    Blindness is visual acuity of less than 0.05 in the best eye, with the best optical correction. In the case of low vision, the person may have visual acuity between 0.3 and 0.05 in the best eye, with the best optical correction, with the possibility of using residual vision in daily activities. Objective: People with visual impairment should have access to information on etiology and legislative and optical resources that contribute to improving their quality of life. Method: In addition to the literature search, the method used was the interview of collaborators of the Department of Low Vision of Ophthalmology of the Federal University of São Paulo, and also of collaborators of the Dorina Nowill Foundation for the Blind. The information collected was used to make a booklet. Conclusion: The result was the understanding of the importance of adapting the optical and non-optical text magnification aids taking advantage of patients' functional and residual vision, as well as their needs and rhythms of life. The indication and adaptation of resources is not only linked to the pathology, but also to the lifestyle of the person with low vision, and especially when they use reading, such as study, work or leisure time. And from this study resulted a primer with optical resources and their functionalities. To whom and how resources are indicated and adapted to people with low vision, according to their needs.

    (Universidade Federal de São Paulo (UNIFESP), 2019-05-30) Silva, Paula Baptista Eliseo Da [UNIFESP]; Ferraz, Nivea Nunes [UNIFESP]; http://lattes.cnpq.br/0768359963029007; http://lattes.cnpq.br/6907025986447775; Universidade Federal de São Paulo (UNIFESP)
    Objective: The difficulty in reading is one of the main complaints of individuals with low vision referred for visual rehabilitation, since reading is fundamental for full participation in modern society, permeating productive, intellectual and cultural activities, among others. The improvement in reading performance can be achieved with the use of magnification aids and/or optimization of text readability. The use of digital technologies in reading rehabilitation offers advantages in terms of cost, portability, accessibility and social acceptance. The purpose of this study was to investigate the usability of free smartphone apps with magnification tools as reading aid in low vision patients. Methods: Subjects aged 18 years or older referred to reading rehabilitation with best-corrected visual acuity from 0.6 to 1.3 logMAR in the better-vision eye and usage habit of touchscreen smartphone ≥12 months were included. Among the apps available for the Android operating system, the three with the highest popularity rating, latest update, and interface best suited to the needs of those with low vision were selected. Their usability was accessed using self-reported efficiency scores (from 0 to 10) by patients for accessibility, ease of use for focus adjustment and for text tracking. Binocular near visual acuity and reading performance accessed by acuity and reading speed were measured with the best optical correction and selected apps. The three apps selected (A1, A2, and A3) were compared for utility and efficiency. Statistical models included paired t-test, Wilcoxon and intraclass correlation coefficient (ICC). Statistical significance was considered as p≤0.05 with two-tailed rejection region. Results: 17 participants were included with ages ranging from 26 to 73 years (mean=45.2±13.1 years, median=46.0 years). The apps showed positive and comparable results of utility and efficiency. The three apps presented good results of utility (≥7.0), with A3 presenting the best average score (8.9±1.0, median=9.3). Comparing binocular near visual acuity values with and without the apps, there was a statistically significant difference, with increased visual efficiency for A1 (t=17.5670 and p<0.01), A2 (t=18.0689 and p<0.01) and A3 (t = 18,2006 and p<0.01). There was also a significant improvement in reading acuity with the use of the apps (A1, t=13.5700 and p<0.01; A2, t=21.4199 and p <0.01; A3, t = 20.6606 and p<0,01), but with no statistical difference for reading speed (A1, z=0.639 and p=0.5228; A2, z=0.876 and p=0.3812; A3, z=0.450 and p=0.6529). Conclusion: Tested apps achieved good utility ratios and proved to be efficient, confirming the usability of free smartphone applications with magnification tools and optimization of readability of printed texts as digital resources for visual reading rehabilitation in patients with low vision.
