What is 20/20 Vision? How can I increase my eye health?

I’m sure you’ve heard of the term 20/20 vision, but did you know that is a measure of visual acuity and that it is a notation now used only in North America? Here in Australia and New Zealand we use a 6/6 notation.

But what do all the numbers mean?!

These figures are based on letter charts which are used in the standard sight test, such as the Snellen chart. The top number refers to the distance at which the chart is viewed – 20 feet (or six metres) – and the bottom number refers to the distance at which a person with ideal vision can see a letter clearly. Thus, if you have 20/40 (or 6/12) vision then you will just be able to see something from a distance of 20 feet that a person with perfect eyesight will be able to see from 40 feet.

I don’t have normal vision anymore; can I restore it naturally?

There’s no denying that it is quite a hot topic among people to discuss whether or not eyesight can be restored naturally. By naturally, I mean not using lasers, drugs, contact lenses or glasses. Correcting eyesight naturally has to do with using eye massage, relaxation techniques and eye exercises regularly. However, these techniques may only have limited success and generally only work on a small number of people.

What steps can I take to keep my eyes healthy?

Answers may vary among the eye care profession, however there are six easy steps you can take to improve and maintain your eye health.

  1. Eat Well. Good eye health starts with the food on your plate.
  2. Quit Smoking. If you’ve tried but not succeeded, try and try again.
  3. Wear Sunglasses. Even though it may not be sunny out, sunglasses protect from glare too. A pair that blocks both UVA and UVB rays are best, with wraparounds protecting from the sides and polarised sunglasses helping with glare protection.
  4. Use Safety Eyewear. If you use hazardous materials in your workplace or home, then you should always protect your eyes with the right gear.
  5. Look Away from the Computer Screen. Take regular breaks from your computer. Whether it be walking away or simply looking away from your computer for 20 seconds, all of these actions add up to better eye health.
  6. Visit Your Eye Doctor Regularly. That’s me. Be sure to come visit us at The Eye Place so we can ensure your eye care plan suits your needs.

Eating right to protect your sight …

Since we were kids, our parents have drummed into us that carrots are good for our eyes, but did you know a diet rich in nuts, fruit and vegetables helps too? Some other foods you can include in your diet to help with your eye health include:

  • Green leafy vegetables like spinach, kale, and collards;
  • Salmon, tuna, and other oily fish;
  • Eggs, nuts, beans, and other non-meat protein sources;
  • Oranges and other citrus fruits or juices;
  • Oysters and pork.
