It is a good idea visit an optometrist at least once a year for an eye examination if you are older. This will allow the eye doctor to diagnose any vision complications you have in time, making treatment much more straightforward. We at Advanced Optical in Virginia, MN, are an optometry clinic and we offer eye exams. The most common treatment for refractive errors is prescription lenses.
How Do Prescription Lenses Work?
Most vision problems are associated with light rays failing to focus appropriately on the retina. Prescription glasses and contacts work by focusing light correctly on the retina. Here's a breakdown of the eye problems that can be treated with prescription glasses or contacts.
Myopia is a vision problem where you can see close objects clearly, while farther away objects are blurry. This means you have no problem reading a book but can't read a highway sign far away.
Nearsightedness develops when the shape of the eye inappropriately refracts (bends) light rays, focusing the image not on the retina. Getting an eye exam is an most accurate way to confirm myopia. Prescription glasses and lenses compensate for the inappropriate refraction/bending of the light rays by the eyes, ensuring that the image is correctly focused on the retina. As a result, you can see close and farther away objects clearly.
Farsightedness is the opposite of nearsightedness, whereby you can see far away clearly, while close objects are blurry. You can read a faraway road sign without problem, but you have difficulties reading a book.
Hyperopia occurs when your cornea isn't curved properly, or your eyeball is improperly formed. These eye abnormalities cause light to be refracted improperly in the eye, focusing the image off ofd the retina. Prescription glasses and contacts work by compensating for the refractive error in the eye, focusing the image properly on the retina. Thereby, you can see farther away and close objects clearly.
Astigmatism is caused by the imperfection in the eye curvature resulting in blurred near and distant vision. This vision complication appears when the lens inside the eye or the cornea has a mismatched curve; therefore, the light rays aren't bent the same. Prescription glasses and contacts will help compensate for the imperfections in the eye curvature, helping to ensure light rays are bent the same, and you can see near and distant objects clearly.
Presbyopia refers to the natural gradual loss of your eye's ability to focus on near objects, which occurs as part of aging. This vision problem may start in the mid-40s and worsens in the mid-60s. Prescription glasses and contacts will allow you to see close objects clearly.
