causes of blindness

Did you know that blindness is mostly caused by age-related diseases? But, with proper awareness and precaution, you can prevent blindness. Before we proceed further, we would like to clear a cloud of thought that hovers around the word ‘blindness’. 

Blindness varies from hazy vision to completely losing sight. There are cases with a limited vision where you will be able to distinguish between objects and shapes. ‘Legal blindness’ is also a common term in which the vision is highly compromised.

7 causes of blindness

Blindness is one of the common health conditions. There are multiple reasons ranging from genetics to acquired conditions that lead to permanent blindness. For a better understanding, we have listed 7 health conditions that lead to blindness.

Age-related macular degeneration

Age-related macular degeneration generally happens in older people. In this condition, the central vision, which is necessary for performing day-to-day activities, is affected. As a result, reading, driving, and close-up vision get affected. If you have any similar conditions, please consult us right away.

Glaucoma

Glaucoma mainly occurs when the fluid in the eye builds up pressure. Regular examination through a tonometry test can reveal your intraocular pressure. And further, we can suggest you the proper treatment. The damage caused by glaucoma is irreversible; therefore, it is highly important to start the treatment as early as possible.

Diabetic Retinopathy

If you are diagnosed with diabetes, your eyes might be affected too. This is a condition where the blood vessels in your eyes get affected by high blood glucose levels. The early signs of this can be detected through simple diabetic screening tests. Be aware of your vision, as diabetes can lead to many other eye-related problems.

Cataract

A cataract is a condition where the lens of the eyes gets clouded. It can occur at any age and due to various conditions like trauma, age, medication, and even genetics too. Cataracts are one of the most common visual impairments that are causing blindness worldwide.

Trachoma

Trachoma is an eye infection caused by a bacteria named Bacterium Chlamydia Trachomatis. If your eyes catch this bacteria, there is a chance of eyelids getting scarred, and it can affect your cornea as well, gradually leading to blindness.

Corneal opacity

This is mainly caused when the cornea of the eye gets scarred. Further, it becomes difficult for the light to pass through the eye, causing the cornea to be clouded or blurred.

Uncorrected Refractive Errors

Refractive errors are quite common eye disorders that lead to blurred vision. Although this might seem usual, if left untreated, it can lead to blindness. Refractive errors cannot be prevented, but if diagnosed early, we can restore vision. It is mainly treated through corrective glasses, lenses, or refractive surgery.

Your eyesight is precious, and it is important to understand the best way to take care of your eyes. We hope that you got a brief understanding of the conditions that might lead to blindness. Please note that these are only a few common conditions we mentioned. There are various other conditions too. So, it is always advisable to get your eyes checked regularly.
