June is Cataract Awareness Month, so we are taking this opportunity to answer common questions our optometrists often receive about cataracts.
What are cataracts?
This common condition affects more than 2.5 million Canadians and is the leading cause of treatable blindness in the world.
Cataracts are typically an age-related condition that progressively clouds the eye’s lens, which reduces vision in the affected eye. The eye’s lens comprises protein fibres, and as we age, the protein fibres form clumps causing cloudiness. If left untreated, it can cause blindness.
How can I tell if I have cataracts?
The changes in your vision will happen gradually, so you may not notice symptoms developing at first. But as the clouding of the lens becomes denser, you’re likely to experience some signs, like:
- Blurred, dim or reduced vision, making it difficult to make out details or colours
- Changes to the colour of the pupil – it may look white
- Difficulty seeing in low light or at night
- Sensitivity to light
- Seeing a ‘halo’ around bright lights
How can I prevent cataracts?
Unfortunately, there hasn’t been any study to show that cataracts are preventable. But, there are ways to slow the progression, for example:
- Regular eye exams. Your optometrist can detect early signs of cataracts; therefore, yearly eye exams are recommended for early diagnosis.
- Limit your UV exposure. When outdoors, wear quality sunglasses that protect your eyes.
- Avoid smoking and alcohol.
- Eat plenty of leafy greens and add supplements like omega-3 and turmeric to your diet.
Are cataracts treatable?
Surgery is the answer. This is a painless procedure with a short recovery time during which the eye’s lens is swapped out for a new artificial one.
