Cataracts and glaucoma are among the most common eye diseases, especially with aging or in individuals with hereditary risk factors. Although they differ in nature, both can seriously impair vision if not diagnosed and treated early.
A cataract is the gradual clouding of the eye’s natural lens, leading to blurred vision, poor night vision, and increased sensitivity to light. The most effective and common treatment is surgical removal of the cloudy lens and replacement with a clear artificial intraocular lens.
Glaucoma is caused by increased intraocular pressure, which can damage the optic nerve and lead to progressive loss of vision. Treatment options include medicated eye drops, laser therapy, or surgery—depending on the stage and severity.
| Feature | Cataract | Glaucoma |
|---|---|---|
| Cause | Clouding of the eye’s lens | Elevated intraocular pressure |
| Symptoms | Gradual blurry vision | Loss of peripheral vision |
| Treatment | Lens replacement surgery | Drops, laser, or surgery |
| Risk | Curable with surgery | May lead to blindness if untreated |
If you notice blurred or cloudy vision
If you have diabetes, hypertension, or a family history of eye diseases
If you feel eye pressure or lose part of your side vision
If your vision worsens in low-light environments
