The impact of visual environment on the evolution of myopia

Abstract

Our study represents the impact of the visual environment on the evolution of myopia. We established a statistical study of different types of myopia in Morocco. We classed with degrees of myopia. The long-term work of near vision increases a vision-postural stress leads to an increase in accommodative visual stress and convergence, and the correction with traditional lenses leads to hyperopic defocusing peripheral, which stimulates the elongation of the optical axis [1, 4]. We found that the number of myopia is changing during the four years of study and that the correction by traditional lenses does not allow us to slow down the evolution of myopia., this type of management and the visual environment leads us to an increase in the degrees and number of myopia during the four years. The increase in the power of myopia can lead to a pathological state that is preoccupant. We find that the visual environment has an impact on the increase of different types of myopia, especially average myopia in young people. So we have to try new alternatives for myopia compensation as special lenses for myopia braking and orthokeratology lens contact as well as behavioral and environmental measures to decrease visuals.
