Do Self adjusting glasses really work?
It sort of works, but is no substitute for a real pair of glasses. The lenses are made of a pair of cheap plastic, one of which is movable. You could use them in an emergency, but you would be better provided by going for an eye exam and a real pair of glasses. Overall I would not recommend this item.
Can you self adjust glasses?
If you wear metal frames: Simply widen the plastic nose pads using your thumbs until the frames fit comfortably. If you wear plastic frames: Once you’ve soaked the arms of your glasses in warm water for 30-60 seconds, gently apply an upward and outward pressure on the end of the arms to get a more relaxed fit.

A lens in the front part of the frame adjusts to correct myopia, or nearsightedness. A lens in the back has two surfaces, a rigid and flexible one, separated by a clear fluid. To correct close up vision, you move a slider along the frame’s bridge to push around the fluid and alter the shape of the lens.

What are flex lenses?
They are a combination of rigid and flexible lenses that can change prescription to enable sharp focus at different distances (from infinity up to 13″). The appropriate addition range depends on the user’s level of refractive error.
What are variable glasses?
Varifocal glasses, also known as varifocals, varifocal lens, PAL,s or progressive lenses, have a gradual change in strength from the top of the lens to the bottom with multiple focal points in between. This allows you to see all distances and focus points through just one lens.
