What causes errors of refractions?

What causes errors of refractions?

Imperfect eyes: An error in refraction is imbalance between the amount of light-bending (refraction) an eye needs and what it has. A perfectly refracted eye bends the light the exact amount to focus on the retina. Most eyes are not perfect and need to lessen (in nearsightedness) or increase (in farsightedness) the amount of bending. This is done with glasses, contacts or surgery. ...Read more

What are causes of infrequent or lack of eye blinking?

Uncommon: The blink rate goes down with concentrated attention such as computer work. No blinking at all is pathologic and will cause corneal opacitification due to dryness. That could be due to lid trauma with scarring or neurologic damage (rare). Blinking is automatic and not really under conscious control for more than a few moments. ...Read more

What are the causes of blurriness in glaucoma?

The visual information it sends to the brain is not as crisp since some of the "wires" within the nerve are lost. It is similar to a television cable that has been paritally cut, causing the t.V. Image to be less sharp. ...Read more

What are the causes of eye floaters?

Floaters: A posterior vitreous detachment causes floaters. This is a situation where the vitreous(jelly) of the eye detaches (not a retinal detachment), it then "crumples" up leaving dots, spots, strands of blurry vitreous; i.e. The "floater". You should have an exam to ensure the incident did not tear the retina, which could lead to a retinal detachment. Wait one year then consider surgery. ...Read more

This means that your eyes have always been farsighted but you have been able to compensate by focusing your eyes. As the focusing has decreased with age, you can no longer compensate. Glasses is the answer. ...Read more

What causes very rapid decline in vision to the point of needing glasses for astigmatism and farsightedness?

See an eye doctor. : Well, lots of things cause vision loss but the fact it seems correctable is good. You should see a eye doctor to really see for sure but, given your age, the two most likely culprits are cataracts and presbyopia.

Presbyopia, or aging of the lens, is most likely and necessitates reading glasses and sometimes distance glasses. ...Read more

I've got farsightedness. Now what?

Optical help: This is a refractive state of the eye in which a magnifying type lens in a spectacle will give you clear focus. It is a little bit misnamed as the natural lens can correct it for a while but when the lens loses its ability to compensate, it will show up. Contact lenses can help also and many are eligible for lasik. Your ophthalmologist can sort this out for you. ...Read more
