The density and location of the cataract determine the amount of vision affected.
Cataract
Loss of transparency of the lens is commonly known as cataracts. It causes vision to become cloudy or blurry, leading to difficulty seeing clearly. Cataracts can worsen over time but can be treated with surgery to remove the clouded lens and replace it with an artificial one.
Vision loss among the elderly is a major health care problem. Approximately one person in three has some form of vision-reducing eye disease by the age of 65. The most common causes of vision loss among the elderly are age-related macular degeneration, glaucoma, cataract and diabetic retinopathy.

There are a number of tests to determine when surgery is required for cataracts. The most important distinction is whether vision loss is due to cataracts or something else, such as macular degeneration or glaucoma. If you have macular degeneration or glaucoma, that doesn't necessarily mean you shouldn't have cataract surgery, it just means there might not be a huge improvement.
There are a good deal of things that can cause eye problems. To name a few... Cataract is the clouding of the eye's lens. Symptoms include double vision, diminished vision, poor vision in bright light, and decrease in sensitivity to color. Glaucoma causes pinching of blood vessels in the eye. Symptoms include eye pain, loss of peripheral vision, headache, nausea, loss of vision, and seeing spots, floaters, or flashes of light. Retinal Detachment is just as it sounds: the retina detaching from the eye. Symptoms include diminished vision, floating spots and light flashes, and segments of the visual field disappearing.
The most common side effect is pain after the procedure. A common risk of CCT is hypotony.retinal detachment, inflammation of the iris, cataract formation, macular edema, and swelling of the cornea.Loss of visual acuity, including total vision loss.
30 50 is considered mild vision loss, or near-normal vision.
Answer #1:presbyopia======================Answer #2:The clouding of the lens of the eye, either with age or in response to certainexternal influences, is called 'cataract'."Presbyopia" is the progressive loss of the ability to focus on nearby objects.
I RECENTLY WENT TO MY NEUROLOGIST CONCERNING PERIPHERAL VISION LOSS IN MY LEFT EYE FOR ABOUT AN HOUR. PRIOR TO THE VISION LOSS i HAD PAIN IN BOTH EYES. MY DOCTOR TOLD ME THAT IS WAS PROBABLY FROM A MIGRAINE EVENTHOUGH I NEVER GOT A MIGRAINE BEFORE OR AFTER THE VISION LOSS. SO THAT IS AT LEAST ONE REASON. I ALSO HAVE MULTIPLE SCLEROSIS WHICH IS AN AUTOIMMUNE DISEASE. I WAS DIAGNOSED WITH MS AFTER HAVING OPTIC NEURITIS. OPTIC NEURITIS IS AN INFLAMATION OF THE OPTIC NERVE. I ASSUMED THE VISION LOSS I RECENTLY HAD WAS DUE TO THE MS BUT MY DOCTOR DIDN'T THINK SO.
Ferrets are know to have poor eyesight and are very adaptable to vision loss. A vision impaired ferret may be easily startled and react by biting, so you need to approach them gently.
The first symptoms, a loss of night vision followed by a loss of peripheral vision, usually begin in early adolescence or young adulthood.
