What is a Cataract?
What is a cataract?
A cataract is a cloudiness or opacity in the focusing system of your eye, the lens. Cataracts are normal as we age but can also develop from other causes such as trauma and certain medications such as steroids.
When we are young, the lens is clear like a glass of water. As we get older, it is like a little bit of milk being added to this glass, and things start to get cloudy or foggy. Eventually it reaches a point where Dr. Penny or Dr. Cornelson cannot make your glasses any stronger and the cloudiness is impacting your daily life. You may not be able to read or drive your car safely. When cataracts interfere with your daily activities and wellness, that is when you will be referred to see a cataract specialist. Cataract surgery is generally a safe and effective procedure.
Signs and symptoms of cataracts include:
- Clouded, blurred or dim vision
- Increasing difficulty with vision at night
- Sensitivity to light and glare
- Need for brighter light for reading and other activities
- Seeing “halos” around lights
- Frequent changes in eyeglass or contact lens prescription
- Fading or yellowing of colours
