Summary
| Description | This picture shows the acuity of foveal vision in reading (during one eye stop). The lower line of text simulates the acuity of vision with the relative acuity percentages. To do a test close one eye, fixate the upper line at the fixation point and try to read the words to the right and left without moving your eyes. The result should be similar to the incrementally blurred lower line of text - except that you never have the impression of a blurred text. The reason: Your visual perception is already the result of a massive computational analysis made by your brain. Your system "knows" that the upper line is not blurred, so you don't see it as blurred. But the difficulty of recognition increases with the distance from the fixation point. |
