About This Product
These T Tool pinhole glasses are a bit different from regular prescription specs – instead of lenses that refract light, they use a bunch of tiny holes to focus light directly onto your retina.
The idea is that this can help reduce eye strain and improve vision over time by exercising the eye muscles.
Kind of like a workout for your eyes.
Each pack comes with 4 pairs, all in black with full frames.
They're not a replacement for prescription lenses, but they can be a helpful tool for eye relaxation and training.
