The lens, located behind the pupil, is responsible for focusing light onto the retina. In a healthy eye, the lens is clear, allowing light to pass through and produce sharp, clear images. However, with cataracts, the lens becomes cloudy, making it difficult for light to reach the retina, which causes blurred or impaired vision.<\/span><\/p>\n<p><span style=\"color: #000000;\">If you experience blurry vision, difficulty seeing at night, or a noticeable change in vision, it\u2019s important to see an eye care professional. Early detection and monitoring can help manage cataracts, and if necessary, ensure timely surgery to restore vision.<\/span><\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-981 size-full\" title=\"cataract\" src=\"https:\/\/healthfinder.ae\/blog\/wp-content\/uploads\/2025\/08\/cataract.webp\" alt=\"cataract\" width=\"1536\" height=\"1024\" srcset=\"https:\/\/healthfinder.ae\/blog\/wp-content\/uploads\/2025\/08\/cataract.webp 1536w, https:\/\/healthfinder.ae\/blog\/wp-content\/uploads\/2025\/08\/cataract-300x200.webp 300w, https:\/\/healthfinder.ae\/blog\/wp-content\/uploads\/2025\/08\/cataract-1024x683.webp 1024w, https:\/\/healthfinder.ae\/blog\/wp-content\/uploads\/2025\/08\/cataract-768x512.webp 768w\" sizes=\"auto, (max-width: 1536px) 100vw, 1536px\" \/><\/p>\n<h2><span style=\"color: #000000;\"><strong>Types of Cataracts<\/strong><\/span><\/h2>\n<p><span style=\"color: #000000;\">There are several types of cataracts, classified based on their location or cause:<\/span><\/p>\n<ul>\n<li data-start=\"705\" data-end=\"919\"><span style=\"color: #000000;\"><strong data-start=\"705\" data-end=\"726\">Nuclear Cataracts<\/strong>: These develop in the center of the lens and are commonly associated with aging.
