Abstract

In a computer-implemented method, a server 3 connected to a network 1 displays text 9 on a background 11 on a screen 7 of a user computer 5 also connected to this network 1. The text 9 and the background 11 are displayed in a color that corresponds to the effect that the use of a physical color filter in front of a person's eyes would have on the person's perception of black letters on a white background. The person's reading ability is then measured with a color chosen by the person and these measurement results are compared with each other and compared with the reading performance with black text on a white background and conclusions are drawn from this. If an improvement in reading performance is observed, glasses are then assembled having lenses provided with the color filter with which the best reading performance was observed.

Description

DETERMINING READING ABILITY AND EFFECT OF COLOR FILTERS ON READING PERFORMANCE DESCRIPTION: Technical field of the invention The invention relates to a method for determining the reading ability of a person in order to be able to determine the effect of color on the reading performance of this person in order to assemble glasses with colored lenses with which the reading performance of this person improves. The invention further relates to a method for determining the effect of color on the reading performance of a person and to software for performing the method. The invention also relates to a method for manufacturing glasses with lenses provided with a color filter determined using the method. Background of the invention WO2004/112598A1 discloses a method that can be used in providing a visual aid, such as the selection of a tint for a screen, to alleviate symptoms of dyslexia and other optical disorders. This known method provides a test procedure in which parameters of eye tracking are associated with color parameters of the visual aid in order to select the optimal color of the visual aid. A device is used to track the movement of the eye during reading. A disadvantage of this known method is that the person for whom the visual aid is intended must come to a location where a device to track the movement of the eye during reading is present. Summary of the invention It is an object of the present invention to improve the method for determining the color filter with which the best reading results are obtained for the person, such that the suitable color filter can be determined for more people in a certain time.
