Accommodative response and eyeglasses prescription are changed by the frequent use of digital devices

Abstract

We analyzed the prescription rate, based on the type of eyeglasses, and the ratio of the type of accommodative function and divided the data into five 3-year periods from 2008 to 2021. With regard to accommodative function, accommodative spasms occurred only in young men and women in the early periods, but this phenomenon has recently spread through all age groups. In addition, accommodative dysfunctions that we could not classify by a past accommodative diagnosis increased in accordance with the spread of smartphone. The prescription rate of progressive addition lens glasses 30 years or older surpassed 80%, based on recent prescription judgments, and the prescription ratio of prism glasses was nearly 70% in teenagers and adult. Consideration of accommodation and convergence is becoming increasingly important when prescribing eyeglasses for digital device users.
