Resumo

To determine near and intermediate vision areas of progressive addition lenses by means of a deflectometer.Twenty-two progressive addition lenses with +1.00 SD far power and two different additions (add 1.00 and 2.00; eleven subjects in each addition) were studied. Near and intermediate vision areas within 0.50 CD isoastigmatic lines were determined.There are significant differences between near and intermediate vision areas of the studied lenses. There is also an inverse correlation between the addition and intermediate areas as well as direct relation between the vertical length of the corridor and its area.Based on those findings, progressive addition lenses can be selected to suit the wearer's visual requirements.
