Background and Objectives: The purpose of the study was to determine changes in accommodative parameters after constant reading from digital print (Kindle and MacBook) and hard print (Novel).

Methods: A total of 30 subjects were enrolled in the study with the age group between 18 to 30 years (21.4 ± 1.5) years. A complete eye examination was performed on all subjects including the assessment of accommodative parameters. Subjects were made to read a novel for 30 minutes after which an assessment of accommodate parameters was done again, A break of 2 hours subjects were made to read from kindle for 30 minutes followed by an assessment of accommodative parameters. Again, a break of 2 hours was given, followed by reading on MacBook and, an assessment of accommodative parameters was done post-reading.

Results: There was a significant decrease in the Negative Relative Accommodation (NRA) and binocular Accommodative Facility (AF) while using the MacBook in comparison with the other devices mentioned. There were no significant changes in the other Accommodation parameters i.e., Near Point of Accommodation (NPA), Positive Relative Accommodation (PRA), Monocular Estimation Method (MEM), and uniocular Accommodative facility.

Conclusion: Reading from MacBook induce slight increase in accommodative parameters, while Kindle can be used for reading with minimal effects on accommodative parameters as compared to traditional books.
