Dry Eye Disease
A common condition where your eyes don't stay wet enough, either because they don't make enough tears or the tears don't work the way they should.
Tear film / ocular surfaceOverview
Your eyes stay comfortable and clear thanks to a thin layer of tears spread across the surface every time you blink. Dry eye disease happens when that tear film breaks down, either from not enough tear production or tears that evaporate too fast or aren't the right consistency. It's one of the most common reasons people visit an eye doctor, and it ranges from a mild nuisance to a condition that interferes with daily life.
Symptoms
- Stinging, burning, or a gritty, sandy feeling
- Redness and irritation
- Sensitivity to light
- Blurry vision that improves with blinking
- Watery eyes (an overcorrection when the surface is irritated)
- Trouble wearing contact lenses comfortably
Causes & Risk Factors
- Getting older, especially past age 50
- Hormonal changes, including pregnancy and menopause
- Extended screen time, which reduces how often you blink
- Windy, dry, or smoky environments
- Certain medicines, such as antihistamines, antidepressants, and some blood pressure drugs
- Autoimmune conditions like Sjögren syndrome or lupus
- Some eye surgeries, including LASIK
Treatment & Management
- Over-the-counter artificial tears or lubricating gels
- Prescription eye drops that help your eyes produce more tears
- Small punctal plugs that keep tears on the eye's surface longer
- Adjusting or switching a medicine that's contributing to dryness
- Taking regular screen breaks and using a humidifier in dry indoor air
When to contact your eye doctor
See your eye doctor if dryness is persistent, painful, or affecting your vision, or if over-the-counter drops aren't helping after a couple of weeks.
Diabetic Retinopathy
Long-term high blood sugar can damage the tiny blood vessels in the retina, leading to leakage, swelling, or abnormal new vessel growth.
Retinal blood vesselsOverview
The retina relies on a network of very small blood vessels to stay nourished. When blood sugar stays high over months and years, those vessels can weaken, swell, leak fluid, or close off entirely. In more advanced stages, the eye tries to grow new, fragile vessels to compensate, and those vessels can bleed or scar. It's a leading cause of vision loss in working-age adults, but regular screening catches it early, when it's most treatable.
Symptoms
- Often no symptoms at all in the early stages
- Blurry or fluctuating vision
- Dark spots or strings ("floaters") in your vision
- Faded or washed-out colors
- Dark or empty areas in your field of vision
- Sudden vision loss in more advanced cases
Causes & Risk Factors
- Longer duration of diabetes
- Blood sugar that stays poorly controlled over time
- High blood pressure and high cholesterol
- Pregnancy in people with diabetes
- Smoking
Treatment & Management
- Managing blood sugar, blood pressure, and cholesterol closely
- Laser treatment to seal or shrink abnormal vessels
- Injected medicines that reduce swelling and abnormal vessel growth
- Surgery (vitrectomy) for advanced bleeding or scarring
- Yearly dilated eye exams, even without symptoms
When to contact your eye doctor
If you have diabetes, get a dilated eye exam at least once a year, even if your vision feels normal — this condition is often silent until it's advanced.
Macular Degeneration
A gradual breakdown of the macula, the small central part of the retina responsible for sharp, detailed vision.
Macula (central retina)Overview
The macula sits at the center of the retina and gives you the sharp, straight-ahead vision you use for reading, recognizing faces, and driving. AMD develops when the tissue here thins and breaks down, or when abnormal blood vessels grow underneath it. Side vision usually stays intact, but central vision becomes blurred, distorted, or develops a blank spot. It's one of the leading causes of vision loss in older adults, and it comes in a slower "dry" form and a faster-progressing "wet" form.
Symptoms
- Straight lines that look wavy or bent
- A blurry or blank spot in your central vision
- Colors that look less vivid
- Needing brighter light for reading or close-up tasks
- Trouble recognizing faces
Causes & Risk Factors
- Age, particularly past 55
- Family history of AMD
- Smoking, which roughly doubles the risk
- High blood pressure and cardiovascular disease
- Obesity and a diet low in fruits and vegetables
- Prolonged, unprotected exposure to sunlight
Treatment & Management
- Specific vitamin and mineral supplements (AREDS2 formula) for some intermediate cases
- Injected medicines that can slow or stabilize wet AMD
- Low-vision aids and magnification tools for daily tasks
- Quitting smoking and eating a diet rich in leafy greens
- Using an Amsler grid at home to track changes in central vision
When to contact your eye doctor
Sudden distortion or a new blind spot in your central vision can signal wet AMD progressing quickly and deserves prompt attention.
Cataracts
A clouding of the eye's naturally clear lens that gradually makes vision blurry, hazy, or dim.
LensOverview
The lens sits behind the iris and focuses light onto the retina. It's normally clear, but proteins inside it can clump together over time, clouding small areas at first and eventually more of the lens. This is a cataract. It develops slowly, often over years, and is one of the most common and most treatable causes of vision loss — a short outpatient surgery replaces the clouded lens with a clear artificial one.
Symptoms
- Cloudy, blurry, or dim vision
- Colors that look faded or yellowed
- Increased glare from headlights or bright light
- Trouble seeing well at night
- Frequent changes in glasses or contact lens prescription
- Double vision in one eye
Causes & Risk Factors
- Aging (the most common cause)
- Diabetes
- Smoking and heavy alcohol use
- Prolonged, unprotected sun exposure
- Long-term use of corticosteroid medicines
- Previous eye injury or surgery
Treatment & Management
- Updated glasses or brighter lighting in early stages
- Cataract surgery, which removes the clouded lens and replaces it with a clear artificial lens
- Surgery is typically outpatient with a short recovery
- Wearing sunglasses to help slow further clouding
When to contact your eye doctor
Talk with your eye doctor when cloudy vision starts affecting daily tasks like reading, driving, or recognizing faces — that's usually the right time to discuss surgery.
Glaucoma
A group of conditions that damage the optic nerve — the cable that carries images from your eye to your brain — often linked to pressure inside the eye.
Optic nerve / drainage angleOverview
Fluid constantly flows in and out of the front of your eye. When the drainage angle that lets fluid out becomes blocked or inefficient, pressure builds up inside the eye and can gradually damage the optic nerve. Because this usually starts at the edges of your vision and progresses slowly, most people don't notice any change until meaningful vision is already lost — which is why glaucoma is often called the "silent thief of sight." Vision lost to glaucoma cannot be recovered, but treatment can stop or slow further damage.
Symptoms
- Usually none in the early stages
- Gradual loss of side (peripheral) vision
- Patchy blind spots in central or side vision, in later stages
- Tunnel vision in advanced disease
- In acute angle-closure glaucoma: sudden eye pain, headache, blurred vision, halos around lights, nausea — this is an emergency
Causes & Risk Factors
- Elevated pressure inside the eye
- Age over 40, with risk increasing further after 60
- Family history of glaucoma
- Certain ethnic backgrounds carry higher risk for specific types
- Thin corneas, extreme nearsightedness or farsightedness
- Past eye injury or long-term steroid use
Treatment & Management
- Prescription eye drops that lower eye pressure
- Laser treatment to improve fluid drainage
- Surgery to create a new drainage pathway in more advanced cases
- Regular monitoring of eye pressure and the optic nerve
- Consistent use of prescribed drops, since damage already done can't be reversed
When to contact your eye doctor
Get regular comprehensive eye exams, especially after 40 or with a family history of glaucoma. Sudden eye pain, blurred vision, or halos around lights need urgent care the same day.
