if you are using A+ it is lens
A lens does not reflect light. The purpose of it is to let light IN. Think of glasses. If they reflected light, people with glasses would not be able to see.
a transparent material
Not really, for the volume of the bubble is air, not a material of different refractive index. But if you were to fill a transparent balloon with water, say, you would have a lens. Try it with a clear soda bottle.
a lens is a transparent material that refract slight in a particular way.

name of a transparent and convex shaped lens
If it is perfectly transparent, nothing. It can refract and reflect the light. For example, a lens is made of glass which is transparent. The important properties are the refractive index of the material and the angle that light hits the object at.

It's called a concave lens.
The biconvex transparent structure that focuses light on the retina is called the lens.

No, you wonder around blindly all day. Nah, kidding. Yes, they are made of clear, transparent material that is smooth and easily fits to your eye. After a while you don't even notice they're in.
