What is concave lenss?
concave lense is a piece of smooth glass that is thick from the edges and thin from centre and is used to diverge light rays.
What kind of lenss do you need in your spectacles or contact lenss?
Depends on the type of defect of the eye
What do humans use lenss for?
as a piece of glass or other transparent material, used to converge or diverge transmitted light, to form optical images, as for magnification or correcting defects of vision
How many lenss are in a compound light microscope what is the function of the lenss?
The simplest optical microscope is the magnifying glass and is good to about ten times (10X) magnification. The compound microscope has two systems of lenses for greater magnification, 1) the ocular, or eyepiece lens that one looks into and 2) the objective lens, or the lens closest to the object.

Wearing contact lenss in lab is dangerous because?
contact lenses are made of a plastic plasma. When exposed to certain chemicals, directly though splash etc, or through gaseous atmosphere, the plastic plasma can revert into its original state. This causes the the lense to contract, tearing the surface of the eye. Do not do this in any circumstances as you could lose your sight.
