from the outside to the inside?
Cornea, iris, pupil, lens, retina
Cornea, iris, lens, pupil, retina
Iris, lens, cornea, pupil, retina
Pupil, cornea, iris, lens, retina

The correct order of the major parts of the eye from the outside to the inside is: Cornea, iris, pupil, lens, retina. The cornea is the clear outer layer that first lets light in, followed by the iris that controls the size of the pupil, which is the opening that allows light to enter the lens, where the image is focused before it hits the retina at the back.

Understanding the structure of the eye can be pivotal in fields like ophthalmology and optics. For instance, eye care professionals use this knowledge when diagnosing conditions like cataracts, where the lens becomes cloudy, affecting vision. Knowing the order helps you appreciate how light passes through the eye to create the images we see!
