What are Cataracts?
Cataracts are a common eye condition that affects millions of people worldwide. In fact, more than half of all individuals aged 60 and older are impacted by cataracts. A cataract occurs when the natural lens of the eye becomes clouded due to a buildup of protein. This clouding can occur in one or both eyes and can lead to blurred vision, making everyday activities like reading or driving difficult. Cataracts generally worsen over time, with night vision typically being the most affected. In the early stages, cataract symptoms can often be improved with brighter lighting, but as the condition progresses, surgery may be required.

Risk Factors for Cataracts
While cataracts are primarily a result of aging, several factors can increase the risk of developing them, including:

• Diabetes
• Smoking
• Obesity
• Excessive alcohol consumption
• Excessive exposure to sunlight
• Exposure to radiation
• Family history of cataracts
• High blood pressure
• Previous eye injury or surgery
• Prolonged use of corticosteroid medications

In rare cases, cataracts may also be present at birth, sometimes caused by an infection like rubella contracted by the mother during pregnancy or as a part of other birth defects.

Symptoms of Cataracts
Cataracts often develop gradually, and many people don’t realize they have them until their vision is affected. Symptoms of cataracts include:

• Blurred, hazy, or double vision in one or both eyes
• Decreased color perception
• Yellow-tinged vision
• Sensitivity to bright light
• Poor night vision
• Seeing halos around lights
• Frequent changes in eyeglass prescriptions

Treatment of Cataracts
In the early stages, cataracts can sometimes be managed with non-surgical methods, such as:

• New corrective lens prescriptions
• Anti-glare sunglasses
• Magnifying lenses
• Brighter lighting for reading or close-up tasks

However, if cataracts start to interfere with daily activities, including reading, work, or driving, cataract surgery may be necessary. Cataract surgery is typically performed on one eye at a time, usually 4 to 8 weeks apart. It is the most common eye surgery performed in Canada and is a highly effective way to restore vision.

Prevention of Cataracts
While cataracts cannot be fully prevented, their development can sometimes be delayed with the following measures:

• Wearing wide-brimmed hats to block sunlight
• Using sunglasses that block ultraviolet rays
• Avoiding smoking and excessive alcohol consumption
• Eating a diet rich in antioxidants

Although cataracts can cause significant vision impairment if left untreated, they can be successfully treated with surgery once they start interfering with daily activities. If you are experiencing any symptoms of cataracts, contact Infinity Vision Lasers to schedule a consultation.
