You need eye specialist’s recommendations to wear sunglasses

For effective protection of the eyes, sunglasses are to be worn with recommendation by a qualified eye care personnel, an Optometrist with Florida Eye Clinic, Dr. Anene Chukwuemeka has advised.

He lamented that in Nigeria there is still little or no regulation to access and make sure sun glasses meet the requirement for eye protection.
“In countries with proper regulation such as the United States of America and United Kingdom, sunglasses have specifications and has to be recommended by a qualified eye care personnel,” he said.
He said generally, sunglasses should filter out 95 – 100 percent Ultra-Violent Radiation (UVA and UVB) light rays, adding that those that meet this specification are labelled UV400.
Chukwuemeka said the sunglasses should also fit well ,close to the face  such that light does not enter through the sides or from above or below, advising that it should be gotten from trusted places through consulting an eye care practitioner if the person is in doubt.
“Sunglasses are normally tinted lenses that usually meant to block out sun rays from getting so much into the eyes and stop these rays from damaging or causing discomfort to the eyes. So in essence, sunglasses are protective eye wear,” he said.
According to him  it is good for people especially those sensitive to light to wear sunglasses when they are in the sun to protect their eyes from ultraviolet rays of the sun in particular which can cause serious eye problems such as cataracts, retina burns, pterygium and others.
He said:”People should never look at eclipse without polaroid lenses as this can damage their retina. It is most advisable for albinos to wear sunglasses because they lack dark pigments called melanin which protects against sun burns.”
He also said it is recommended for use after eye surgeries and for patients that are on some eye medications such as mydriatics.
Dr Chukwuemeka however advised that  people should not wear sunglasses in dark places or places with poor illumination as it further reduces the amount of light that enters the eye and hence lowers visual acuity of that person in that condition.
