The Effect of Color and Positional Noise on Reading Performance in Human Vision

BACKGROUND: Reading can be described as a complex cognitive process of decrypting signs to create meaning. Eventually, it is way language achievement, communication, and sharing information ideas. Changing lighting color are known improve visual comfort the perceptual difficulties that affect reading for those with poor vision.
 AIM: This study aims investigate effect changing wavelengths different levels positional noise on performance participants best-corrected distant acuity (BCVA) 6/6 or better.
 METHODOLOGY: Twenty English speakers BCVA better were asked read words presented in printed format. The stimuli black print horizontal arrangement matte white card. They degraded using produced by random vertical displacements letter position below above line three levels.
 RESULTS: Introducing affected word recognition differently wavelengths. role short wavelength enhancing orthographic clear – they reduce effects noise. error rate duration time have wavelengths, even when introduced.
 CONCLUSION: not light. However, mean differences wpm Also, introducing affects
