Understanding Glaucoma: Early Signs, Risk Factors, and How to Protect Your Vision

Glaucoma is often called the “silent thief of sight” because it can cause irreversible vision loss before you even notice symptoms. This eye condition affects millions of people worldwide and is one of the leading causes of blindness. However, with early detection and proper management, vision loss from glaucoma can often be slowed or even prevented.
 

What Is Glaucoma?

Glaucoma is a group of eye diseases that damage the optic nerve, which is responsible for sending visual information from your eye to your brain. Most commonly, this damage is caused by an increase in intraocular pressure (IOP). There are several types of glaucoma, with the most common being open-angle glaucoma, which develops slowly over time.
 

The Importance of Regular Eye Exams

Because glaucoma typically has no symptoms in its early stages, regular comprehensive eye exams are essential. Many patients don’t realize they have glaucoma until significant vision loss has occurred, and unfortunately, that lost vision cannot be restored. That’s why early detection is the most powerful tool in managing this disease.
 

At Blue Lakes Eye Care, our optometrists use advanced diagnostic technology (including visual field testing, optic nerve imaging, and intraocular pressure measurements) to detect the earliest signs of glaucoma, even before you notice any changes in your vision. These tests are painless, quick, and a critical part of preventive eye care. By scheduling routine eye exams, especially if you're over 40 or have risk factors, you give yourself the best chance at preserving your vision and maintaining long-term eye health.
 

Early Signs to Watch For

Although early-stage glaucoma often presents no noticeable symptoms, there are some signs to be aware of as the disease progresses:

• Gradual loss of peripheral vision

• Blurred vision or halos around lights

• Eye pain or pressure

• Headaches
   

If you notice any of these symptoms, schedule an eye exam immediately.
 

Risk Factors for Glaucoma

Anyone can develop glaucoma, but some people are at higher risk. Common risk factors include:

• Age over 60

• Family history of glaucoma

• High eye pressure (IOP)

• African, Hispanic, or Asian descent

• Existing health conditions like diabetes, high blood pressure, or heart disease

• Prolonged use of corticosteroid medications

• Severe nearsightedness or farsightedness
   

Understanding your personal risk helps guide how often you should have your eyes checked.
 

How to Protect Your Vision

While glaucoma cannot be cured, there are several steps you can take to reduce your risk and slow its progression:

• Schedule regular eye exams: Early detection is key.

• Follow treatment plans: If diagnosed, use prescribed eye drops or medications consistently.

• Maintain a healthy lifestyle: Exercise regularly, manage chronic health conditions, and eat a diet rich in leafy greens and antioxidants.

• Protect your eyes: Wear protective eyewear during sports or high-risk activities.

• Know your family history: Inform your optometrist if glaucoma runs in your family.
