Signs and 7's symptoms of cataracts include: 1.Clouded, blurred or dim vision 2.Increasing difficulty with vision at night 3.Sensitivity to light and glare 4.Need for brighter light for reading and other activities 5.Seeing "halos" around lights 6.Frequent changes in eyeglass or contact lens prescription 7.Fading or yellowing of colors At first, the cloudiness in your vision caused by a cataract may affect only a small part of the eye's lens and you may be unaware of any vision loss. As the cataract grows larger, it clouds more of your lens and distorts the light passing through the lens. This may lead to more noticeable symptoms.
Unfortunately, the improved vision is short-lived and will disappear as the cataract worsens. On the other hand, a subcapsular cataract may not produce any symptoms until it's well-developed.
A cataract may make light from the sun or a lamp seem too bright or glaring. Or you may notice when you drive at night that the oncoming headlights cause more glare than before. Colors may not appear as bright as they once did.
The type of cataract you have will affect exactly which symptoms you experience and how soon they will occur. When a nuclear cataract first develops, it can bring about a temporary improvement in your near vision, called "second sight."
