â¹5,800 sunglasses that can block out TV screens designed
Ivan Cash, a US-based inventor, has designed a pair of sunglasses called IRL (In Real Life) Glasses that can block out TV screens. Priced at around â¹5,800, the glasses block the wavelengths of light that comes from LED and LCD screens. The glasses, currently in beta, are all black, with the IRL logo printed in white on the sides.
