Kinds of Magnifiers
Magnifying glasses are the most ancient optical devices that were created. As historians would say the Romans were the first to discover the magnifying glass in the first century AD. Thousands of years ago, Egyptians used chips of crystal or a shiny stone called obsidian to view smaller objects. Over the past years, a magnifier was created. The English philosopher Roger Bacon designed the first magnifier during the 13th century. Now, with the advancements in technology, magnifiers have been modified into different styles and design to accommodate the growing needs.
Gone are the days when stone and crystals were the only objects used as reading aids. Today, magnifiers are very sleek and trendy. Here is a description of some common low-vision devices that can help fix common reading difficulties and assist problems that are caused by visual impairments.

The object behind the lens appears ten times larger than its original size.
Stand Magnifiers- For people who write and read at the same time, stand magnifiers make researching easier. There is no need to hold a magnifying glass with one hand and the pen on the other.
