One of the main applications of cylindrical lenses is in ophthalmology, specifically, to correct astigmatic vision. When a person presents astigmatic vision, it is usually the result of a corneal deformation. An astigmatic cornea will have different focal points at different axes. It is then possible to use a cylindrical lens to change the focal point of one of the axes to overlap the second one.
2 . Laser Line Scanning
This is a technique that is used to capture the shape of a 3D object into a digital copy. It is particularly useful in manufacturing, prototyping, landscaping, and architecture. This scanning technique measures the deformation of a straight line created by a cylindrical lens when it is incident into a non-flat surface. By using cameras and triangulation, it is possible to measure the changes in the shape of our laser line and therefore estimate the shape of the object that we are measuring.

3. Laser Scanning Microscopy
They are usually used in combination with acousto-optic deflectors, where the focal point of a variable lens (the acousto-optical elements) can change its position laterally without the use of movable parts. The cylindrical lens corrects the image and helps focus the light spot onto the correct plane for laser scanning microscopy.
