lense	a clear inner part of the eye known as the lens helps the cornea focus an image
Sclera	the white outer layer of the eyeball. At the front of the eye it is continuous with the cornea.
Ciliary muscles	The ciliary muscle is a ring of smooth muscle in the eye's middle layer (vascular layer) that controls accommodation for viewing objects at varying distances
Retina	The retina is a thin layer of tissue that lines the back of the eye on the inside. It is located near the optic nerve. The purpose of the retina is to receive light that the lens has focused, convert the light into neural signals, and send these signals on to the brain for visual recognition.
Optic nerve	the optic nerve is the part of the eye that transmits visual information from the retina to the brain.
Pupil	Pupil, in the anatomy of the eye, the opening within the iris through which light passes before reaching the lens and being focused onto the retina
Cornia	cornea is the first place where light passes through, and bends the light to make it focus
Iris	The colored tissue at the front of the eye that contains the pupil in the center.
Rods	rods are the part of your eye that are receptive to low light and help with night vision
cones	cones are the are the of your eye that are responsible for colour light
blind spot	a spot in their retina where the optic nerve connects. In this area there are no light-sensitive cells so this part of your retina can't see.
Astigmatisms	is a common and generally treatable imperfection in the curvature of your eye that causes blurred distance and near vision. Astigmatism occurs when either the front surface of your eye (cornea) or the lens, inside your eye, has mismatched curves
Presbyopia	Presbyopia is the gradual loss of your eyes' ability to focus on nearby objects. It's a natural, often annoying part of aging.
First light passes through the_____ and bends the light to make it focus.	cornia
Some light goes through the _______, and the ****(the coloured part of the eye) controls how much light goes through.	pupil, iris
Next, light passes through the _____ (a clear inner part of the eye). The ______ works together with the cornea to focus light correctly on the retina.	lens
When light hits the _______ (a light-sensitive layer of tissue at the back of the eye), special cells called photoreceptors turn the light into electrical signals.	retina
These electrical signals travel from the retina through the______ to the brain. Then the brain turns the signals into the images you see.	optic nerve
Myopia	or known as nearsightedness, is a condition where a person can see things clearly is they are close, but they cannot see things from far away. The eyeball is long, and the image is projected Infront of the retina. A concave Lens is how you would correct Myopia.
Hyperopia	or known as farsightedness, is a condition where a person can see things from far away, but the lack the ability to see from short distances. The eyeball is too short, and the image projected behind the retina. A convex Lens is how you would correct Hyperopia.
reflecting vs refracting	A refracting telescope uses lenses to gather light, while a reflecting telescope uses mirrors. refracting telescope was made by galileo Galilei, the reflecting telescope was made by sir issac newton
convex vs concave	A concave lens is thinner in the middle and thicker at the edges. A convex lens is thicker in the middle and thinner at the edges. A concave lens is uses to correct nearsightedness, and a convex lens is how you would correct farsightedness.
