Read this interesting article we found:
Below are common symptoms associated with each eye problem.
Nearsightedness: Blurred vision that's worse when you are looking at distant objects suggests that you may be nearsighted, or myopic. People with myopia often have very good near vision.
Astigmatism: Blurry vision can occur at any distance and usually coincides with discovery of other vision problems.Farsightedness: Blurred vision that's present when you are looking at near objects or, more commonly, near and far objects indicates that you may be farsighted, or hyperopic.
Retinal detachment: An abrupt onset of flashing lights, often in combination with black floating spots in your vision, possibly combined with the sensation of a dark curtain or veil blocking a portion of your vision, suggests retinal detachment. Cover each eye separately and compare the sight in each eye.
Color blindness: Difficulty distinguishing shades or intensity of color may suggest a color perception problem. Color vision defects are usually not known to the patient until discovered on testing, and it is mainly a condition of males. If present in a female it may represent ocular disease and an eye doctor should be consulted.
Night blindness: Difficulty distinguishing objects in dim light is a sign of possible night blindness.
Cataracts: Because cataract development is usually a gradual process, your first symptom may be trouble passing the vision test when renewing your driver's license, or it may be identified during a routine eye exam. Common symptoms include:
- Hazy vision that might be worse in bright light
- Weaker vision at night; difficulty in discerning movements, details, or objects (especially street signs)
- Blinding or uncomfortable glare from automobile headlights or bright sunlight
- A need for brighter light for reading
- Colors appearing faded or yellowed
- Unexpected improvement in near vision as distance vision worsens (cataracts alter the focusing power of the lens)
- Double or triple vision (overlapping images) in one eye only
- A milky white or opaque appearance to the normally dark pupil (advanced case)
- Painful inflammation and pressure within the eye (very advanced case)
