Visual scientists may have discovered how to reduce the pedestrian collisions of some blind people in crowded open spaces, such as bus stops, shopping centers and city squares. Researchers have determined which direction the blind collision between pedestrians is caused. This understanding will lead to the development of new glasses and expand the vision of people with missing vision.
A recent article published in the Journal of Visuals entitled "The Risk of Peripheral Visual Loss and Pedestrian Collision". The authors established a mathematical model to determine the risk of collision in 42 patients with retinitis pigmentosa.
“We found that patients had the highest risk of collision when walking at a 45° angle,†said study author Eli Peli. “This means that if any field of view expansion device covers this angle, it means it is effective.â€
Peli and his colleagues are developing a new pair of glasses with prisms. The prism corrects vision defects primarily through light refraction. In order to minimize peripheral vision loss, the new prismatic glasses will expand the patient's visual area by refracting the light, allowing the missing vision to function.
Patients with blindness (hemenosis) in the left or right half of the eye caused by stroke, brain tumor or trauma, and retinitis pigmentosa, Usher syndrome, choroid-free and advanced glaucoma, will one day upgrade them by using this product under development. The visual range.
