During the early stages, cataracts have little effect on vision. As the cataract progresses, symptoms may include:
Symptoms may vary depending on the part of the lens that is affected.
Nuclear Cataracts. Cataracts of the lens nucleus are most commonly associated with aging. Symptoms include:
Cortical Cataracts. Cortical cataracts usually start on the outside of the cortex (the outer area of the lens).
Posterior Subcapsular Cataracts. Posterior subcapsular cataracts typically start near the center of the back part of the capsule surrounding the lens. These cataracts often advance rapidly. For many patients, major impairment of eyesight, including near-vision problems and glare, develops within several months.
