The term 'Parts of Eyes' refers to the components that make up the human eye. Uveas (5 letters) is the layer of tissue that surrounds the eyeball and provides nourishment to the eye. Iris (6 letters) is the colored part of the eye that controls the amount of light entering the eye. LENSES (6 letters) are transparent structures that help focus light onto the retina, allowing us to see clearly. Together, these three parts of the eye work together to allow us to see the world around us.
