Why Do Glasses Take So Long To Make?

In this article, we’ll be looking at the role of a lens technician in the production of glasses and why it takes so long to make a pair of glasses. To begin with, let’s look at what lenses are and how they work.

Lenses are pieces of transparent material that can be placed in front of your eye to refract or bend light rays onto your retina. This allows you to see an image clearly.

There are two types of lenses; single vision and bifocal lenses. A single vision lens is made from one piece of material that has been ground into shape, while a bifocal lens contains two sections, one for distance vision and one for reading or close-up tasks.

The process of making a lens starts with raw materials such as glass or plastic being ground into shape on a lathe machine. This is then heated up until it becomes soft enough for it to be formed into the correct shape by hand. The edges are then polished until they’re smooth enough for them not to scratch your cornea when worn. After this process has been completed, the lens is coated with an anti-reflective coating which reduces glare from light sources such as computer monitors or sunlight while wearing them.
