摘要:
Disclosed is a spectacle glass provided with an area for looking into relatively far distances, especially endless distances (long distance part), and an area for looking into relatively short distances and especially distances designed for reading (short distance part), in addition to an area of progression located between the long distance part and the short distance part, wherein the effect of the spectacle glass increases from a value in the long distance reference point located in the long distance part to the value of a short distance reference point located in the short distance part along a curve which is oriented towards the nose (main line) . The invention is characterized in that astigmatic aberration, i.e. the difference between prescribed astigmatism and real astigmatism along circles with a center located 4mm below the centering point and with a diameter of 10 40 mm fulfils the following conditions: two local minima appear in the right spectacle at 95° + 10°(according to Tabo) and at 280° + 10° and in the left spectacle at 85°+ 10° and 260° + 10°; two local maxima appear in both the right spectacle and the left spectacle at 215° + 10° and 335°+10°.
