Abstract
Myopia is one of the most common pathology of refraction in the world, which is one of the risk factors for the development of glaucoma and affects the quality of life.
The research objective: to study the effect of low-intensity fractal light stimulation on visual acuity and color perception in group of students with varying degrees of myopia.
Methods: The Golovin–Sivtsev table, Farnsworth-Munsell 100 HUE TEST, fractal light stimulation device
Results: during the analysis of the initial state of the subjects obtained using the Farnsworth-Munsell test before fractal light stimulation therapy, it was found that the total error score (TES) in the group with medium myopia (group 2) was higher than in students with mild myopia (group 1) (OD by 35.6±7.21 TES, OS by 31.45±2.15 TES). After the therapy in clinical group 2 there was a decrease in the number of errors by an average of 25%. Students with low myopia have an improvement in color perception according to the Mansell test by an average of 8%. The number of errors (TES) in the group with medium myopia (group 2) is higher than in students with mild myopia (group 1) (OD by 19.3±10.64 TES, OS by 4.83±3.58 TES)
Conclusion: it is noted the effectiveness of using the device of low-intensity fractal light stimulation with methodical use during 10 sessions of daily therapy lasting 15 minutes (for both eyes). Subjectively patients observed an improvement in the quality of vision throughout the day, as well as the absence of eye fatigue. Some subjects noted appreciable improvement in visual acuity, despite the identical values of this indicator before and after therapy.

Introduction: myopia is one of the most common pathology of refraction in the world, which is one of the risk factors for the development of glaucoma and affects the quality of life.
The number of people with myopia is expected to increase worldwide by 2050 to 5 billion people. Violations of the light perception system of the eye accompanies any type of ametropia, because they show the function of the retina and optic nerve.
The research objective: to study the effect of low-intensity fractal light stimulation on visual acuity and color perception in groups of students with varying degrees of myopia.
Methods: the Golovin–Sivtsev table, Farnsworth-Munsell 100 HUE TEST, fractal light stimulation device
Results: during the analysis of the initial state of the subjects obtained using the Farnsworth-Munsell test before fractal light stimulation therapy, it was found that the total error score (TES) in the group with medium myopia (group 2) was higher than in students with mild myopia (group 1) (OD by 35.6±7.21 TES, OS by 31.45±2.15 TES). After the therapy in clinical group 2 there was a decrease in the number of errors by an average of 25%. Students with low myopia have an improvement in color perception according to the Mansell test by an average of 8%. The number of errors (TES) in the group with medium myopia (group 2) is higher than in students with mild myopia (group 1) (OD by 19.3±10.64 TES, OS by 4.83±3.58 TES). Students with moderate myopia showed colour weakness for blue and cyan. However, low myopia group showed a yellow-green colour weakness.
Discussion: after the therapy, four subjects have an increase in visual acuity and changes in the type of colour deficiency. Low myopic are characterized by colour weakness mainly on the yellow and yellow-green spectrum with the manifestation of blue. Students with moderate myopia were characterized by colour weakness on the blue, blue-green, cyanide and on the yellow-green spectrum.
Conclusion: it is noted the effectiveness of using the device of low-intensity fractal light stimulation with methodical use during 10 sessions of daily therapy lasting 15 minutes (for both eyes). Subjectively patients observed an improvement in the quality of vision throughout the day, as well as the absence of eye fatigue. Some subjects noted appreciable improvement in visual acuity, despite the identical values of this indicator before and after therapy.
