Farsightedness explained

What is farsightedness ? The medical term for farsightedness is hyperopia. Farsightedness explained: People who are farsighted see things at a distance more easily than they see things up close. People can have varying degrees of hyperopia, depending on their eyes’ ability to focus on close-up objects. If you are very farsighted close objects may be so blurry that you can’t do tasks such as reading or sewing.

What causes farsightedness or hyperopia?

Two parts of the eye are responsible for focusing: the cornea and the lens. The verz1cornea is the clear front surface of the eye. The lens is a structure inside your eye that changes shape as you focus on objects. The cornea and lens work together to refract (bend) incoming light, and then to focus that light onto your retina. The retina is at the back of your eyeball. It receives visual information and sends it to your optic nerve, which carries that information to your brain.

A perfectly formed curved lens and cornea results in a perfectly focused image. Your eye you can’t focus correctly when light enters if your cornea is too flat. This causes farsightedness. You can also be farsighted if you have a shorter-than-normal eyeball. This causes light to be focused behind your retina instead of on it.Farsightedness often runs in families.It often develops in adults as the lenses of your eyes age.

Some children develop farsightedness.which often starts in early childhood. Butverz2 normal growth corrects the problem. If a child is still a bit farsighted when the eye has stopped growing (at around 9 years of age), the eye can usually adjust to make up for the problem. But as we age, our eyes can no longer adjust as well. Starting at about age 40, our eyes naturally begin to lose the ability to focus on close objects.

Farsightedness treatment options

The simplest way to correct farsightedness is to get prescription eyeglasses or contact lenses. These corrective lenses change the way light enters your eyes, helping you focus better.

Refractive surgery can also treat farsightedness. Procedures such as Laser-verz3assisted in-situ keratomileusis (LASIK) are more commonly used to treat nearsightedness. However, they can also work if you’re farsighted. LASIK uses a laser to change your cornea’s curvature. This will make the light refract correctly, projecting a focused image onto your retina.

Eye muscle exercises include conditioning, strengthening, and toning the six muscles in your eye to naturally improve you vision.
