their both lenses, and you can see through them. They also have curves.
Convex bulges outward (thicker in the center than the edge)Concave bulges inward (thinner in the center than the edge)Convex lenses magnify when you look through then, concave lenses make things look smaller.You can focus a distant object to a point with a convex lens (the image will be upside down).
yes
They need a concave lens
The lenses in your eye are convex. GCSE Science by any chance? same here :( Good luck!
A concave surface curves inward. Cave-in
They are not the same. Convex lens bulge outward, and concave lenses go in ward. Convex lenses focus light, and concave lenses spread light out.
Objective lenses are convex lenses.
convex and concave

They use convex lenses because they need to focus the light IN to the eye. Convex focuses in while concave spreads the light out. So, they use convex lenses.
yes
windows if u have a old camera or binoculars,u could open them up and get the concave and convex lenses from there.
Convex lenses are curved inward. Concave lenses curve outward.
Concave lenses curve inwardly.Convex lenses curve outwardly.* See related links.

Convex lenses protrude or curve out, concave lenses curve in, like a cave...
