The Effect of Changing Colours on Central Crowding Reading

Background: Crowding can be defined as the impaired recognition of closely spaced objects. Changing colour and lighting enhance visual comfort perceptual troubles that influence vision reading. Objective: The current study was aimed to investigate impact changing flanker distance unflanked targets with colours on central crowding reading for subjects their distant best correction (BCVA) equal or greater than 6/6. Methodology: Six native English speakers (age: 18–38) who participated in a cross-section intervention were asked identify orientation letter E (flanked unflanked) different directions around target (red, green, blue black) white background. Results: Different affect (p<0.05). However, red not affected by flankers (P > 0.05). Conclusion: Central is crowding. changes flankers.
