What is a typical presenting symptom of posterior subcapsular cataracts?

Posterior subcapsular cataracts primarily affect the central visual axis and can lead to significant glare issues. These cataracts develop at the back of the lens and interfere with light transmission, especially in bright conditions or when there is high contrast between light and dark environments. This interference can cause the individual to experience discomfort or visual disturbances when exposed to bright lights, leading to issues with glare.

While night blindness, color distortion, and difficulty with near vision can occur with various types of cataracts, they are not the hallmark presenting symptoms of posterior subcapsular cataracts. Night blindness is more commonly associated with other conditions affecting the retina or other types of cataracts, color distortion is less specific to posterior subcapsular cataracts, and difficulty with near vision is typically seen more in those with nuclear sclerotic cataracts. Glare, therefore, stands out as a defining symptom of this specific cataract type, making it a notable concern for patients with posterior subcapsular cataracts.
