Strong near and far accommodation in the eye requires

a healthy and properly shaped cornea and lens to properly focus light onto the retina in order to create a clear image. Additionally, the ciliary muscles in the eye are necessary for adjusting the shape of the lens to focus on objects at different distances. The ability of the eye to accommodate can be affected by age, genetics, and certain medical conditions, so it is important to have regular eye exams to ensure optimal eye health and vision.
