Sight Direct Launch An Impartial Guide To Lenses

Finding the right pair of sunglasses can be as simple as picking them from a stand in a shop. However, many of us who enjoying bringing out our stylish ‘sun specs’ do not necessarily consider the impact and effect of the lens type and colour. With this in mind, Sight Direct, the leading providers of sunglasses, ski goggles and sports prescription sunglasses, has launched this guide to help you make the right choice.

Lens Types

Glass Lenses: These tend to be harder to scratch and offer greater clarity than plastic lens. However, glass lens are much easier to break than their plastic counterparts and tend to be thicker than plastic lenses.

Plastic Lenses: These tend to be lighter in weight and are more impact-resistant, making them a better choice for children, active adults, sportswear and safety wear. Plastic lenses also reduce harmful ultraviolet (UV) rays better than glass. Other significant advantages include versatility and durability.

UV Protection: All of the sunglasses available from Sight Direct provide 100 per-cent protection from harmful UV rays. Without this protection, ultraviolet radiation can cause serious eye problems.

Polarised Lenses: The main advantage of polarised lenses is to reduce glare from reflective surfaces such as snow or wet roads. This is achieved through polarised filters in the lenses.

Lens Colour

Grey Lenses: These ensure natural colour and offer protection in all weather conditions.

Brown Lenses: These warm colours enhance both depth and contrast, offering a good level of protection in all circumstances. These lenses are particularly popular with golfers, as they filter out blue light and therefore reduce the impact of the sky on the horizon of the drive.

Yellow Lenses: These enhance contrast in fog or low light conditions and are therefore ideal for driving purposes.

Blue or mauve lenses: Both stylish and fashionable, these lenses provide adequate protection in moderate sunlight conditions.

Pink or Red Lenses: These lenses are ideal for night-time use or in instances of low light.

Green Lenses: These allow vision very close to natural human eyesight and are therefore the best lenses for precision sports, such as golf.
