|Abstract|| Purpose: To determine the association among refractive errors correction with writing and reading speed in Adults.
Methods: A cross-sectional study was conducted in 41 adults (11 men and 30 women) from National Institute for Adult Education. The mean and deviation standard for age was 55.05 ± 9.03 years and range from 42 to 76 years old. A complete refractive examination, including static retinoscopy without cycloplegic agents was performed. We considered as myopic adults whose with spherical equivalent (SE) < -0.25 diopters (D) in at least one eye, hyperopic to those adults with SE > +0.25 D in at least one eye and with astigmatism to those adults with cylinders < -0.75 D in at least one eye. The assessment of speed writing and reading were made with and without optical correction, counting the numbers of words that, the participant reads or writes per minute. All procedure was conducted according to declaration of Helsinki.
Results: The prevalence of myopia was 60.98 % (95% Confidence interval [CI]: 75.91 – 46.05%), the prevalence of hyperopia was 36.59 % (95% CI: 51.33 – 21.85 %) and the prevalence of astigmatism was 21.95 % (95% CI: 34.62 – 9.28 %). The mean and standard deviation of speed of reading without correction was 58.71 ± 17.64 and with correction was 85.15 ± 24.24. The mean and standard deviation for speed of writing without correction was 52.12 ± 14.71 and with correction was 53.24 ± 16.50. Comparing the speed of reading without and with correction, we found significant differences (K-S test Z = 0.612, p = 0.848 and Z = 0.944, p = 0.335; t=-6.08, p < 0.001). Comparing the speed of writing without and with correction, we do not found no significant differences (K-S test Z = 0.925, p = 0.359 and Z = 0.893, p = 0.402; t = -0.94, p = 0.352).
Conclusions: The results suggest that correction of refractive errors, improve the reading speed but the writing speed does not.
