Which lens is THIN in the middle and thiCK At the edges?
A convex lens.
What lens is thick in the middle and thin at the edge?
convex lens
What is the difference between a thick convex lens and a thin convex lens?
In optics, a thin lens is a lens with a thickness (distance along the optical axis between the two surfaces of the lens) that is negligible compared to the focal length of the lens. Lenses whose thickness is not negligible are sometimes called thick lenses.
Whats the difference between thick and thin lens?
The diffrence between thick and thin lens depends on your precription for your eyes.

What is the thin transparent matter that covers the lens?
Retina

Fisher's appearance in thin water?
Fisher's appearance is a gel like lens. The lens are water plastic.
How the lens change it shape when foucsing on near objects?
the lens of our eyes is different to the lens of a magnifying glass-it can change its shape from thick to thin
How do you find radius of curvature in achromatic lens if focal length and diameter is given?
You also need to know the index of refraction. For glass, that is usually somewhere around 1.5. The Wikipedia article on "Lens (optics)" includes the "Lensmaker's equation"; usually you can use the "thin lens equation" (further down in the article) as a convenient approximation. Since for this question you don't know the radius of curvature, and the equation includes two radii of curvature (for the two surfaces), I suggest that you make one of the following simplifying assumptions: 1) Either assume that the lens has two surfaces of equal curvature (note: for the equation in the Wikipedia article, the signs would be opposite for both sides), 2) Or, assume that the lens has one flat side and one curved side.
Does fresnel lens is a convex lens?
yes...it is a plano-convex lens....wid grooves cut in it on convex side...it is very very thin as compared to a simple convex lens
What do the ciliary muscles on the lens do when they see focus on something far away?
They pull the lens to make it long and thin.
What is a colored lens made out of?
A coloured lens is made out of a thin, plastic lens that may be tinted to become different colours. The lens can be used to correct refractive error and other problems.
