Understanding Cataracts: What You Need to Know

Cataracts are one of the most common eye conditions, yet many people aren't quite sure what they actually are. Put simply, a cataract is a clouding of the lens inside your eye. This lens, which sits behind your pupil, is normally clear and helps focus light onto the back of your eye. When it becomes cloudy, vision becomes hazier, rather like looking through a foggy window.

Most cataracts develop gradually as part of the natural ageing process. The proteins within the lens slowly break down and clump together over many years. This is why cataracts are so common in older adults. By the age of 80, more than half of people will either have a cataract or have had cataract surgery.

The symptoms tend to creep up slowly. You might notice colours appearing more faded or washed out. Bright lights may seem to have halos around them, and you might find driving at night increasingly difficult due to glare from headlights. Reading can become harder, and you may need stronger lighting than before. Some people find their distance vision deteriorating while close-up vision temporarily improves, a phenomenon sometimes called "second sight."

While cataracts can't currently be prevented or reversed through medication, the good news is that cataract surgery is one of the most commonly performed operations in the UK and has an excellent success rate. The clouded lens is removed and replaced with a clear artificial one. Most people notice a significant improvement in their vision.

Not everyone with cataracts will need surgery. In the early stages, updating your glasses prescription and using better lighting can help manage symptoms. Your optometrist will monitor any changes and discuss options when the time is right.

Regular eye examinations are essential for detecting cataracts early and tracking their progression. At Atlantic Home Eyecare, we provide thorough examinations in your own home, making it simple to stay on top of your eye health even if getting out to a high street optician is difficult. We cover a wide area across the Southwest, from Exeter to Bristol and everywhere in between.

If you've noticed any changes in your vision, or it's been more than two years since your last eye test, consider booking an appointment.
