Protecting Your Vision

Member: My vision has been getting blurrier over time, especially when I read or drive
at night. Should I be worried it might be cataracts? — Dale, Circle Pines

Dr. Hill: This is a great question, Dale. Blurry vision can have several causes, and cataracts are one possibility. Cataracts are one of the most common eye conditions that can develop as we age, and they happen when the clear lens inside the eye becomes cloudy. This can make your vision hazy or less colorful, and it may also increase glare from lights or cause more difficulty seeing clearly at night.

But cataracts aren’t the only cause of eyesight changes over time. Other conditions — such as macular degeneration, macular edema or glaucoma — can also affect vision in different ways. That’s why it’s important to not assume the cause without a thorough exam from an eye doctor. The good news is that many eye conditions can be treated or managed if they’re caught early. To protect your vision:

•  Schedule regular eye exams, especially if you have a family history of eye disease. 
•  Get a yearly dilated eye exam if you have diabetes to help catch early signs of diabetic eye disease. 
•  Wear sunglasses when outdoors to reduce UV damage.
•   Manage related health conditions like high blood pressure and diabetes.
•   Avoid smoking, which raises the risk of many eye problems.

If you ever notice sudden changes like flashes of light, new floaters or a dark curtain over your vision, see an eye doctor right away. Early attention can make a big difference for your long-term eye health. Taking action now is the best way to keep your sight clear and comfortable for years to come.
