What is dome magnifier?
A dome magnifier is a dome-shaped magnifying device made of glass or acrylic plastic, used to enlarge words on a page or computer screen.
How does it work?
They are plano-convex lenses: the flat (planar) surface is placed on the object to be magnified, and the convex (dome) surface provides the enlargement,they usually provide magnification more than 1.8x

Where can we use it?
Dome magnifiers are often used by the visually impaired. They are good for reading maps or basic text and their inherent 180°design naturally amplifies illumination from ambient side-light.
