Background: Stress in the visual system can have a profound effect on societal development and deprivation, predisposing to ocular, systemic and psychological morbidity. Reading difficulties are becoming more prevalent as the demands of education and information technology increase. It is therefore increasingly important to be able to measure the extent of these difficulties and if possible to attribute them to a cause.

Objective: It is generally accepted that a Serif font will be harder to read than a Non-Serif font. This study seeks to show using a new measure of reading speed that this is because of the Serif Font’s relatively higher spatial frequency and an association with pattern glare, visual stress and binocular deficiency.

92 year 7 children (11-year-olds) were screened using a new measure of the comparative rate of individual character recognition. Two different lines of 60 random letters were used, one in a serif font (Times) and the other in a non-serif font (Gills Sans). The Times font was printed in black and the Gill Sans font in a Teal colour.

Results: The results showed that the non-Serif font (Gill Sans) was read faster than the serif font (Times) N = 92 p = 2.19E-09, due to it is argued a high degree of binocular deficiency in this group.

A more detailed analysis of the data showed that 65 of the subjects were contributing to the significance of this result (p = 6.84E-16). The remaining 27 subjects read the Gill Sans slower or the same (p = 0.00045) due to the lower contrast of the teal Gill Sans letters, which confounded their lower (easier) spatial frequency. This is likely to be seen in subjects with reduced contrast sensitivity and by implication poor visual development rather than a binocular dysfunction.
