What is called a gradually developing cloudiness of the lens, occurring most frequently in persons over 70 years of age?

Age-related cataracts are a common condition that affects many people over the age of 70. It is a gradual cloudiness of the lens in the eye, which can lead to blurred vision and difficulty seeing. This condition is different from epilepsy, which is a neurological disorder that affects the brain and can cause seizures. Glaucoma is also a different condition, characterized by increased pressure in the eye and potential damage to the optic nerve. A heart attack, on the other hand, is a medical emergency affecting the heart and is not related to the cloudiness of the lens in the eye. Therefore, age-related cataracts is the most fitting answer for this question.
