A new concept in retinoscopy and refraction, this neat unit combines 40 power combinations. It is a large aperture retinoscopy rack and a mini-phoroptor all in one pocketable instrument. The large 20mm lens diameter allows easier retinoscopy, particularly on children. The comprehensive range of spheres (-10.00 to +10.00 in 0.50D steps) gives the practitioner a unique and versatile instrument.

This unit can be used comfortably at arms length and the lenses are of trial case quality. Supplied in an attractive protective case.
