Magnifiers are typically characterized using a "standard" value of 0.25 m. A magnifying glass operates as the simplest form of optical instrument. It is essentially a hand-held lens that converges light to produce an enlarged, upright image that appears to stand where light doesn't actually converge, known as a 'virtual' image.
MonoMouse is a handheld electronic magnifier manufactured by Bierley, designed to help people with a visual impairment to read printed text or images. [1] [2]Originally developed by Ian Bierley in 2003 for use by his mother, who had glaucoma, and then later released as a commercial product supplied through opticians in 2005. [3]

Fresnel lenses are used as simple hand-held magnifiers. They are also used to correct several visual disorders, including ocular-motility disorders such as strabismus. [73] Fresnel lenses have been used to increase the visual size of CRT displays in pocket televisions, notably the Sinclair TV80. They are also used in traffic lights.

A traditional handheld refractometer is an analog instrument for measuring a liquid's refractive index. It works on the critical angle principle by which lenses and prisms project a shadow line onto a small glass reticle inside the instrument, which is then viewed by the user through a magnifying eyepiece.
