"The cutting-edge instruments will make the screening and refraction processes more comfortable, precise and effective," said Kok Leong Lim, president of the Essilor China lens division.
One of the new launches, called Vision R (TM) 800 is a phoropter - a device that has different lenses used for refraction of the eye during sight testing.
But over time, people will need refraction or examination for their vision, so that we need to have that kind of store to know at which stage the user is.
