Varilux XR series is the first eye-responsive progressive lens powered by behavioural artificial intelligence.
Beyond prescription and eye physiology the design now considers visual behaviour, a prerequisite for fast and precise eye movements.
SEIKO SYNERGY Xtra get the right progressive lens comfort for short sighted and long sighted progressive wearers.
Especially those patients with lots of visual tasks, Synergy Xtra benefits from a giving a higher reassurance of vision.
Microscopic gaps in the coating are filled with Hydrophobic (water repellent) molecules.
Therefore, smoothing the surface of the lens, which allows water droplets to roll from the lens surface without leaving a trace.
An anti-static layer prevents positive dust particles sitting on the lens.
Lenses are protected by a scratch resistant booster, a nano millimetre layer located behind the AR layer.
The scratch resistant booster layer is designed to gradually increases in hardness
Smudges appear on lenses due to uneven nano molecules found on the surface of coatings.
By smoothing fluorinated molecules into a consistent pattern Crizal Sapphire UV coatings offer a superior smudge repellent
