Misconceptions About Eyesight

Carrots are good for your eyes;

Well, not exactly. A healthy diet is certainly good for keeping your eyesight, and vegetables like carrots should be part of this. But once you eyesight is fully functional it cannot get any better. A poor diet will damage your eyes; good diet significantly helps keep the eyesight you have.

Vision loss cannot be treated.

There is always something to improve partial vision. Glasses, contacts, orthokeratology treatments at night, laser surgery for some conditions. Talk to you doctor and optometrist.

The Sun cannot hurt your eyes

UV light form the Sun can certainly have a negative impact over time. More than 50% of pensioners have cataracts, many of which could have been prevented with proper protection. Protect your eyes with UV sunglasses.

Reading in dim Light can damage your eyes.

There is no evidence for this; dim light is just inconvenient. As we get older we need brighter light as contrast tends to fade, but that is the natural process of aging.

Sitting too close to the TV will damage eyes.

Again, it doesn’t seem to do any permanent harm, though it has no real benefits either. Sitting too close to TVs or computer monitors can cause tiredness; there might be some heath issues with radiation, but this seems unlikely.

The wrong prescription of glasses will damage eyes.

Partly true. Children under 6 can suffer poor eye development if the prescription is wrong; this should be immediately attended to if the child show evidence of poor vision. For most other people the wrong glasses will cause poor co-ordination, tired eyes, and run the risk of serious accidents, but not really damage the eyes directly. If you suspect the prescription is wrong then contact a Sydney optometrist.

Glasses will cure learning disabilities.

Not really. Poor vision can cause learning problems and be misdiagnosed as a learning disability, but it is not really a learning disability, it has simply been mistaken for one. An exception to this is that some dyslexics seem to benefit from tinted glasses, but this unrelated to the eyes focusing and is still controversial

Contact your Sydney CBD optometrist if you have any concerns about eyesight for you or you family.

Why Clean Teeth

dental-care It is too easy to neglect dental health. People prefer the aftertaste of the last meal to the strong taste of toothpaste. Some people claim not to have the time to brush their teeth; but the few minutes spent brushing your teeth each day prevents most dental problems and the discomfort of serious dental procedures later on. A study once showed that the most successful people in life were the ones who tolerated short term inconvenience over long term problems. Brushing your teeth is an example of this.

More than Just Brushing at Home

Even with regular brushing and flossing individuals should have a dental check-up every 6 months. Early detection can prevent permanent damage to teeth and gums and avoid costly and uncomfortable treatments latter on. Problems like tooth decay are often accompanied by at least some pain or physical signs of change, and should be checked straight away. But problems such as gingivitis are not obvious of painful at first, making regular check-ups essential.

Regular dental cleaning, recommended every six months, not only removes plaque, tartar, bacteria and other problems, it also makes teeth feel smoother by polishing them. This in turn helps them stay clean as bacteria are less inclined to stick to them.

Food

The advice your grandparents gave about healthy eating is probably not too far from the truth. Vegetables, dairy foods, apples and other forms or healthy eating make all the difference to one’s dental health. Green teas also seems to help teeth and breath considerably.

Sticky food and anything acidic tends to be very harmful. This includes obvious culprits such as soda and sugar, but also a few healthy foods like orange juice. It is less about the amount consumed than the regularity of consumption. Harmful food eaten several times a day is worse that a greater amount of harmful food consumed in one sitting.

Chewing gum that is sugar free can be beneficial for teeth, though the artificial sweeteners used in the gum can have their own health issues. Patients experiencing drowsiness, insomnia of other issues should consult an allergy specialist.
