This article presents a systematic review of the research evidence on the effects of the characteristics of typefaces on the legibility of text for adult readers with low vision. The review revealed that research has not produced consistent findings and thus that there is a need to develop standards and guidelines that are informed by evidence. 
Guidelines for designing text in printed media for people with low vision
According to the collected results it is shown that the relation between letter colour and background colour, or better yet contrast has the strongest influence on legibility for people with low vision.
Accessible statistical charts guidelines for people with low vision
This work includes a set of guidelines for the creation of accessible statistical charts for people with low vision, based on a review of the literature and a previous work developing of a sets of heuristics.
Access to print literacy for children and young people with visual impairment: findings from a review of literature
This article presents a selection of findings from a literature review of best practice models and outcomes in the education of visually impaired children. The review suggested that a key focus of
Age-related differences in the legibility of degraded text
Differences in performance between older and younger participants are used to suggest how older participants’ performance could be approximated to facilitate maximally usable designs.
Reading Digital with Low Vision.
Digital documents on computers and mobile devices permit customization of print size, spacing, font style, contrast polarity and page layout to optimize reading displays for people with low vision.
Adjusting Typographic Metrics to Improve Reading for People with Low Vision and Other Print Disabilities
A new software technique called typometrics is presented, which enables users to choose a wide range of typographic metrics to assist reading and a three part study is planned to collect baseline data for implementing typometric interventions to improve reading.
Effects of Line Spacing on Reading Performance of Normally Sighted and Simulated Visually-Impaired Subjects: A Pilot Study Using Arabic Words
The study aims to evaluate the role of line spacing during reading in normal and visually-impaired persons. A total of 225 normally-sighted participants with mean age of 23.7 years were asked to read
The impact of font type on reading
Significant differences in brain activation patterns exist between readers with and without dyslexia (Shaywitz, 1998). One possible area of difference involves font style that has led to the
Assessing of Glance Legibility of Hangul Typefaces by the Elderly
The aim of this study is to investigate the glance legibility of three types of Hangul typeface by the elderly.
Towards evidence-based typography: Literature review and experiment design
During several centuries of typography many rules have been developed purporting to ensure better legibility and readability of printed copy. However, modern experimental research questions the


Legibility of outline and solid fonts with wide and narrow spacing
Using a visual acuity criterion for legibility, outline fonts are about 82% less legible than their solid counterparts. Crowding effects are similar for the two types of fonts. Both sets of results
Adjustable typography: an approach to enhancing low vision text accessibility
Millions of people have low vision, a disability condition caused by uncorrectable or partially correctable disorders of the eye. The primary goal of low vision rehabilitation is increasing access to
Enhancement of peripheral letter recognition by typographic features
This study demonstrates an experimental strategy that can improve peripheral letter recognition by modifying typographic design features based on psychophysical data. The approach is based on the
Making text legible: designing for people with partial sight
Basic guidelines for making effective legibility choices that work for nearly everyone are provided.
Developing printed materials for patients with visual deficiencies.
In preparing educational materials for patients with vision deficiencies, nurses must take into consideration type size, typeface, and color. Patients surveyed preferred 14-point, sans serif type.
Effects of Typeface and Font Size on Legibility for Children
Eighty children (kindergarten through 4th grade) performed discrimination and identification tasks for tachistoscopically-presented letter pairs. Letter pairs manipulated font (Times New Roman,
Psychophysics of reading. XV: Font effects in normal and low vision.
There are small, but significant, advantages of Courier over Times in reading acuity, critical print size, and reading speed for subjects with low vision and for print sizes close to the acuity limit, choice of font could make a significant difference in both normal and low-vision reading performance.
