Our eyes are sometimes referred to as the windows to the soul—but they’re also windows to our overall health. Ophthalmology, the medical specialty of eye and vision care, is a vital part of enabling individuals to live better, clearer, and healthier lives. Whether you’re weighing LASIK surgery, dealing with chronic conditions such as glaucoma, or simply attempting to learn what an ophthalmologist does, this guide has you covered.
Let’s embark on a friendly, educational journey through the domain of ophthalmology—what it is, how it benefits, and when to consult an expert.
What Is Ophthalmology and What Do Ophthalmologists Do?
Ophthalmology is the branch of medicine concerned with the eye’s anatomy, physiology, and diseases. Ophthalmologists are medical physicians (MDs or DOs) who are specially trained to:
Diagnose and treat eye ailments
Perform eye surgery
Prescribe and fit glasses and contact lenses
Manage vision and eye complications of other systemic diseases (such as diabetes or high blood pressure)
While optometrists and opticians are not licensed to do so, ophthalmologists can do surgery and treat advanced eye diseases.
Interesting fact: Much systemic illness such as diabetes, high blood pressure, and even brain tumors may first present during a simple eye exam.
Ophthalmologist Treated Eye Conditions
The most prevalent reasons patients go see an ophthalmologist are as follows:
Cataracts: Clouding of the lens in the eye treatment with Cataract surgery
Glaucoma: Increased pressure in the eye that harms the optic nerve treatment with Eye drops, laser surgery
Macular Degeneration: Disintegration of the central area of the retina treatment with Injections, supplements
Diabetic Retinopathy: Destruction of the blood vessels within the eye by diabetes treatment with Laser treatment, injections
Refractive Errors: Nearsightedness, farsightedness, astigmatism treatment with Glasses, contacts, LASIK

Advances in Ophthalmology: What’s New in 2025
Ophthalmology is leading some of the most promising advances in medical technology. Some of these breakthroughs are:
Gene Therapy for Inherited Retinal Diseases
FDA-approved medicines such as Luxturna now assist in the treatment of rare genetic disorders that lead to blindness (FDA.gov).
AI-Powered Diagnostic Tools
AI algorithms are now able to identify diabetic retinopathy and other retinal diseases with excellent accuracy, even in remote clinics (Nature Medicine).
Smart Contact Lenses
Businesses are creating lenses that track blood glucose and release medications—goodbye, diabetics, to needles!
Minimally Invasive Glaucoma Surgery (MIGS)
Newer methods make for quicker recovery and less risk of complications.
When to Visit an Ophthalmologist?
You don’t need to wait until something goes wrong. Here’s when to schedule that eye exam:
Older than 40: Annual checkups are advised to watch for age-related issues.
Family history: If glaucoma, cataracts, or retinal diseases run in your family.
Digital strain: If you’re using screens all day and notice blurry vision or headaches.
Chronic illnesses: People with diabetes or hypertension need regular eye screenings.
Sudden symptoms: Floaters, flashes of light, or sudden loss of vision = urgent visit.
Thinking About LASIK or Cataract Surgery?
You’re not alone! These two surgeries are two of the most prevalent eye surgeries globally.
LASIK
Best for: Nearsightedness, farsightedness, and astigmatism
Procedure time: ~15 minutes per eye
Recovery: Most resume normal activities in 24–48 hours
Cataract Surgery
Best for: Cloudy or blurry vision caused by aging
Procedure: Replacement of lens with clear artificial lens (intraocular lens or IOL)
Recovery: Significant improvement within days
More than 3 million cataract surgeries are conducted annually in the U.S. alone—with a success rate of more than 98%.
Eye Health in Numbers
1 in every 3 individuals over age 65 has some type of vision-compromising eye disease.
80% of worldwide vision loss is deemed preventable or treatable.
Digital Eye Strain (DES) impacts more than 50% of individuals who spend more than 6 hours a day on screens.
