A cataract is a cloudy spot in the lens of your eye, the clear part that focuses light. As the lens clouds, vision turns blurry, hazy, and less colorful. Most cataracts come from normal aging: the proteins in the lens break down over time, and by age 80 more than half of Americans either have a cataract or have already had surgery to remove one, according to the National Eye Institute. The reassuring part is that cataracts are reversible. Surgery removes the cloudy lens and replaces it with a clear artificial one, and 9 out of 10 people who have it can see better afterward.
Why cataracts hit Black Americans harder
Cataracts are the leading cause of blindness in the world, and the damage is not shared evenly. In the Baltimore Eye Survey, a landmark study of blindness in East Baltimore, unoperated cataract caused 27 percent of all blindness among Black participants, and it was four times more common as a cause of blindness than among white participants. The same study found white residents were almost 50 percent more likely than Black residents to have had cataract surgery before age 80. The cataracts were not the problem on their own. The missing surgeries were.
Black Americans also develop certain cataracts more often. In the Barbados Eye Studies, cortical cataract, a clouding in the outer layer of the lens, developed more than three times as often in participants of African descent as in white participants, and overall cataract appeared about 1.8 times more frequently, the researchers at Stony Brook University reported in Ophthalmology in 2004. The National Eye Institute lists cataract, glaucoma, and diabetic retinopathy as conditions for which Black Americans carry higher risk.
The symptoms: what a cataract actually looks like
Cataracts grow slowly, so the change can feel like ordinary aging until it is well advanced. The signs the National Eye Institute lists include:
- Vision that is cloudy, blurry, or dim
- Glare and halos around lights, especially headlights and streetlights at night
- Trouble seeing to drive after dark
- Colors that look faded or yellowed
- Needing brighter light to read
- Frequent changes to your glasses or contact prescription
- Double vision in one eye
None of this is something you have to live with. If your vision is getting worse, that is a reason to get examined, not a reason to buy stronger glasses and wait.
What raises your risk
Age is the main driver, but several factors speed cataracts up, and some of them weigh more heavily on Black adults:
- Diabetes. Cataracts form earlier in people with diabetes, and diabetes is more common in Black adults, which raises exposure across the community.
- Smoking. Smokers develop cataracts at higher rates.
- Steroid medicines. Long-term or high-dose corticosteroids, including some used for asthma, lupus, and other chronic conditions, raise the risk.
- Ultraviolet light. Years of unprotected sun exposure add up.
- Past eye injury or eye surgery, and high blood pressure.
Many of these overlap with other threats to Black eye health, which is why one good exam can catch several problems at once.
Why the surgery gap exists
Cataract surgery is one of the most common operations in the United States, yet Black patients reach it later and less often. A seven-year analysis at the University of Texas Medical Branch, published in Translational Vision Science & Technology in 2023, found Black patients arrived for surgery with significantly worse vision and were less likely to have surgery within 120 days of referral, with white patients more than six times as likely to receive a premium replacement lens. A separate study of cataract care in the San Francisco Bay Area found Black patients had the lowest surgery utilization and the poorest pre-surgery vision, with Medicaid coverage and language barriers explaining much of the gap.
The gap is built from access, not biology: thinner insurance coverage, fewer referrals to a surgeon, longer travel to eye care, language barriers, and well-earned mistrust of a system that has under-served Black patients. Being told to "wait until it gets worse" plays a role too. Cataract surgery does not have to wait until you are nearly blind. When a cataract interferes with driving, reading, or working, it is reasonable to treat it. The same eye visit can screen for glaucoma and diabetic retinopathy, the two other eye diseases that hit Black adults hardest.
What cataract surgery involves
Cataract surgery is short, outpatient, and routine. The eye is numbed with drops or an injection, the surgeon removes the cloudy lens, and a clear artificial lens, called an intraocular lens, takes its place. You go home the same day. Most people notice sharper vision within a few days, and the eye finishes healing over about four to six weeks. The National Eye Institute calls the surgery safe and reports that 9 out of 10 people who have it see better afterward. The lens implant is permanent and does not cloud again.
How to get care
Start with a dilated eye exam. Drops widen the pupil so the doctor can see the lens and the back of the eye, which is the only way to catch a cataract, glaucoma, and diabetic retinopathy in the same visit. If you have diabetes or are over 60, you should have a dilated exam at least once a year. Bring your medication list and tell the doctor if vision changes are affecting your driving or work, because that affects the timing of surgery. If you want a clinician who understands the stakes for Black patients, find a Black ophthalmologist or optometrist in the directory and book an exam.
Frequently asked questions
Can cataracts be cured without surgery? ▼
No. No eye drop, vitamin, or laser reverses a cataract. Surgery to replace the clouded lens is the only treatment, and it works in about 9 out of 10 people. New glasses and brighter lighting can help in the early stages, but they do not stop the cataract from growing.
Do I have to wait until the cataract is "ripe" to have surgery? ▼
No. The old advice to wait until a cataract is advanced is outdated. When a cataract interferes with driving, reading, working, or daily life, it is reasonable to treat it. Being told to wait is one reason Black patients reach surgery later and with worse vision.
Why are cataracts a bigger problem for Black Americans? ▼
Black adults develop some cataracts more often, are more likely to have undiagnosed and untreated cataracts, and are less likely to get surgery on time. In the Baltimore Eye Survey, unoperated cataract caused 27 percent of blindness among Black participants. The driver is access to care, not the eye itself.
How often should I get an eye exam? ▼
Adults over 60, anyone with diabetes, and anyone with a family history of eye disease should get a dilated eye exam at least once a year. A dilated exam is the only way to detect a cataract, glaucoma, and diabetic retinopathy together before they take vision.
Is cataract surgery safe? ▼
Yes. The National Eye Institute calls cataract surgery safe, and it is one of the most common operations performed in the United States. It is an outpatient procedure done with numbing drops or an injection, and most people see better within a few days. As with any surgery, ask your ophthalmologist about your specific risks.
