Stenopeic pinhole glasses (rasterbillen) by German company Eggenfelden, make BioTec D-84307. Dark blue, new. Original price around $33.

From Eggenfelden manual:
Instead of conventional correctional glass, pinhole glasses have a dark perforated sheet of plastic. This perforation bundles the incoming light beam before it enters the eye; this bundled light beam hits the centre of the retina, where vision is at its sharpest.
The nearly sharp image on the retina stimulates the brain to use the eye muscles to fully focus the image. Similar to the pinhole aperture at your ophthalmologist. Our experience shows that regular visual exercising with pinhole glasses has a positive effect on our customers, such as in the areas of perception, color perception and mobility, as well as with light tolerance. In other words, on the entire eye complex. Regardless of the type
and degree of the sight defect. The pinhole glasses have a variety of application options, depending on your personal needs. People with “normal sight” use the pinhole
glasses preventatively, e.g. in the case of chronic stress to the eyes by working on monitors, for activities that require a high amount of visual concentration or for general relaxation, such as to loosen and exercise the eyes.
