This reading test, which already exists in English, Danish, Turkish and German, enables us to ascertain that we read an average of 80 words per minute and that that we take just over 3 seconds to read a 14 word-sentence.
The tests that are usually used to measure near visual acuity are governed by different criteria that affect the form and content of the sentences used, which makes a final evaluation difficult. The study has been published in the latest issue of the Journal of Cataract and Refractive Surgery and has been carried out by the research group headed by Jorge L. Alió.
The design of this new test is based on the Radner method, and has been standardised in Spanish to reflect the similarity in the number and length of the words, as well as lexical and grammatical levels of difficulty. The reading tables contain 24 phrases and are also similar in number of syllables and words (14).
“This test measures both near visual acuity and reading speed from any distance, i.e., the most comfortable reading distance for the patient”, affirmed Alió. The design of this test is based on an adjustment scale for distance that allows ophthalmologists to translate the visual acuity values obtained into the baseline reading distance of 40 cm.
The study evaluates each patient’s reading capability by measuring his/her reading speed. The researchers point out that “a normal reading speed is 80 words per minute”. The test was tried out on different groups of patients with different cultural levels in order to obtain an understandable trial, regardless of their socio-cultural levels.
An experiment with 60 persons without eye disease
The study evaluated 60 volunteers without any eye disease that could influence the results. The participants were divided into two groups (university education and junior school education). The first group attained an average reading time of 3.51 seconds, and the second group attained 4.12 seconds, the average reading time being 3.81 seconds for all of the sentences.
“As was expected, the reading time was longer for those phrases the readers found most difficult to read. So, the group with a lower level of education made more errors in reading and they read slower than the group with a university education”, underline the authors.
The research can be used in cases of eye disease (cataracts, macular degeneration and amblyopia), by taking into consideration that “a slow reading speed indicates visual function and quality of life deficits”. In this way, this test could be used in future studies to measure the reading speed of patients with multifocal intraocular lens implants (IOLs).

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
