magnifying sheet

Most magnifying sheets are made of plastic and use a Fresnel-style lens; listings typically describe them as plastic or plastic Fresnel lenses.

These listings generally describe magnifying sheets as 3× magnification (often written as 3 or 3X).

The listings describe the sheets as clear in appearance.

Options include single-sheet packages and multi-packs, such as five- and six-count packs.

They are commonly described as useful for reading maps, newspapers, timetables, books, and other small text.

Descriptions often call the material durable or 'not fragile' and note that some sheets are a little soft or slightly flexible rather than rigid.
