Four Common Myths About Eyesight Damage and Vision Correction (Guest Post)
Posted by Michelle A. Mabalod on Friday, May 03, 2013
There are many myths and 'old wives' tales' about little things you can do or not do in terms of improving your vision over time. Unfortunately,many people are still following these little rules to live by even though the great majority have been shown to be nothing but myths.
The fact remains that if you find yourself frequently engaging in one of these activities, they might cause damage to your eyesight. In addition, it probably also means that you already require vision correction in the form of glasses or contact lenses!
See some of the most common eyesight myths below. Find out what it really means if you constantly remind yourself not to engage in such actions.
Myth #1: Squinting will permanently damage your vision.
Although it is a definite sign that you need vision correction, squinting will not permanently damage your eyes.
Excessive squinting can cause strain in the face and neck, as well as in the eyes. This may cause some degree of eye pain but this is only a temporary pain which will eventually fade if the squinting stopped. Ophthalmologists who were consulted in a comprehensive study concerning eyesight myths say that squinting is actually indicative of a 'refractive error'. In other words, it indicates nearsightedness or farsightedness. It is a manner of decreasing the size of the pupil to 'let in less light' and 'further enhance your focus.' Another way of accomplishing this same effect is to wear eyeglasses!
2. Looking at a computer screen for too long will permanently damage your eyes.
This activity will certainly tire the eyes but it will not permanently damage them. Some ophthalmologists comment that the eyes become too dry when focused at a short distance for too long. This can be worsened by the fact that eyes will feel strained when focused at one distance for an extended period of time.
For people who experience this, they should take breaks and focus on something distant at least once every hour when working at a computer screen. If using a computer on a daily basis is giving you headaches, it might be more related to a pre-existing sight problem, which reading glasses might help to alleviate some stress on the eyes.
3. Wearing eyeglasses too much will cause eyes to become weakened.
The only thing not wearing eyeglasses will do is prevent the person from seeing correctly in the present. The prescribed eyeglasses should also be updated regularly by a qualified eye care professional.
For many people whose eyes get worse over time, they would have experienced this deterioration anyway. People worry about becoming 'dependent' on their eyeglasses, but they forget that the brain prefers clear vision. This leads people to wear their eyeglasses more often. Gradually, their eyes will become accustomed to the eyeglasses.
4. It is only necessary to visit the eye doctor when vision impairment becomes severe.
Approximately 75% of adults wear glasses or contact lenses. It is estimated that the majority only require slight vision correction for activities like reading or driving at night.
Eyes are used during daytime every day, and a person experiencing poor vision becomes accustomed to the vision impairment over time. It is often after their vision is corrected that the person realises how much they were missing! A regular eye check-up is done every two years. If you haven't been for a check-up for your eyes in the last two years, it is an excellent idea to have your eyes checked and start seeing clearly for yourself.
Remember, where the eye myths end is where good vision begins!
