concave lens factory

Description

Concave lenses have a negative curvature on one surface, so they can focus light within the lens. This means you can use them to magnify objects, which is how they're often designed. You can also use them as a bi-convex (two concave surfaces) or bi-concave lens (two convex surfaces).

This concave lens is ideal for viewing and studying small objects like insects. You may also use this lens as an aid in astronomy, where it brings the moon and planets closer to your eyes.

Concave lenses are useful in situations where you need to focus the light from one eye so the wearer can use both eyes simultaneously. These glasses enable the wearer to function well with both eyes open and maintain a clear field of vision.
