Refractive Error In Children
Ophthalmologist: If you need to find this out to get glasses, you will need a prescription from your ophthalmologist. If you already own a pair of glasses an optical shop can tell you the numbers. The reading takes specialized instrumentation and you cannot find this out from things found in the non-optical environment. ...Read more
Or consider surgery: Depending on how much and what type of refractive error, glasses and contacts are good options, or you could consider surgery. Modern techniques allow correction of almost any type of refractive error, including myopia (nearsightedness), hyperopia (farsightedness) and astigmatism. More info at http://www.2020vision.

Yes: There are four types of refractive error which may occur singly or in combination: hyperopia (cannot see close), myopia (cannot see far), astigmatism (blurring at all ranges), presbyopia (inability to focus). Each of these are tested for by your ophthalmologist and glasses may be prescribed to optimize vision. ...Read more
Refractive error is simply the strength of glasses needed for you to see well.
It is the "medicine" in your glasses.
Refractive error is directly related to physical properties of your eye; how large or small, curvature of your cornea and the clarity of your lens (early cataract can affect change).
It is not a disease, and hence, it can not cause blindness. ...Read more
It depends: Refractive error limits for pilots vary by branch of service and probably also by country. In the us air force, a small amount of refractive error is permissible as long as the vision is correctable to 20/20 in each eye. For specifics, visit the medical standards website for your desired branch of service and career field. ...Read more
Refractive Error: Yes, this is typically your refractive error. When an eye doctor is comparing the numbers from other exams / doctors, he/she usually refers to the glasses prescription numbers for comparison. In higher levels of refractive error, contact lens prescriptions have be adjusted from the glasses power so the main number to know if your glasses refractive error. ...Read more
It depends: If the difference is small, the brain can usually fuse the two images, especially with the help of glasses. When it becomes very large (anisometropia), it becomes more difficult to fuse and can result in amblyopia. Contact lenses tend to be better tolerated in people with large differences than glasses. ...Read more
Depends on the cause: There are several ways to treat vision problems related to refractive errors (need for prescription correction). The easiest is to wear glasses. Contact lenses can decrease your need for glasses, but must be cared for regularly in order to prevent infections. Laser vision correction and lens replacement surgery are alternatives that can provide lasting glasses-free vision but are costlier. ...Read more
If someone has basically no refractive error, what is the normal reading glass prescription as he ages? Also do things like the dashboard get blurry?
Is the term for the loss in focusing power of the lens of the eye with aging. Yes, the dashboard may eventually get blurry. Smart phones cause more eye strain than we used to have. There can be small variations.
Age 42-44: +1.25
60+: +2.50. ...Read more
