Cataracts waiting living in adults

Overview

A cataract is a clouding of the natural lens inside your eye. It’s like looking through a foggy or frosty window. Cataracts develop slowly over time and can make your vision blurry, dim, or less colourful.

Yes, cataracts are extremely common. By age 80, more than half of all adults in the UK have either a cataract or have had cataract surgery.

Cataracts mainly affect older adults, but they can also occur at any age due to injury, certain medications (like steroids), or health conditions such as diabetes.

Symptoms

Common symptoms

• Blurry or cloudy vision, as if looking through a dirty window
• Colors look faded or yellowed
• Glare from headlights, lamps, or sunlight that seems too bright
• Poor night vision or trouble seeing in dim light
• Frequent changes to your eyeglass or contact lens prescription

Symptoms in older adults

• Difficulty reading or watching television, even with glasses
• Needing brighter lights for close-up tasks
• Seeing halos around lights, especially at night
• Trouble judging steps or curbs

Causes

Main causes

• Aging – the natural lens becomes less flexible and more cloudy over time
• Injury to the eye – blunt trauma or puncture can cause a cataract to form soon after
• Medical treatments such as long-term use of steroid medications or radiation therapy
• Health conditions like diabetes, which can speed up cataract formation

Risk factors

• Getting older (especially over 50)
• Having diabetes
• Smoking cigarettes
• Spending a lot of time in strong sunlight without eye protection
• A family history of cataracts
• High levels of nearsightedness (myopia)

When to see a doctor

See a doctor urgently if:

• If you have sudden vision loss, eye pain, or see flashes/floaters – go to your local emergency department immediately.

Book a routine appointment if:

• If you notice gradual changes in your vision that make daily activities harder (reading, driving, watching TV)
• If an eye exam (with an optometrist or ophthalmologist) shows you have a cataract and you want to discuss treatment options

Diagnosis

A full eye examination by an optometrist or an ophthalmologist (eye doctor) can diagnose a cataract. The exam is painless and usually done in a clinic or hospital eye department.

Tests that may be done

• Visual acuity test – reading letters on a chart to measure how sharp your vision is
• Slit-lamp exam – a microscope with a bright light that lets the doctor see the front of your eye in detail
• Dilated eye exam – eye drops widen your pupil so the doctor can see the lens and the back of the eye clearly

What to expect at your appointment

You will sit in a chair and rest your chin on a special support. The doctor will shine a light into your eye and may use different lenses to get a clear view. You might feel slight pressure but not pain. The whole exam takes about 20 to 30 minutes.

Treatment

The only effective treatment for a cataract is surgery to remove the cloudy lens and replace it with an artificial one (called an intraocular lens). Surgery is generally safe and very successful. For people who are waiting for surgery, vision aids and lifestyle changes can help manage symptoms.

Self-care at home

• Use brighter lighting at home – add more lamps or use higher-wattage bulbs
• Wear anti‑glare sunglasses when outdoors, especially on sunny days
• Use a magnifying glass or large‑print books for reading
• Adjust screens: increase font size, reduce brightness, and use night mode
• If night driving is difficult, avoid it or ask someone else to drive

Medical treatments

No medications or eye drops can reverse a cataract. Surgery is the only way to remove it. Your eye doctor will talk to you about the best time for surgery based on how much the cataract affects your life, not just its size or stage.

When is surgery considered?

Surgery is usually offered when your vision problems interfere with everyday activities that are important to you – such as reading, driving, working, or socialising. It is a planned, outpatient procedure (you go home the same day) with a short recovery period.

Living with this condition

While you wait for surgery, you can adapt your environment to make vision easier. Use task lighting, label things with bold markers, and put contrasting edges on stairs and counters. Ask your eye doctor about low‑vision aids like telescopic glasses or handheld magnifiers.

Lifestyle tips

• Attend all scheduled eye exams so your doctor can track the cataract’s progress
• Let your healthcare team know if you have other conditions like diabetes or high blood pressure
• Wear sunglasses with UV protection whenever you are outside
• If you smoke, consider quitting – smoking can speed up cataract growth

Diet and exercise

A healthy diet rich in antioxidants (found in colourful fruits and vegetables) and omega‑3 fatty acids may help slow cataract progression, but it will not stop or reverse it. Staying active and managing your weight can also help control conditions like diabetes that increase cataract risk.

Mental health and emotional wellbeing

Living with blurry vision can be frustrating and sometimes lead to feelings of isolation or depression. It is normal to feel anxious about surgery or about losing your independence. Talk to your doctor or a counsellor if you are feeling down – there is support available.

Prevention

It is not possible to prevent cataracts entirely, especially those caused by aging. However, you may be able to slow their development by wearing UV‑blocking sunglasses, eating a healthy diet, avoiding smoking, and keeping conditions like diabetes well‑controlled.

Screening programmes

Regular eye examinations are the best way to detect cataracts early, even before they cause noticeable symptoms. Ask your optometrist how often you should have a check‑up based on your age and health.

Complications

If left untreated

• If a cataract becomes very advanced, it can cause significant vision loss and eventually blindness in the affected eye
• Very mature cataracts can become hard and swell, sometimes causing increased pressure inside the eye (glaucoma) or inflammation
• Delaying surgery for a long time may make the operation more complex

Long-term outlook

Cataract surgery is one of the most common and successful operations in the world. The vast majority of people have much better vision afterwards and can return to their normal activities within a few weeks. Even if you have waited a long time for surgery, the results are almost always very good. Your eye doctor will work with you to find the right timing and care.
