Basically it means you can see up close just fine, but have difficulty seeing far away objects.
Nearsightedness is one of the types of refractive error of the eye, meaning the eye is unable to focus the light on the retina and it is not considered an eye disease. Nearsightedness is the most common refractive error of the eye.
What causes myopia?
- The eyeball is too long. The light rays that enter your eye focuses on a point in front of the retina instead of on the retina. It just falls short!
- The cornea or lens of the eye is too curved for the length of the eyeball.
The prescription will continue to change throughout the teens, and then stabilize between the ages of 20-30. This is why you should make sure your children get an eye exam every year. It is important that the eye has the optimal correction in their glasses as studies show if the glasses are not the proper prescription, it could actually make your nearsighted worse! Adults should get a comprehensive eye exam at least every 2 years to ensure things are stable. Having a large amount of nearsightedness also puts you at increased risk for something called a retinal detachment. This occurs when the sensory part of the eye, called the retina, detaches from its blood supply. A retinal detachment needs to be treated early or it could result in permanent blindness. The health of the retina is checked at every comprehensive eye examination, which is especially important for those at risk of a retinal detachment.
Commonly, a high quality lens such as our HOYA Phoenix lens paired with eyeglass frames is the quickest, and easiest way to correct nearsightedness. See our clinic today if you're experiencing this challenge!
