To read the signs in the iris, the eye must be both illuminated and magnified.Torches should be well constructed and use a lens-bulb or LED to provide a small and focused, rather than diffused, light patch. This combination torch and LED is built to this specification, while household, Maglite and ordinary map-reading torches are not. However, this Iridology torch is also perfectly useful for map reading and other magnification purposes.
The Eschenbach Mobilux 7X illuminated magnifier torch uses a replaceable lens-bulb.
Torch: White and grey
