Eccentricity effect. The eccentricity effect is a visual phenomenon that affects visual search. As retinal eccentricity increases (i.e. the light of the image enters the eye at a larger angle and approaches peripheral vision), the observer is slower and less accurate to detect an item they are searching for.

The lifetime risk in normal eyes is about 1 in 300. [8] Retinal detachment is more common in those with severe myopia (above 5–6 diopters), as their eyes are longer, their retina is thinner, and they more frequently have lattice degeneration. The lifetime risk increases to 1 in 20. [9] Myopia is associated with 67% of retinal detachment cases.
A distant object is defined as an object located beyond 6 meters (20 feet) from the eye. When an object is located close to the eye, the rays of light from this object no longer approach the eye parallel to each other. Consequently, the eye must increase its refractive power to bring those rays of light together on the retina.

"The potential dangers of using at-home LED masks include headaches, eye strain, sleep disturbances, insomnia and mild visual side effects," she explained.
– Dardano Sacchetti on the arbitrary nature of the film's setting The base concept for The Beyond was devised by Fulci, Giorgio Mariuzzo, and Dardano Sacchetti, with Sacchetti creating the film's original story. A poster designed by Enzo Sciotti was produced based solely on the treatment in hopes of selling the film to international markets, and the film's title was chosen based on a ...
