Our eyes deliver a major part of the sensory input our brains need to interpret the world around us. However, several diseases can affect our precious sense of sight, sometimes causing irreversible damage. Let’s explore some common conditions that lead to sight loss.

1. Glaucoma

This condition damages the eye’s optic nerve, often due to high pressure within the eye. Over time, this can lead to loss of peripheral vision and, if untreated, total blindness.

2. Age-Related Macular Degeneration (AMD)

Typically affecting older adults, AMD causes blurred or no vision in the center of the visual field, crucial for tasks such as reading and driving.

3. Diabetic Retinopathy

A complication of diabetes, high blood sugar levels can cause damage to the retina’s blood vessels, leading to vision impairment or even blindness.

4. Cataracts

Clouding of the eye’s natural lens – most commonly due to aging – can cause reduced vision and glare. Cataracts are the leading cause of blindness globally.

5. Retinitis Pigmentosa

A genetic disorder that leads to the breakdown and loss of cells in the retina, it results in difficulties seeing at night and loss of peripheral vision.

6. Optic Neuritis

An inflammation that damages the optic nerve, often linked to multiple sclerosis, can cause sudden sight loss.

Regular eye check-ups can help in early detection and management of these conditions. If you ever notice any changes in your vision, be sure to consult an eye care professional immediately. Remember, your sight is priceless, and taking proactive steps to care for your eye health can make a world of difference.
