vision problems

The human eye is a complex organ responsible for vision, consisting of multiple interconnected structures. This anatomical diagram illustrates the key components of a healthy eye alongside common abnormalities, specifically focusing on cataracts. The detailed cross-sectional view helps medical professionals and patients understand both normal eye structure and potential vision problems.

This medical illustration presents a side-by-side comparison of a normal eye structure and an eye affected by keratoconus, a progressive eye disease. The detailed cross-sectional views highlight the key anatomical differences, particularly focusing on the corneal changes characteristic of keratoconus.

This detailed anatomical illustration presents two views of the human eyeball, focusing on the complex network of extraocular muscles that control eye movement. The diagram shows both lateral and frontal perspectives, highlighting how these muscles work together to enable precise eye positioning and movement in all directions.
