What is a 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. 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 between 1.8× and 6× magnification. 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. They are suitable for people with tremors or impaired motor skills, because they are held in contact with the page during use.

Magnifier Information 



After the age of about forty you will experience a problem viewing small print and tasks involving close detail work. This eye condition is called presbyopia and magnification is the answer.



What type magnifier is best? Hand held magnifiers are best for short duration use and a magnifying lamp or hands free magnifier with stand are best for long duration use. 


Magnifier glass power and work distance: Select magnifiers with a power that will allow you to perform your task at a comfortable distance.



The higher the power of the magnifier the shorter the focal range(work distance) and the smaller the field of view. The high power magnifier may not be the best magnifier for you.
