The LFR-260 is a portable manual refractor providing capabilities to the eyecare provider to perform distance vision testing and subjectively measure sphere, cylinder and axis refractive errors in patients aged from 12-65 years old with healthy visual systems. The device measures spherical error in the range of -10 to +15D and measures cylinder error within +/- 2.5D.

The LFR-260 is a portable digital refractor which allows for determination of refractive error as well as for fully remote refractions. The LFR-260 achieves the similar functionality as Comprehensive Phoropter, MDR-680, which is a standard refractor, but relies on the use of a micro lens array, a highdensity embedded display, and a tunable lens. The reduced number of lenses allows for higher portability and a smaller footprint.
