Reading performance and eye-movements through Varilux 2 and ST-25 lenses.
Reading rate, reading comprehension, and photoelectrically recorded eye movements while reading through Varilux 2 and ST-25 lenses were compared for seven subjects who were predominantly myopic, who ranged from 25 to 60 years of age, and who wore adds of 1.00 to 2.25 D. Tests were done at near (40 cm) and intermediate (57 cm) distances before and after a month of adaptation to the lenses using paragraphs that subtended less than 14 deg. A three-way analysis of variance indicated no significant differences in performance between the two types of lenses.
