Causes of sight loss

 

What is sight loss?

 

Sight loss is losing your ability to see well without some vision correction. However, sight loss can happen gradually (slowly over time) or suddenly. It can lead to partial vision loss or complete loss of vision.

The leading causes of sight loss in people are:

Macular Degeneration

This is caused by changes in the macula. However, the macula is the part of the eye that gives you clear, sharp vision.

Glaucoma

This is usually caused by high pressure from the fluid inside the eye. It can be caused by a clouding of the lens inside the eye.

Diabetic retinopathy

This affects people who have diabetes. It occurs when high blood sugar levels damage the blood vessels in the eyes. Diabetic retinopathy is a condition causing vision loss and blindness in people with diabetes.

It affects blood vessels in the retina, which is the light-sensitive layer of tissue in the back of the eye.

Injury

Sight loss can be caused by injuries gained on the eyes through fatal home or road accident, which then affects the eyes and can lead to sight loss if not immediately treated.

Infections

Sight loss can be caused by infections from an accident not treated on time; the injury starts to spread and sometimes worsens, leading to sight loss.

Keratitis

Keratitis, or inflammation of the cornea, is a condition that may occur more frequently in people who wear contact lenses than in those who do not. An infection or injury can cause keratitis in the eye. Symptoms include blurred vision, pain, and sensitivity to light or vision loss.

Conjunctivitis 

Also known as pink eye, conjunctivitis can cause vision loss. It is an infection or inflammation of the conjunctiva. It can also cause blurriness, redness, pain, or difficulty seeing.

Eyestrain

If a person stares at a screen for too long, they may begin to lose vision and perceive things they are looking at are blurry. This is usually temporary and can be resolved by taking time away from the screen and allowing the eyes to rest.

Practising the 20-20-20 rule can help prevent eye strain. That means a person looks away from the screen every 20 minutes, at something 20 feet away, for 20 seconds.

Corneal abrasion 

Injury to the eye can also cause sudden vision loss. Depending on how severe the injury is, this could be temporary or permanent, and treatment may vary accordingly.

Age-related macular degeneration

Age-related macular degeneration (AMD)is an eye disease that can impact a person’s central vision and a leading cause of vision loss for people age 50 and older, they begin to see a blurry area near the centre of their vision, which may increase in size over time.
