Scientists created telescopic contact lenses

The video tutorial explains how a special lens can be worn comfortably, allowing normal vision through its center. The lens edge acts as a telescope, magnifying light with aluminum mirrors. To switch between normal and magnified vision, special glasses are used. These glasses employ liquid crystals to change light polarization, selectively blocking parts of the lens.
