[Ophthalmophysiological features of applying soft contact lenses to correct myopia in pilots]

The development of effective methods for preventing and correcting myopia in pilots is one of the most important problems of aeronautic ophthalmology. The majority of Russian and foreign aeronautic ophthalmologists agree that contact correction is the principal method for repair of occupational vision of myopic pilots. Experiments with soft contact lenses with 38 and 70% humor content were carried out. The methodology was based on comprehensive examinations of the vision status and status of the organ of vision under common conditions on the Earth and during simulation of unfavorable flight factors. The results indicate that contact lenses are a safe means for correcting myopia in pilots. This is confirmed by the absence of unfavorable changes in the main visual functions and in the status of the anterior segment of the eye, by a constant level of visual working capacity, and by the absence of negative subjective sensations.
