Contact lenses "give partial sun protection"

Contact lenses "give partial sun protection"

By Alexa Kaczka

Contact lenses provide a degree of protection for eyes against the rays of the sun.

This is the information given by Alison Johnson in a Newport News article that appeared in the Baltimore Sun.

She explained that contact lenses do shield part of the eye against sunshine, but added that they are not enough on their own.

People should wear sunglasses as well as contact lenses and about 20 per cent of light ought to be let in by the lenses.

Sunglasses need to block at least 99 per cent of the UV-A and UV-B rays, as well as most of the high energy visible radiation ones.

Light-coloured eyes are especially vulnerable and Ms Johnson warned against choosing sunglasses simply on grounds of cost.

She noted that some experts believe grey lenses to be the best colour for sunglasses.

Patti Wood recently told the London Free Press that glasses-wearers should ensure their frames fit properly if they want to maintain a youthful look.

She said that people can get stylish spectacles and suggested that they are worn high up on the face to let one"s eyes show properly.
