Night Myopia and Dark Focus of Accommodation

NCT03358550 · Status: COMPLETED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 39

No results posted yet for this study

Summary

Shifts in accommodation at decreasing luminance levels are considered as principle cause for night myopia. Previous studies with laser optometers quantified the dark focus of accommodation up to 3 D. In addition to the measurement of dark focus, the aim of this study was to investigate the influence of an imaginary target at finite distances on the state of accommodation at scotopic luminance.
