What is a cataract?
Inside your eye is a natural lens that helps focus light for clear vision. A cataract happens when that lens becomes cloudy. As the clouding increases, vision can look blurred, dim, or washed out—like viewing through a foggy window.
Common symptoms
Cataracts often develop gradually. You may notice:
- Blurry or hazy vision
- Glare or halos around lights
- More light needed to read
- Difficulty driving at night
- Colors look faded or yellowed
- Double vision in one eye (sometimes)
Tip: If you notice a sudden change in vision, new floaters, flashes of light, or a curtain/shadow in your vision, seek urgent evaluation.
Causes and risk factors
Aging is the most common cause. Cataracts can also be associated with other factors, including:
- Family history of cataracts
- Diabetes
- Eye injury or prior eye surgery
- Long-term UV exposure (sunlight)
- Smoking
- Some medications (your doctor can review)
Can cataracts be slowed?
You can’t “reverse” a cataract with drops or supplements, but healthy habits may help slow progression:
Protect your eyes from UV
Wear sunglasses with UV protection when outdoors.
Don’t smoke
Smoking is linked with faster cataract development.
Manage diabetes
Good glucose control supports long-term eye health.
Keep regular eye exams
We can monitor changes and guide next steps.
How are cataracts treated?
Early on, updated glasses, brighter lighting, and anti-glare strategies may help. When cataracts start interfering with daily life—reading, driving, work, or enjoying activities—surgery is the definitive treatment.
Cataract surgery, in simple terms
During surgery, the cloudy natural lens is removed and replaced with a clear artificial lens implant (often called an intraocular lens, or IOL). Your surgeon will discuss lens options and expected outcomes.
Frequently asked questions
Will new glasses “fix” cataracts? ▾
Glasses can help early on, but they can’t remove the clouding. If symptoms progress, surgery is the fix.
When is it time to consider surgery? ▾
Typically when cataracts limit your daily activities (driving, reading, work, hobbies) or your safety. We’ll review your exam findings and your goals.
Do cataracts come back after surgery? ▾
The cataract itself does not return. Some people develop a cloudy membrane behind the lens implant months or years later. If that happens, it’s commonly treated with a quick in-office laser procedure.
