The middle layer of the eye with a dark pigment to absorb stray light is the Blank______.Multiple choice question.ciliary bodyscleraretinachoroid

Step 1: Break Down the Problem

We need to identify the middle layer of the eye that has a dark pigment for absorbing stray light. The options provided are:

1. Ciliary body
2. Sclera
3. Retina
4. Choroid

Step 2: Relevant Concepts

• Ciliary Body: Responsible for lens shape adjustment and produces aqueous humor but does not primarily absorb stray light.
• Sclera: The white outer coating of the eyeball; it does not have a dark pigment for light absorption.
• Retina: The innermost layer, responsible for converting light into neural signals; it does not absorb stray light.
• Choroid: This layer is between the retina and the sclera, contains blood vessels and pigment that help absorb excess light.

Step 3: Analysis and Detail

Among the options:

• The choroid is rich in melanin, which absorbs stray light and prevents reflections within the eye, enhancing visual acuity.

Step 4: Verify and Summarize

Considering the purpose of each layer:

• Ciliary body: not the correct choice.
• Sclera: not the correct choice.
• Retina: not the correct choice.
• Choroid: correctly identified as the middle layer responsible for absorbing stray light.

Final Answer

The middle layer of the eye with a dark pigment to absorb stray light is the Choroid.
