Truth Behind Eye Care Myths

Sunday, April 20, 2008

We have been hearing some myths about eye care from our childhood and we sometimes are guided by those. So it is very necessary for all of us to know the actual truth behind these myths to take better care of not only our eyes but also that of our children. Some of the famous doctors uncovered the truth.

Eating carrots improves my eyesight.
This is a very popular and as well as an ancient myth of eye care. This myth influences us in such a range that we often eat carrot without cooking it and think it as the best eye care. Now it is the time to look up the truth. Dr. David Kercheval, OD, of Kercheval Eye Care says that this story stems from the days when folks didn’t get enough vitamin A in their diet and needed carrots for an extra boost.

“It is a rare deficiency in the U.S., so eating a lot of carrots will do nothing but turn your skin yellow,” Kercheval said.

According to Dr. Amy Walden, OD, an optometrist for Family Eye Care at LensCrafters, lot of beta-carotene in carrots is indeed very good for eyes, but it hardly improve eye sight.

UV protected glass is not necessary for me
“You definitely need that filter,” Walden said. “Most of our glasses and sunglasses have the UV protection — and some have UVB protection to filter out rays from the sun that can cause cataracts.”

It is highly recommended even if you are a contact lens user.

Can I use my disposable contact lenses for much longer than the recommended duration.
You cannot do so. According to Walden, lens wearers who overextend their lens’ recommended lifetime are prone to infections, corneal ulcers and swelling in the cornea, and ultimately they starve the eye of oxygen. Eventually, the lenses break down and stretch to the point they no longer fit the eye properly.

“Hygiene and replacing of the lenses offer the best opportunity for eyes to do well and see well,” McCormick said.

Only those who need glasses require to go for their eye check up regularly.
Sometime we think that as we do not have glasses our eye is perfect and their is no need of regular eye checkup. But these check up not only can indicate whether you need glasses or contacts, they also screen for retinal detachment, glaucoma, cataracts and other potentially harmful conditions.

Walden said many other illnesses show up in the eyes first, including high blood pressure, diabetes and high cholesterol. Even when a person’s vision isn’t impaired, these conditions can be detected in the retina, she noted.
