Difference Between Cataract and Glaucoma
Understanding the Difference Between Cataract and Glaucoma is essential for protecting your vision.

Under the expert guidance of Dr. Ruchika Kedia, many patients in Thane are able to detect these eye conditions early and receive prompt treatment to prevent long-term vision problems.
What Are Cataracts and Glaucoma?
What Is a Cataract?
A cataract occurs when the natural lens of the eye becomes cloudy. This clouding gradually limits the amount of light entering the eye, causing blurry or hazy vision. Cataracts usually develop slowly and are very common among people aged 50 and above.
What Is Glaucoma?
Glaucoma is a group of eye diseases that damage the optic nerve, often due to increased pressure inside the eye. It can cause permanent vision loss if not treated on time. Unlike cataracts, glaucoma doesn’t always show early symptoms, making regular eye check-ups important.
If you need help from a trusted eye doctor, you may consider visiting an experienced Eye Specialist doctor in Thane who can diagnose these conditions accurately.
