Difference Between Glaucoma and Cataracts

What is the difference between glaucoma and cataracts? Well, both glaucoma and cataracts are physical conditions that cause vision loss. When discussing glaucoma vs. cataracts, it’s important to note that although these eye conditions both cause damaged vision, they are not the same thing. As we age, the clear lens in our eyes begins to thicken and over time becomes discolored. This vision condition is referred to as a cataract. Slowly and over a long span of time depending on the person, this will result in vision loss. Now, on the other hand, vision loss in glaucoma occurs due to damage to the optic nerve, which connects the eye to the brain.

There are many distinct factors when it comes to the causes, symptoms and treatment options in both cataracts and glaucoma. We always get questions like, “Which is worse glaucoma or cataracts?” This question can be a challenge to answer as they are both conditions that can result in vision loss, so it’s important that regular eye exams are in your care routine. Here we will discuss those elements to help you have a better understanding of the eye condition and the glaucoma signs and symptoms.

  • Lens Becomes Clouded
  • Due To Age
  • Symptoms Are Slow To Develop

When it comes to cataracts, they can take many years to fully develop. Usually it affects a small part of the eye to start and slowly clumps up around the entirety of the lens. As this protein that our eye lens are made up begins to clump, it distorts the light that passes through and ultimately damages vision. This results in dim, cloudy and blurry vision that gets worse over time. Cataracts can occur in both eyes or just one.

Cataracts are the most common cause of vision loss in people over the age of 40 and is a primary cause of blindness across the world. There are over 200,000 cases a year and are typically due to age. Cataract treatment can help restore vision and if your glasses aren’t doing the trick, it may be time for cataract surgery. Of course, seeing an eye doctor is the first step as you don’t want to consider surgery unless the cataracts are interfering with your everyday life.


  • Optic Nerve Is Damaged
  • Sometimes Related To Aging
  • Symptoms Are Hard To Detect

What causes glaucoma and how do you treat it? Glaucoma is an eye disorder that damages the optic nerve that carries information from the eye to the brain. It typically relates to high pressure built up inside the eye, commonly known as ocular hypertension. When the optic nerve is damaged, there is no communication between the eye and the brain resulting in glaucoma. Unfortunately, most people notice glaucoma signs and symptoms when the disease has progressed and they have irreversible vision loss and may suffer with permanent blindness. The first signs of glaucoma are critical to keep an eye out for.

If you’re curious to know how to prevent glaucoma, well, there is no cure. It’s extremely important to see an optometrist to detect early signs and symptoms of potential glaucoma. Usually, the first symptom is often a loss of peripheral vision, also known as side vision. If you are currently affected by this, find a Tucson eye doctor near you.
