Development and Validation of a Digital Optotype for Near Vision in Greek Language.
NCT04242836 · Status: COMPLETED · Type: OBSERVATIONAL · Enrollment: 100
Last updated 2020-01-27
Summary
Primary objective of our study is to develop and validate a computer-based digital near-vision optotype based on the Greek version of the print MNREAD.
Conditions
- Presbyopia
- Low Vision
- Near Vision
Interventions
- DIAGNOSTIC_TEST
-
MNREAD testing
One randomly selected eye is included for each study participant. Participants respond to the near vision chart with defined environmental circumstances at 40cm viewing distance. All four parameters (RA, MRS, CPS and ACC) are evaluated.
