Reading magnifiers are an incredibly useful tool for people suffering from conditions like macular degeneration, cataracts, or glaucoma. Some might wonder why a person would use a reading magnifier when, in essence, reading glasses simply are two small magnifiers that can be worn on one's head. But reading magnifiers can do things that glasses cannot. For example, not every text is created in the same size, and advanced reading magnifiers allow you to adjust the magnification to match everything you read. Some can magnify a text up to 25 times its original size.

With a large magnifier (e.g. for reading books and maps) hold the magnifier part way between your eye and the object. Now move the magnifier very slowly backwards and forwards until you have the best image, not too small, not too fuzzy. The idea with the largest reading magnifiers is to sit up straight, sit comfortably, you should not have to bend over the magnifier and peer closely (essential for navigating in a car, you need to glance down at the map and glance up at the road signs).
The Nimrud lens: Whatever its origin, as ornament, as magnifying lens or part of a telescope, the Nimrud lens is the oldest lens in the world. Looking at it evokes mystery and wonder. It can be seen in room 55 of the British Museum, in case 9 of the Lower Mesopotamian Gallery. However unusual this object seems at first, it is not unique. In fact there are several hundred reported lenses now on record from around the ancient world.
