Cataract symptoms. You can get cataracts in one eye or both eyes—but they can’t spread from one eye to the other. In the beginning, you might not have any cataract symptoms. In particular, you ...
A cataract is a cloudy area in the lens of the eye that leads to a decrease in vision of the eye. [1] [7] Cataracts often develop slowly and can affect one or both eyes. [1] Symptoms may include faded colours, blurry or double vision, halos around light, trouble with bright lights, and difficulty seeing at night. [1]
Childhood cataracts are the primary cause of childhood blindness. [4] Childhood cataracts make up 7.4% to 15.3% of blindness in kids. [4] The prevalence of childhood cataracts ranges from 0.63/10,000 to 9.74/10,000 children, with a median of 1.71. [6] This is dependent on factors like economic status but not gender or laterality.

Early symptoms may include strong glare from lights and small light sources at night and reduced visual acuity at low light levels. [ 3 ] [ 4 ] During cataract surgery, the cloudy natural lens is removed from the posterior chamber, either by emulsification in place or by cutting it out. [ 2 ]
As with cataracts not associated with glassblowing, symptoms typically have a gradual onset. Initially, people generally are unaware they have cataracts. Blurry vision is one of the first symptoms to appear which gradually worsens as the cataracts develop further.
Early symptoms of cataract may be improved by wearing appropriate glasses; if this does not help, cataract surgery is the only effective treatment. [4] Surgery with implants generally results in better vision and an improved quality of life : however, the procedure is not readily available in many countries.
Some infants are born with congenital cataracts, and environmental factors may lead to cataract formation. Early symptoms may include strong glare from lights and small light sources at night and reduced visual acuity at low light levels. [4] [5] Couching (lens depression) was the original form of cataract surgery, and was used from antiquity.
Hypomyelination-congenital cataract syndrome is a rare autosomal recessive hereditary disorder that affects the brain's white matter [1] and is characterized by congenital cataract (or cataracts that begin in the first two months of life), psychomotor development delays, and moderate intellectual disabilities. It is a type of ...
