It is very easy to differentiate between convex lens and concave lens. You just need to know how can you tell and recognize the difference in both. For this purpose, you must have some knowledge of physical objects. Or you must have read Physics. Or you should know the basic science. There is not a very significant difference in both of them.
The difference between them is very slight. So if you want to know that either the lens you're watching is a convex lens or it is a concave lens you should observe the following properties in them.
Convex lens is a lens which has the surface that curves or bugles outwards. So if you see that a lens is curving outward. You must have no doubt about it that it is a convex lens.
Similarly, if you see a concave lens, it has the opposite characteristics of convex in shape. So if a lens is curving in the inner surface of a sphere it is called concave lens. And you can recognize it without touching it. It is very easy. Just give it a try. I hope you've understood it very well. And now you can differentiate between both of them very easily.
