Nothing but shape.
A lens is just a curved piece of glass, as well as glass being a straight lens. A lens bends the light while glass does not*.

A flat piece of glass. Also, any lens where the shape of the convex part matches the shape of the concave part. An example would be a flat piece of glass bent over a sphere.
A piece of glass with one or two spherical surfaces is called a lens. Lenses are commonly used in optics to refract light and focus images.
The curved glass in a camera is called a lens. The lens focuses light onto the camera sensor, allowing the camera to capture an image.

A curved transparent object may refer to a lens, such as those found in eyeglasses or cameras, or it could be a curved piece of glass like a magnifying glass or a glass vase. These objects are designed with a curved shape to focus or distort light passing through them.
A lens is a piece of curved glass that causes light rays to converge or diverge to create a focused image. Lens are commonly used in optical devices such as cameras, glasses, and microscopes to manipulate and focus light.
The curvature of a lens causes incoming light to bend or refract at different angles, focusing or diverging the light rays to create images. This bending is due to the varying thickness of the lens, which changes the speed of light passing through it. A flat piece of glass does not have the same effect on light because it does not cause the same degree of refraction or focusing.
A "lens" is "glass". However, lens glass is quite different from a drinking glass. making a lens u must consider: magnifying power clarity color transmission These features involve: getting the geometry right minimizing imperfections making the right formula with the proper additives
