Eyesight myths

eye myth blog

There are a lot of myths about our eye health, so I decided to dig in and find out, how true these actually are the the do’s and don’ts of eye health?

So here are some myths I have found and the links to my findings.

Myth number 1: Carrots will help you see in the dark

This old wives tale was born in world war 2, the Air Ministry issued press releases stating that British pilots were eating lots of carrots to give them exceptional night vision.  These press releases were made to trick the Germans, preventing them finding out that Britain were using radar to intercept bombers on night raids. It also fooled the British people.

Myth number 2: Reading in bad/dim lighting will damage your eyes

Reading in dim light will tire your eyes quicker, it can cause eyestrain but unlikely to cause any long term damage.  Using lighting that comes from over your shoulder may cause glare, so it is best to use a light that shines directly onto the page.

Myth number 3:  Eye exercises will delay the need for glasses

Eye exercises can help improve your eye health, they can also help your two eyes work better together. However they will not correct eye conditions such as short-sightedness (myopia), long-sightedness (hyperopia) or astigmatism. They will also do nothing for glaucoma or macular degeneration.If practised carefully and regularly, eye exercises may be able to help delay the onset of some conditions for some people.

Myth number 4: Staring all day at a computer screen is bad for your eyes

According to Dr Blakeney, an optometric adviser to the College of Optometrists, computers will not permanently damage the eyes; however, they can cause strain or exacerbate existing eye conditions.

Eyestrain is a type of repetitive strain injury (RSI) that is caused by insufficient rest periods, incorrect working conditions.  To help prevent eyestrain, adjust the lighting so it doesn’t create a glare or harsh reflection on the screen, rest your eyes briefly every 20 minutes, and make a conscious effort to blink regularly so that your eyes stay well lubricated.

Myth number 5:  Don’t wear your glasses all the time

Glasses will not make your vision worse nor will it make your eyes dependent on the corrective lenses.

What is more likely to happen is that you will become more comfortable wearing prescription glasses because of the clearer vision they allow you. This means your day-to-day tasks and life will be easier with the added benefit of clear sight, and you won’t want to remove them as you become somewhat psychologically dependent on having that improved eyesight all the time. Fortunately, if this is the case, wearing your glasses will do no harm.
