Without the right information, it is possible to go for many years without considering changing our prescription glasses believing that we can still see perfectly with our old lenses. Unknown to many people, their old eyeglasses are already working against them in terms of fatigue and eyestrain because the glasses should have been replaced.
So, how often will you need new prescription glasses?
When You Optometrist Advises
According to the American Optometric Association, adults and children above six years old should go for regular eye examinations at least once every two years provided they do not have risks of poor vision. This will be most likely be the time their eye doctor would recommend to change their eyeglasses having examined the old eyeglasses.
It is possible that you can see at least normally with your current eyeglasses, continuing to use an outdated prescription may cause you undue eyestrain. Note that prescription changes subtly over time; and continual use of an outdated prescription, believing you can still see perfectly, would strain your eyes to see adequately.
You may be straining your eyes without noticing because the eyes naturally try to focus on the items you want to see in order to see correctly. But when you notice that you are often squinting or you get frequent headaches or neck aches, it is possible that you are straining your eyes. Then, you need to change your eyeglasses.
Changes in Technology
The technology used to make your eyeglasses continues to improve every year. New designs are made every year to cater to your vision needs. You need to contact your optometrist to get state-of-the-art lenses to meet your needs, primarily if you work long hours staring at a computer screen or when you change your PC.
If there are scratches, noticeable damages, or signs of wear and tear on your eyeglasses, your doctor may recommend new prescription glasses. The older your pair of glasses is, the more likely it is that you need a new pair of eyeglasses.
On the average amount of time, you need new prescription glasses every two years, although some people get it every year. All the damages to your glasses, changes in technology, wear and tear, and other unforeseen changes in your condition would be adequately catered to under the two-year timeframe.
To have the best vision you need, get your vision examinations done every year and check if your new vision requires new prescription glasses as well.
