There are a number of interesting facts as well as other logical assumptions many of which have little or no basis in fact. We have all been told at some time, “You will hurt your eyes if you do that!”, but do you really know what is or is not good for your eyes? From eating carrots to watching TV, here’s the lowdown on some vision facts and old wives tales. Test yourself with the following Myths and Facts, and see how much you know about your vision.
Eye Care Myths
Fact: Totally untrue. Optometrists are health professionals who can diagnose a lot of health conditions (including diabetes, high cholesterol, high blood pressure, stroke, cancer, liver disease and more) through a routine eye checkup. Also, many eye diseases do not have instantly noticeable symptoms. In glaucoma’s case, by the time you notice it’s effect, you can no longer recover the vision you have already lost. All this can be prevented by regular check ups with an Optometrist. Click here to book an eye-test with RAMBOD Optometry.
Fact: It is possible for two blue-eyed parents to have a child with brown eyes but it is very rare. Likewise, it is possible for two brown-eyed parents to have a child with blue eyes, although this is also uncommon.
Fact: Brown-eyed people are more common in warmer environments. It is the sunshine and its UV light that damages the eyes rather than the eye colour.
Fact: It is estimated that around 7-8% of boys have some degree of colour blindness, whereas less than 1% of girls are colour blind.
Fact: The eye is not fully formed at birth and continued to grow as you do. It is this growth that partially accounts for refractive changes that occur during childhood and make it necessary to correct a prescription (through glasses or contact lenses).
Fact: Reading frequently causes no degradation of vision. The worst thing that can happen from reading too often is headaches and eye-strain.
Fact: There has been no scientific evidence to prove this. The worst that can happen is that eye muscles will strain after trying to focus from a short distance. A rest is sufficient to help the eyes recover.
Fact: Staring at the computer for long periods won’t harm the eyes but is not advised. Similar to reading or watching television for long periods of time, the eyes will blink less than normal. This makes the eyes dry giving the feeling of eye strain and fatigue. It is recommended to take frequent breaks.
Fact: Carrots are rich in Vitamin A, an essential ingredient that replenishes the nutrient intake the eyes require to function to the best of its ability. Vitamin A also plays an important role in the protection for the eyes.
Fact: One of the biggest factors about sight conditions is that it is genetic. There may be a few external factors as well, but poor eye sight is mainly a genetic inheritance determined by genes.
Fact: This is only true for children as their vision and eyes have still not fully matured. For adults, wearing the wrong prescription at worst can lead to eye strain and possible headaches. However, it will not damage your eyesight.
Fact: Wearing spectacles does not make your eyes dependent on them. Your eye vision (short-sightedness and long-sightedness) will change over time. It changes at different rates depending on the person, therefore some people do not require glasses. The biggest factor for this (but not limited to), is due to genetics.
Contact Lens Myths
Fact: Contact lenses is just a temporary solution to help aid vision the same way spectacles do. Both glasses and contact lenses cannot cure sight conditions such as near-sightedness and far-sightedness.
Fact: After a brief adaptation period, most people don’t even notice they’re wearing contact lenses. For those that do experience contact lens discomfort, there are several remedies available once the cause is pinpointed.
Fact: The contact lenses of today are so advanced they even incorporate bifocal and varifocal technology. There are contact lenses for people who have astigmatism and other sight conditions. This means they’re suitable for people of all ages.
