An eyesight tester for possibly finding short-sightedness, long-sightedness etc. In the apparatus are included a num-ber of lenses (34, 34a), differing with respect to lens power, embedded in at least one rotationally arranged wheel (24, 26) and located and distributed along an imaginary circle passing through an ocular (36, 38). The power value (for example -3) of each lens (for example 34a) is indicated on the side surface of the respective wheel (24) in such positions relative to the associated lens (34, 34a) that the power value (-3) of each single lens (for example 34a) will appear in a visible position (40, 41) when the associated lens (34a) is in the ocular (36, 38).
La présente invention concerne un dispositif d'évaluation de fonctions visuelles destiné à la détection de myopie, de presbytie, etc. Dans le dispositif est inclus un certain nombre de lentilles (34, 34a) de puissances différentes. Ces lentilles sont réparties dans au moins une roue douée de rotation (24, 26), placées sur un cercle imaginaire passant à travers un oculaire (36, 38). La valeur indiquant la puissance (par exemple, -3) de chaque lentille (par exemple, 34a) est indiquée sur la surface de la roue respective (24) dans une position relative à la lentille associée (34, 34a) de façon que la valeur de puissance (-3) de chaque lentille (par exemple, 34a) soit dans une position visible (40, 41) lorsque la lentille associée (34a) se trouve dans l'oculaire (36, 38).
