A cataract is an eye condition characterized by the clouding of the lens inside the eye. People with cataracts usually have blurry vision, and the effect of the condition on vision is similar to looking through a frosty glass. Cataracts make reading and performing simple tasks like driving or engaging in your hobby difficult.

Most times, cataracts develop slowly, and in a few cases, it develops rapidly. If left untreated over time, it interferes with vision. Wearing eyeglasses or using stronger lighting may make dealing with cataracts easy, but you need cataracts surgery to avoid complete vision loss. Cataract surgery is safe and effective in treating cataracts, so you have nothing to worry about.

Symptoms of Cataracts

The following are common symptoms of cataracts

  • Blurred, dim, or clouded vision
  • Glare and sensitivity to light
  • Halos around light
  • Yellowing or fading of colors
  • Increased difficulty to see images at night
  • Need for stronger lightening to read and perform other activities
  • Frequent need to change contacts or glasses prescription
Cataracts Symptoms

The cloudiness most people with cataracts experience is due to covering only a small part of the lens at first. This makes most people remain unaware of vision difficulties. Still, as cataracts grow larger and cover a larger portion of the lens, it distorts the light passing through the lens to the optic nerve, leading to different symptoms.

When you should see a doctor

Ensure you schedule an appointment with your doctor if you notice any vision changes like flashes or double vision, sudden headache or pain, or double vision.

Causes of cataracts

Most times, cataracts occur due to injuries that affect the eye tissues or ageing. Sometimes, inherited genetic disorders may increase the risk of developing cataracts.

Cataracts may also result from other eye conditions, medical conditions like diabetes, or past surgery. Using steroid medications over a long period can also increase the risk of developing cataracts.

How does cataract form?

The lens is found behind the iris, the coloured part of the eyes. Normally, the lens helps to focus the light passing through the eyes, resulting in clear, sharp images formed on the retina, a light-sensitive part of the eyes. The function of the retina in the eye is similar to the film found in a camera.

Ageing causes the eyes to lose its flexibility gradually, makes the eyes less thick and transparent. Ageing and other medical conditions can make the tissues in the lens to breakdown and form clumps, which clouds parts of the lens.

The clouding in the lens becomes denser and spreads across the lens as the cataract develops. Cataracts block and scatter the light passing through the lens, preventing the formation of clear and defined images on the retina. This causes the blurred vision common in people with cataracts.

Most times, cataracts develop in both eyes but do not grow at the same rate. The cataract in one of your eyes may be more advanced than the other, causing you to have a different vision in both eyes.

Types of cataracts

  • Nuclear cataracts (affecting the center part of the lens)

This type of cataracts causes nearsightedness at first. Sometimes, it may cause a temporary vision improvement in reading vision. However, the lens will gradually become yellow, making you experience a clouded vision.

  • Cortical cataracts (affecting the outer sides of the lens)

Cortical cataracts develop as whitish, wedge-shaped streaks on the edges of the lens. As the condition slowly progresses, the streaks spread to the centre of the eyes, interfering with the light passing through the lens and causes vision problems.

  • Posterior subcapsular cataracts (affecting the back of the lens)

This cataract mostly starts as a small, cloudy area that forms at the back of the lens, where light passes the lens. The cataract affects the reading vision, causes halos and glare, and reduced vision in bright light. Posterior subcapsular cataracts usually grow faster than other types of cataracts.

  • Congenital cataracts (people who have cataracts at birth)

Some people develop this cataract during childhood or have them at birth. It may occur due to inter uterine trauma or infection or genetics. Sometimes, they result from conditions such as rubella or neurofibromatosis type 2, dystrophy or galactosemia.

Most times, a congenital cataract does not affect vision, but you can remove them if you notice any changes in your vision.
