Ocular features refer to the characteristics and structures of the eyes that contribute to vision and overall eye health. These include the cornea, iris, pupil, and retina, each playing a vital role in how we perceive light and color. The cornea is the clear front layer that helps focus light, while the iris controls the size of the pupil, regulating the amount of light entering the eye. Additionally, ocular features can indicate various health conditions. For example, changes in the retina can signal issues like diabetes or hypertension. Regular eye examinations can help detect these changes early, ensuring timely intervention and maintaining good ocular health.
