Refractive Error (Definition)

Refractive error means that you need glasses to see well. This can mean that you are near sighted, farsighted or have astigmatism. It also may be a sign that you need readers as you past the age ...Read more

What is a refractive error?

Eyeglass needs: A refractive error is the technical term for the need for eyeglass correction in all of its forms -myopia, hyperopia, astigmatism, presbyopia. Your ophthalmologist can determine your needs and supply the best eyeglass for correction. ...Read more

Is refractive error a disease?

Is refractive error a disease?

Not really: Refractive errors refer to misfocus of the eyes. With a good refraction, normal vision is restored therefore the eye isn't really diseased. ...Read more

What is meant by the phrase refractive error?

Image focus problem: Refractive error refers to nearsightedness, farsightedness, or astigmatism. If there is an imbalance between the to eyes, it is called anisometropia. These are all problems the eye has in focussing a clear image on to the retina. ...Read more

How do I find out what my refractive error is?

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

Ok I've got refractive error. What should I do?

Ok I've got refractive error. What should I do?

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.

How can refractive error relate to your 20/__ vision?

Only if uncorrected: Refractive errors mean that you have trouble focusing on what you are interested in. Once the error is corrected with glasses, contact lenses or laser surgery, you should see fine, i.e. (close to) 20/20. ...Read more

Can a person have more than one type of refractive error?

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

What is the definition or description of: Refractive error?

Refractive error: refractive error means that you need glasses to see well. This can mean that you are near sighted, farsighted or have astigmatism. It also may be a sign that you need readers as you past the age of 45 or so. ...Read more

Can refractive error make you eventually go blind?

No: 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

How severe is the refractive error in a contact lens?

None: Contact lenses do not have refractive errors, but the eye may.
Contact lenses come in different powers to compensate for the refractive error of the eye. ...Read more

Refractive error even with 20/20 vision. Is this bad for flying?

Refractive error even with 20/20 vision. Is this bad for flying?

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

Is it true that your eyeglass prescription number is your refractive error number as well?

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

What is it like when two eyes have different refractive error?

What is it like when two eyes have different refractive error?

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

What is the treatment for refractive error that is best and has fewest side effects?

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?

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?

Presbyopia: 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
45-48: +1.50
49-52: +1.75
53-56: +2.00
