Does cataract cause vision loss?

Cataracts cause decreased vision in patients and are one of the leading causes of blindness. In the early stages of cataracts, patients may experience double vision, photophobia, and myopia. As lens opacity worsens, vision deteriorates significantly, affecting the patient's daily life and work. In advanced cataracts, liquefaction of the lens may occur, potentially leading to lens cortex blocking the anterior chamber angle, resulting in elevated intraocular pressure and secondary glaucoma. It is recommended to seek medical evaluation and treatment as early as possible to prevent disease progression.
