Many variables determine the right time to remove cataracts. For instance, if cataracts cause difficulty in completing your daily routine, you may qualify for cataract surgery. Furthermore, your vision may need to meet the insurance company’s criteria. The most common sign is a slow decrease in your vision clarity. It appears as though a haze or fog develops, and it seems like you are looking through a dirty window. Other symptoms include decreased night vision, light sensitivity, faded or yellowed color appearance, double vision, and the appearance of light “halos.”
