Myopia, or nearsightedness, occurs when the eyeball is too long relative to the focusing power of the cornea and lens, causing light rays to focus at a point in front of the retina, rather than directly on its surface. Presbyopia, on the other hand, is an age-related condition in which the lens of the eye becomes less flexible, making it difficult to focus on close objects. This lack of elasticity prevents the lens from changing shape to properly focus light from near objects onto the retina.
