Tried and tested: Jai Kudo Blue Shield

Blue light is currently the hot topic in the ophthalmic lens sector. With exposure to the dangerous spectrum of blue light higher than ever, most major lens producers now offer a filtering option in their product portfolios.

Exposure to this harmful blue light spectrum comes from a number of sources: TVs, computer screens, smart phones and tablets and, in particular, the current generation of energy-saving light bulbs. All these examples are difficult to hide from and you have to wonder if blue light coatings will soon end up in the same often-specified bracket as AR coats. That’s probably a question for another time.
