Now, telescopic contact lenses that allow users to zoom in and out
A new type of contact lenses has been developed, which, when paired with special spectacles, bestow telescopic vision on the wearer.
The contact-lens-and-spectacles combination magnifies scene details by 2.8 times, the BBC reported.
Polarising filters in the spectacles allow wearers to switch between normal and telescopic vision.
The telescopic sight system has been developed to help people suffering age-related blindness.
The contact lens has a central region that lets light through for normal vision.
