Age-related cataracts

When to seek medical advice

You should see an optician if you have any of these symptoms:

• your eyesight is blurred or misty
• you find lights too bright or glaring
• you find it harder to see in low light
• colours look faded

If you wear glasses, you may feel your lenses are dirty and need cleaning, even when they don't.

Cataracts aren't usually painful and don't make your eyes red or irritated, but they can be painful if they're in an advanced stage or if you've got another eye condition.

Testing for age-related cataracts

Your optician will do a series of eye tests, including a visual acuity exam, which measures how well you see at various distances.

If your optician thinks you have cataracts, you may be referred to an eye specialist (ophthalmologist) for more tests and treatment.

Treating age-related cataracts

If your cataracts aren't too bad, stronger glasses and brighter reading lights may help for a while.

But cataracts get worse over time, so you'll eventually need surgery to remove and replace the affected lens.

Surgery is the only treatment that's proven to be effective for cataracts.

Driving and cataracts

If you have cataracts, it could affect your ability to drive.

You must tell the Driver and Vehicle Licensing Agency (DVLA) if you have cataracts in both eyes.

You don't need to tell the DVLA if you have cataracts in only one eye, unless you:

• also have a medical condition in the other eye
• drive for a living

If you drive a bus, coach or lorry, you must inform the DVLA if you have cataracts in one or both eyes.

For more information, read about cataracts and driving on the GOV.UK website.

What causes age-related cataracts?

It's not entirely clear why we are more likely to develop cataracts as we get older, but some things may increase your risk of cataracts, including:

• a family history of cataracts
• smoking 
• diabetes
• eye injury
• long-term use of steroids
• drinking too much alcohol
