Nearsighted And Farsighted: What Does It Mean?
By Essilor News
Nearsighted and farsighted individuals have opposite problems when it comes to vision. When you're nearsighted, your ability to see is better if an object is very close. For instance, reading a book is easy but reading a road sign isn't. If you're farsighted, you see really well when an object is at a great distance - which explains why you may need reading glasses but are cleared to drive without them.
What correction is needed for nearsighted or farsighted individuals?
These individuals have no trouble reading or seeing objects relatively close to their eyes. Whether someone needs eyeglasses, contacts or corrective surgery depends on their individual lifestyle and driving rules for vision set by individual states. Glasses for nearsighted individuals may also be required or necessary for occupations ranging from fashion designers to firefighters.
If someone is using glasses to correct nearsighted vision, the amount of times his/her glasses are worn may vary based on the severity of his/her condition. For instance, some may only need their glasses for driving but can watch TV, go to movies, and do everything else fine without them. Others may barely be able to see objects 10 feet away.
With farsightedness, individuals can be vision-problem free in younger years, yet develop a need for glasses as they age. Farsightedness is also called hyperopia, and most of the time, the eyeball is shorter than it should be, making it difficult for light coming in to the eye to focus directly on the retina.
For some people, hyperopia is caused by an abnormally shaped cornea or lens instead. Unlike presbyopia, hyperopia is not age-related.
No matter where you get your eyeglasses from, getting the right prescription is a must. Wearing glasses with the wrong prescription can cause headaches, dizziness and possibly nausea. Far-sighted patients also have options for contacts and refractive surgery for correction.
It's possible to have some degree of nearsightedness and farsightedness together. Luckily the same corrective measures are available to these patients, too. The only decision everyone should make universally is to get their eyes checked regularly.
It's important to get a comprehensive eye exam yearly, not only to keep a prescription up to date but to be screened for eye diseases and take proper preventative or treatment measures.
