A) Smooth and clear corneas
B) Opacity of the lens behind the cornea

D) Shattered look to the light rays reflecting off the cornea
Corneal Abrasion
A scratch or scrape on the surface of the eye's cornea, often causing significant discomfort and sensitivity to light.
Light Rays
Lines that represent the direction along which the light energy is moving.
Opacity
Lack of transparency or clarity in a material or lens, or the quality of being difficult to understand.
- Recognize prevalent ocular disorders and anomalies, including their treatment and criteria for referral.
- Apply knowledge of eye anatomy and physiology to clinical practice, including safety measures during ocular assessments.

Final Answer :
D
Explanation :
A corneal abrasion causes irregular ridges in reflected light, which produce a shattered appearance to light rays. No opacities should be observed in the cornea. The other responses are not correct.
