Three Early Warning Signs of Glaucoma(Kala Motia) You Should Never Ignore

Glaucoma is one of the leading causes of irreversible blindness worldwide, yet many people don’t realize they have it until significant vision loss occurs. Because symptoms often develop slowly, glaucoma is commonly known as the “silent thief of sight.”

During World Glaucoma Week, it is important to spread awareness about recognizing the early warning signs of glaucoma and taking preventive steps to protect eye health.

Glaucoma occurs when increased intraocular pressure damages the optic nerve, which connects the eye to the brain. If left untreated, the damage can lead to permanent vision loss. The good news is that early detection and proper eye care can slow or prevent vision damage.

Here are three early warning signs of glaucoma you should never ignore.

1. Gradual Loss of Peripheral Vision

One of the earliest symptoms of glaucoma is the gradual loss of peripheral (side) vision. This type of vision loss usually occurs so slowly that many people don’t notice it until the condition has progressed.

People often describe this as tunnel vision, where the field of vision becomes narrower over time.

Healthy Habit That Helps

Routine eye checkups are the best way to detect glaucoma early. Eye specialists can measure eye pressure and optic nerve health, helping diagnose the disease before noticeable vision loss occurs.

Experts recommend getting comprehensive eye exams every 1–2 years after the age of 40.

2. Frequent Eye Pressure or Persistent Headaches

Some individuals with glaucoma may experience eye pressure, discomfort, or headaches around the eyes. These symptoms can sometimes be mistaken for eye strain or fatigue, especially for people who spend long hours using digital screens.

While not everyone with glaucoma experiences pain, persistent eye pressure should never be ignored.

Healthy Habit That Helps

Practicing good screen habits can support eye comfort and overall eye health.

Try the 20-20-20 rule: Every 20 minutes, look at something 20 feet away for at least 20 seconds.

This simple habit relaxes eye muscles and helps reduce strain from prolonged screen exposure.

3. Seeing Halos Around Lights

Another early symptom of glaucoma can be seeing halos or rainbow-colored rings around lights, especially at night. This occurs due to pressure changes in the eye that affect the cornea and fluid drainage.

People may notice this symptom while driving at night or looking at bright streetlights.

Healthy Habit That Helps

Maintaining overall health plays an important role in protecting vision.

Helpful habits include:

• Eating foods rich in vitamins A, C, and antioxidants

• Staying physically active

• Maintaining healthy blood pressure

• Avoiding smoking

• Managing diabetes if present

Why Early Detection of Glaucoma Is Critical

Early detection is the most effective way to prevent severe vision loss from glaucoma. Once optic nerve damage occurs, it cannot be reversed, but early treatment can slow the progression of the disease.

During World Glaucoma Week, eye care professionals worldwide encourage people to get their eyes checked and educate others about glaucoma symptoms.

Protecting your eyesight starts with awareness, prevention, and regular eye examinations.

Conclusion

Glaucoma often develops silently, but recognizing early warning signs can make a huge difference in protecting your vision.

If you notice symptoms like loss of peripheral vision, persistent eye pressure, or halos around lights, it is important to consult an eye specialist immediately.

Taking simple steps today can help preserve your eyesight for the future.
