what constitutes having poor vision?

Question

Is having poor night vision a symptom of glaucoma?

Answer 1

Lowered acuity: Poor vision is vision less than you would like. There are legal standards for instance in most states 20/200 is the limit for legal blindness. Poor vision can also be from restriction of the field of vision (peripheral vision). Poor vision is indicated by the best you can do with the best correction.

Answer 2

Less than 20/20: Using what is called a snellen acuity, both ophthalmologists and optometrists define normal vision as 20/20 in the us. This means that you can see the small letters on the eye chart at 20 feet equivalent. Less than 20/20, such as 20/40 means that you see at twenty feet what a perfectly sighted person could see at forty feet. The british use a 6 meter system so 6/6 is perfect vision.

Answer 3

Decreased contrast: Decrease in contrast sensitivity (CS) with conditions like macular degeneration, diabetic retinopathy or even previous optic neuritis can also play a role in poor vision. A patient could have 20/20 vision but poor contrast and have visual symptoms.

Answer 4

Nope...: ...After age of 12, vision is permanent. If you mean w/o glasses, sure- lasik or cataract surgery.

Answer 5

Depends : This depends on the cause of poor vision. Glasses for myopia/ hyperopia is one cause that can be corrected. Only a thorough eye exam can determine the cause of poor vision. Please see an ophthalmologist for evaluation and treament.

Answer 6

Depends: The cause of your decrease in vision needs to be identified before a solution can created. The most common cause of decreased vision is refractive error which can be corrected with glasses or contacts. If the decreased vision is from an eye health problem, other solutions maybe available. See your eye doctor.

Answer 7

Pigment disorder: As you would expect, albinism is caused by an abnormality in the pigmented tissues of the body. The eye has a pigmented layer, also abnormal in albinism, resulting in poor visual acuity, nystagmus, etc.

Answer 8

Depends: Depending on your problem, many treatments are available. Get an eye exam and have a great day. Good luck.

Answer 9

Possibly: Strain on eyes can definitely cause headaches; if you have poor vision but you are addressing it with glasses then your headaches are probably not related to it. Contact an ophthalmologist.

Answer 10

Anything: Headaches can come from fatigue, sleeping too much or too little, eye strain, sleep apnea, snoring, being dehydrated, having chronic sinusitis or allergies, too much caffeine or over the counter headache medication, high blood pressure or something more serious like a tumor. See your doctor and get checked.

Answer 11

Possibly: Need to get to a doctor for a thorough history and exam to determine if you should be referred to an eye specialist.
