Which protein structure relays the signal after light is captured in the eye?

• Retinal

• Opsin

• Rhodopsin

• Sclera

Where is the region of highest visual acuity located in the eye?

• Macula

• Fovea

• Sclera

• Choroid

What is the function of microsaccades in the human eye?

• To capture light

• To prevent blurring by moving the focus

• To nourish cells in the retina

• To absorb excess light

What happens during Troxler Fading?

• An object in focus becomes clearer

• An object in focus fades away

• The eye captures more light

• The optic nerve sends stronger signals

What is the role of horizontal cells in the eye?

• To capture light

• To create sharper images

• To nourish the retina

• To absorb excess light

Which part of the eye absorbs excess light?

• Pigment Epithelium

• Choroid

• Sclera

• Macula

What is the function of the choroid in the eye?

• To capture light

• To nourish cells in the retina

• To absorb excess light

• To protect the eye
