Causes of Cataracts

Do you have trouble seeing up close? you may possibly have hyperopia. But it may also be presbyopia. Truth be told, they are both similar, but have different causes. Because they are foundationally different, their treatment options will also vary.

Hyperopia, or farsightedness, occurs when the light rays that enter the eye do not focus directly on the retina, but in fact, they focus behind it. This is caused when the eyeball is shorter than it should be. People can have hyperopia at any age. Some childred will actually outgrow this condition, as they grow, so do their eyes. But if they do not, corrective lenses such as contacts of eyeglasses can be used to treat hyperopia. For mild hyperopic corrections some readers can be of assistance. Laser surgery, such as LASIK, is also an option.

Presbyopia has a similar visual effect in that people have trouble seeing clearly up close, but unlike hyperopia, it is age related. It is caused by the crystalline lens, inside the eye, actually hardening with age. The visual effect is very much like hyperopia; difficulty seeing up close. In general, this is corrected with lenses. reading glasses , worn only when viewing things close up, are the most common treatment. A popular option with contact lenses is called monovision, where one eye is corrected for near vision only and the other eye will have clear distance vision. Monovision wearers must train their eyes to adapt to a new way of viewing things up close and far away. Contact lenses come in a multifocal variety, correcting vision similar to progressive eyeglasses.

Hyperopia is not inevitable, and it can be treated surgically. Presbyopia has effected humans for generations, anyone over forty generally gets it, but it was never treated with surgery until very recently. When the lens inside the eye loses its ability to flex and adjust focus, seeing up close is extremely difficult, that is when it is time for treatment. Even though there are surgical options available for presbyopia, the majority of people still choose a simple pair of readers. They are a safe, stylish option that anyone can use. If losing your clear close vision due to presbyopia is a foregone conclusion, you may as well be fashionable when doing so.
