The video discusses pinhole glasses, which use the pinhole effect to improve vision by blocking peripheral light rays, allowing only central rays to reach the eye. This effect can be tried at home using a small hole in paper or fingers. Clinically, pinhole glasses help determine if blurry vision is due to refractive issues. Vuity eye drops also use this effect by shrinking the pupil. However, pinhole glasses do not cure myopia or presbyopia. They are fun to experiment with but should not be used for driving or daily tasks.
