The rods ... (check all that apply)
are best for viewing detail
are located in around the periphery of the retina
require more light than the cones
are used for detecting motion in the periphery
exist in three types: short, medium and long
The cones ... (check all that apply)
are best for viewing detail
are located only in the periphery of the retina
require more light than the rods
are used for detecting motion in the periphery
exist in three types: short, medium and long
The fovea is
where the optic nerve attaches to the eye
an area of densely packed rods
an area of densely packed cones
the back of the eye where the rods and cones are located
The optic disk is
where the optic nerve attaches to the eye
an area of densely packed rods
an area of densely packed cones
the back of the eye where the rods and cones are located
Visual acuity is
the ability to adjust to light levels.
the ability to detect changes in contrast.
the ability to detect detail.
the ability to focus light on the retina.
Accommodation is
the ability to adjust to light levels.
the ability to detect changes in contrast.
the ability to detect detail.
the ability to focus light on the retina.
The retina is
where the optic nerve attaches to the eye
an area of densely packed rods
an area of densely packed cones
the back of the eye where the rods and cones are located
A eye that focuses light in front of the retina is
myopic
hyperopic
presbyopic
astigmatic
