There are various types of cataracts, some of them are: Subcapsular Cataract – Cataracts occurring at the back of the eye lens. Nuclear Cataract – This occurs in the central zone of the eye’s lens.  Cortical Cataract – White Wedge-like opacity that starts at the edge of the eye lens but slowly works its way to the centre (Nucleus). Growing Ages – Nearly half the population by the age of 60 develops cataracts and about 80% of people get a cataract in at least one eye by the age of 70 years. Traumatic Cataract – A direct injury or trauma can cause damage to the eye leading to cataracts. It can be progressive or instantly after a trauma. Metabolic Cataract – Various disorders in body metabolism including autoimmune diseases like diabetes and galactosemia can cause cataracts over time. Secondary Cataract – In several cases, cataract develops as a result of some other primary ocular disease such as chronic eye inflammation or glaucoma. Steroid-induced Cataract – Excess intake of oral steroids or inserting steroid drops in the eye can create cataracts. It is always recommended to ask a doctor before using one.
