Our eyes are a window to the world. They help capture life’s beauty and memories. Conditions like glaucoma and cataracts can cloud that view in different ways. Decoding the difference between glaucoma and cataract can help you care for your vision and know when to seek treatment.

What is Glaucoma?

Glaucoma is an eye condition that gradually damages the optic nerve. The optic nerve is the part of the eye responsible for transmitting visual information to the brain. This damage is often caused by an increase in eye pressure. Although some people can develop glaucoma even with normal eye pressure. Glaucoma progresses slowly in most cases, especially for open-angle glaucoma, and may not show early warning signs. This is why it is often called the “silent thief of sight.” In India, glaucoma is a significant cause of blindness, affecting millions of people. Those over 40, with a family history of the condition, diabetes, or prolonged use of steroids are at a greater risk. Common glaucoma symptoms include headaches, blurry vision, seeing halos around lights, and gradual loss of peripheral (side) vision. If left untreated, glaucoma can lead to irreversible vision loss. While there is no cure, early diagnosis and glaucoma treatment can help control its progression. Eye drops, medications, and, in some cases, laser treatments or surgery are used to lower eye pressure and protect vision. Regular eye exams are essential to catch glaucoma early, especially for those at higher risk.

What is Cataract?

A cataract is a common eye condition that causes the clear lens inside the eye to become cloudy, making it difficult to see clearly. The lens focuses light onto the retina. This is essential for sharp vision. However, with age or certain health factors, this lens can lose its transparency, causing blurred or dimmed vision. Cataracts are particularly prevalent in India, especially among older adults. Other factors like diabetes, prolonged sun exposure, smoking, and excessive alcohol intake can increase the likelihood of developing cataracts. Unlike glaucoma, cataracts usually don’t cause pain or immediate vision loss but develop slowly over time. Cataract symptoms include blurry or double vision in one eye, sensitivity to bright lights, and faded colours. The primary cataract treatment is surgery, where the cloudy lens is replaced with a clear artificial lens. This procedure is very common, safe, and effective, often taking only 20-30 minutes. Regular eye exams and protecting your eyes from UV rays are simple steps to help slow cataract progression.

Both glaucoma and cataracts affect vision, but they impact the eyes in very different ways. Understanding the difference between glaucoma and cataract symptoms can help you recognise the ailment early and choose the right course of action for eye health. While cataracts mainly cause cloudy vision, glaucoma can lead to permanent vision loss if not treated promptly.
