Changes in the environment have made the need for sunglasses more acute in recent years.
This is the statement made by Dr Robert Welshans, an optometrist, to the Parkersburg News and Sentinel.
He explained that as the ozone layer has thinned, there is less natural protection against UV rays and that experts say this may be aggravating problems such as cataracts.
As a result, Dr Welshans believes that it is more important than ever to wear proper sunglasses that protect against UV rays.
Not only do sunglasses help protect the eyes from the damaging effects of the sun, but they reduce glare, meaning that people squint less.
This in turn can help to prevent wrinkles from forming.
Lori Kennedy Stewart recently wrote an article for StarNewsOnline in which she explained that contact lenses offer a degree of protection against the sun.
But she explained that sunglasses are still needed as they cover a greater surface area.
