviolet radiation emitted from the sun. Ultraviolet radiation is below the visible spectrum of radiation emitted by the sun and broadly falls into three categories: UVA, UVB and UVC. UVC rays are usually absorbed by the upper atmosphere. The harmful effects of radiation are usually as a result of UVA and UVB radiation.
Always wear your prescription sunglasses outdoors. Even if it is overcast or raining, UV radiation can still be high and could cause damage to your skin and eyes. Bear in mind that UV radiation levels are higher in the following types of conditions and greater protection may be required:
- During summer
- In the middle of the day
- On the beach or at sea where there is little or no shade provided by trees or buildings
- At high altitude (e.g. when skiing)
- Choose sunglasses that block UV rays, from both UVA and UVB rays
- Don’t forget that babies and small children also need good protection – whether they like it or not!
We also supply prescription and non-prescription eyewear for a wide range of sports including: skiing, diving, swimming, shooting, cycling, golf and motor sports.
