Cataract
catarats
A cloudiness or loss of transparency of the lens of the eye is usually due to cataracts. Cataract surgery is done to remove the cloudy material and restore vision.
The lens is also known as the aquula (Latin, a little stream, dim. of aqua, water) or crystalline lens. http://en.wikipedia.org/wiki/Lens_%28vision%29
The lens in our eye is 10x and it's a concave lens. When the light goes through it, the light bends.
The type of microscope that you are looking for is known as a "compound microscope."A pair of lenses includes the objective lens (one or more) and the eyepiece lens.
They are curved transparent materials that make light rays come together or spread out.or a lens is a transparent material which has one or more surfaces curved for the purpose of deviating light raysA lens is an optical element that can transmit and refract light, by converging or diverging the beam. Simple lens is a single optical element. Compound lens is an array of simple lenses having a common axis.

Cataract surgery is the surgical process for replacing the lens of the eye that has developed a cataract. The natural lens is replaced with a synthetic intraocular lens with a normal lens transparency. Anesthetics are used to make the entire process painless.
The ocular lens used for nearsightedness is known as a diverging lens. It is also known as a concave lens.
Presbyopia
A concave lens is otherwise known as a diverging lens.
The condition is called presbyopia.phacosclerosis
The eyepiece can also be referred to as the lens system or lens
A converging lens is also known as a magnifying lens. The shape of the lens is a double convex shape.
The lens and cornea must be transparent so light can enter and images can be produced through electrical impulses.
EF lens are a very popular thing in cameras. The most well known camera that uses such method of lens is the Cannon EF Lens Camera introduced in 1987.
