Early symptoms of cataracts are not obvious in some patients, while others may experience mild blurriness of vision. As the lens becomes cloudier, the blurriness will gradually worsen, and symptoms such as nearsightedness, glare, and double vision may also appear. In advanced stages, some may develop glaucoma, leading to symptoms like eye pain, headache, nausea, and vomiting, and in severe cases, it can cause blindness. Cataracts are a common and prevalent eye disease and are the leading cause of blindness worldwide. The lens, an important optical component of the human eye, is normally transparent. Cataracts can form due to various reasons leading to protein degeneration in the lens, causing it to become cloudy and result in various degrees of vision loss. It is recommended that patients with cataracts regularly visit ophthalmologists and consider cataract removal surgery if necessary.
