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

Summary
Reading is a complex cognitive process of decoding signs to derive meaning. It is a way of language comprehension, communication, and sharing ideas and information. Reading is underlined by three basic processes: printed word recognition, language comprehension, and sight perception [1]. Recognition of the word is considered an essential literacy skill that facilitates access to and processing of written language, as well as affects reading performance. Word recognition can be defined as the ability to automatically and accurately recognise words with and without semantic setting. It is a performance stamp of skilled readers or.
