Cataracts are not usually painful. However, they can cause discomfort by making your eyes more sensitive to light. Cataracts are a standard part of the eye’s aging process.
Eventually, they can cause:

• Vision that’s cloudy, blurry, foggy, or filmy.
• Sensitivity to bright sunlight, lamps, or headlights.
• Glare, especially when you drive at night with oncoming headlights.
• Prescription changes in glasses, including sudden nearsightedness.
• Double vision.
• Need for brighter light to read.
• Difficulty seeing at night (poor night vision).
• Changes in the way you see color.
