3. What Is Difference Between Focal Lenses And Computer Lenses?
If I talk about the focal eye lenses, these are either concave or convex and are meant to rectify your focal point so as to make the image be visible to you clearly by changing its focal length, but if I talk about the computer lens, These are not meant to make us see something clearly but are instead designed to make us view computer screen without making our eyes get damaged with the rays that the computer screen emits.
