Visual problems indicative of early cataract development include clouded, dim or blurred vision, light sensitivity, frequently changing corrective lens prescriptions and night vision issues, according to Mayo Clinic. Individuals who observe vision changes should schedule an eye exam and see a doctor quickly if double vision occurs.
People with early-stage cataracts may not realize they have vision loss, notes Mayo Clinic. When cataracts first cause clouded vision, they may affect only a tiny part of the eyes' lenses. As they grow, the cataracts distort more of the light that passes through the lenses. As the cataracts cloud more of the lenses, individuals may experience more noticeable signs and symptoms. Other visual problems include observing halos around lights, seeing colors as faded or yellowed, and experiencing double vision in one eye.
