- A transparent material bound by two surfaces, of which one or both surfaces are spherical, forms a lens. This means that a lens is bound by at least one spherical surface. In such lenses, the other surface would be plane. A lens may have two spherical surfaces, bulging outwards. Such a lens is called a double convex lens. It is simply called a convex lens. It is thicker at the middle as compared to the edges.
- Similarly, a double concave lens is bounded by two spherical surfaces, curved inwards. It is thicker at the edges than at the middle. A double concave lens is simply called a concave lens.A lens, either a convex lens or a concave lens, has two spherical surfaces. Each of these surfaces forms a part of a sphere.

Explanation:
The correct answer is option C, which states that both statements 1 and 2 are correct. Let's understand the statements one by one:
Statement 1: A transparent material bound by two surfaces, of which one or both surfaces are spherical, forms a lens.
This statement is correct. A lens is a transparent material that refracts light to form an image. It is bound by two surfaces, which can be either flat or spherical. When one or both surfaces of the lens are spherical, it forms a lens.
Statement 2: A lens, either a convex lens or a concave lens, has two spherical surfaces.
This statement is also correct. A lens can be either convex or concave in shape. In a convex lens, both surfaces are curved outward (spherical), while in a concave lens, both surfaces are curved inward (spherical). So, both types of lenses have two spherical surfaces.
Conclusion:
Both statements 1 and 2 are correct. A lens is formed by a transparent material with one or both surfaces being spherical. Additionally, all types of lenses, whether convex or concave, have two spherical surfaces.
Summary:
In summary, a lens is formed by a transparent material with one or both surfaces being spherical. A lens can be either convex or concave, and both types have two spherical surfaces. Therefore, both statements 1 and 2 are correct.
