Better Vision

Here’s what you need to know:

FAVOR FISH:

Regular fish consumption reduces the risk of macular degeneration, according to a study of adults aged over 49. The researchers said the protective effect was due to high omega-3 fatty acid levels in fish, which may help maintain cell membranes in the retina.

THINK ZINC:

The retina contains particularly high amounts of zinc.Pumpkin and sunflower seeds, barley, chicken, crabs and oysters are sources of this essential mineral.

SQUINT NO MORE:

Don’t forget to wear your sunglasses. too much exposure to ultraviolet light while we’re young can increase the risk of developing cataract and macular degeneration later in life. Make sure your sunglasses are UV-protected.

GET YOUR GREENS:

These foods contain high amount of lutein and zeaxanthin, two antioxidants concentrated in the macula, the portion of the retina responsible for clear vision.

STOP SMOKING:

Smokers had a 63% increased risk of cataracts, compared with non-smokers.

Cigarette smokers are more than twice as likely as non- smokers to develop age-related macular degeneration(ARMD).

EYE TESTS:

See your optometrist at least once every two years.

GIVE IN TO WEARING GLASSES:

Can eye exercises reduce your need for glasses or contact lenses? In the vast majority of cases, no. It’s better to wear glasses or contacts if they help you to achieve your optimum vision.

LOOK INTO YOUR FAMILY HISTORY:

Ask family members if they know of any relatives who had or have macular degeneration-- and especially the inherited form, macular dystrophy. If there is a family history, regular eye tests are especially important to spot the condition before permanent damage is done.

EYE STRAIN:

Many of us can feel eye strain after reading , watching TV or using the computer. While it can be bothersome, it’s generally not dangerous for your eyes. Try these tips:

1.Close your eyes to let your own tears moisten the surface of your eyes.

2.Look at a distant scene for a couple of minutes to relax the muscle inside your eye that helps you focus up close.

3.Get up, stretch, and do something else for a little while.

TEST YOUR EYE IQ:

Q: True or false: 

Each of us has a dominant eye and a non-dominant eye, similar to being right- or left- handed.

A: True. Roughly two-thirds of the population is right-eye dominant.To find your eyedness, extend both arms, then bring both hands together to create a small opening. With both eyes open, view a distant object through the opening.Then alternate closing the eyes to determine which eye is viewing the object(i.e., the dominant eye).
