Common Symptoms

A cataract doesn’t come abruptly as a huge mass that covers the lens. It starts out as a small cloud that has only a little effect on your vision. Regardless of the type, the most common symptoms of cataracts include:

  • Blurry vision
  • Colors appear to be faded
  • Headlights, sunlight, lamps, and other artificial lightings seem to glare more than before
  • Poor vision at night
  • Appearances of halos occur sometimes
  • Eyeglasses or contact lenses prescription constantly changes
  • Double vision in one eye happens sometimes

Types of Cataract

There are at least 4 types of cataracts based on the affected part of the eye.

  • Congenital cataract – This type of cataract occurs even during the developing years of a child either due to some genetic factors, intrauterine infection, and trauma.
  • Nuclear cataract – This type of cataract usually starts as a nearsightedness eye disorder, mistakenly thought of as a good case for having a good reading vision. But over time, this can progress and turn your lens to be cloudy yellow or brown, making it more difficult to distinguish colors. This mainly affects the center of the lens.
  • Cortical cataract – This type of cataract usually affects the edges of the lens. It begins as whitish opacities on the outer edge of the lens, and slowly progressing towards the center, blocking the light that passes through.
  • Posterior Subcapsular cataract – This type of cataract usually forms behind the lens where the light directly passes. It usually interferes with the reading vision and usually progresses faster than other types.


Cataracts usually affect older people. But, as the technology advances and the exposure to blue light, which is a common contributor to damages in the retina have become prevalent, anyone from all walks of life can develop such eye problem.

The symptoms of cataracts are noticed gradually by anyone who is exposed to eye-damaging factors. Some of these factors that can cause cataracts include genetic disorders, other eye problems which may contribute to cataracts, past eye surgery, aging, and medical conditions such as diabetes and hypertension.

Prevention Tips

A cataract is the most common eye disorder that is related to aging. To prevent early onset of a cataract or to slow its progression, one should:

  • Choose a healthy diet which is rich in fruits and vegetables as these are rich in antioxidants that are responsible to protect the cells of your eyes from oxidative stress.
  • Wear sunglasses to protect the eyes from the harmful UV rays of the sun.
  • Treat or manage health problems or injuries that may contribute to the development or the progression of cataracts.
  • Quit smoking and limit intake of alcoholic beverages as these have long-term effects to the body, which can cause chronic illnesses, which can increase the risk of cataracts and even other eye problems.
  • Most of all, have your eyes checked regularly to detect cataracts while they are still small or in their early stages.
