Which term refers to an inability to focus light rays uniformly on the retina?
Astigmatism: An eye condition where the eye cannot focus light uniformly in all directions resulting from an irregular curvature of the cornea, the crystalline lens, or the eye itself. Astigmatism results in mild to moderately blurred vision and/or eyestrain.
What is the term used to describe a condition in which light rays hit the lens bend again and sharply focus the image on the retina?
The process of bending light to produce a focused image on the retina is called “refraction”. Ideally, the light is “refracted,” or redirected, in such a manner that the rays are focused into a precise image on the retina.
What is the meaning of the term ciliary quizlet?

What is hyperopia?
Farsightedness (hyperopia) is a common vision condition in which you can see distant objects clearly, but objects nearby may be blurry.
What is the eye condition called when the lens focuses objects behind the retina?
Hyperopia. Hyperopia, or farsightedness, is a common eye condition. Hyperopia occurs when the light that enters the eye focuses behind the retina. In many cases, the eyeball is too short and so the focal point of light falls behind the retina.
Which of the following bends and focuses light rays on the retina?
Cornea. Light enters the eye through this clear, dome-shaped tissue. The cornea also bends light rays to help focus them.
What eye structure is transparent Biconvex and focuses light on the retina?
The crystalline lens is a transparent and biconvex structure. Along with the cornea, it helps to refract light to focus on the retina. By changing shape, the lens functions to change the focal distance of the eye.
Which term contains word parts that mean cell and clear fluid in tissue spaces?
Fluid in the spaces between tissues is called interstitial fluid, or ’tissue fluid’. This provides the cells of the body with nutrients (via the blood supply) and a means of waste removal.
What is the term for a disease of the light sensitive innermost layer of the eyeball?
Uveitis may develop in one eye or both eyes. It can affect the: Retina: The innermost layer of the eye senses colors and light and sends images to the brain.
