Cataract is a common blinding eye disease. Under normal conditions, it is transparent and light passes through it and some refractive interstitium to reach the retina in order to clearly see outside objects. Once the lens becomes cloudy for some reason, it can affect the retinal imaging and make it difficult to see. In other words, a cloudy lens that causes vision loss is a cataract. Lens clouding, which begins in middle age, increases significantly with age. Because it occurs mainly in the elderly, it used to be called senile cataract.
