The use of smartphones has rapidly increased in today’s society.

Nowadays, a smartphone is one of the main items in our daily lives, that changes our lifestyle dramatically. In 2016, 71.8% of people used smartphones as a result of its rapid increase in worldwide use.

The distance between the eyes and the display of smartphones is too close.

Stress on the eyes is much more significant when using a smartphone for long periods of time compared to other reading distances, such as when reading books, as the reading distance when using smartphones tends to be even shorter than when reading books.

Seeing near for long periods of time causes strain on the eyes.

When we see near, the ciliary muscle works to bring the eyes into focus by adjusting the thickness of the lens.

Eye strain occurs due to the continuous strain on the ciliary muscle when seeing close by for too long.

The REST series assists accommodation of the eye, by adding an assisting power to soften the strain on the ciliary muscle.

Improved natural, comfortable vision by the design that makes eye movement so much smoother. Aspheric surface for base power. The REST series is designed with the ideal aspheric for the back surface of the lens- according to the prescription of the user.

REST is designed with the ideal aspheric surface on the back side of the lens according to the prescription of the user as well as its curve, thickness and size.

Optimized Power on Each Prescription

Stabilizes the optical performance no matter what power the customer has.

Optimized Atoric on Each Prescription

The ideal optical performance has been achieved by the individual aspheric design considering its frame shape.

Optimized aspheric amount on frame shapes

Clear and wide vision field has been accomplished by compensating the aberration to every direction.

Retinal Focus Design

The transmitted lights are evaluated to make the best power. It contributes to make the vision more comfortable, by improving the image quality on the retina as well as making the lens lighter.

A more comfortable vision field has been achieved by creating aspheric design differently on right and left lenses as well as considering eye movement of each eye.

The bottom half of the lens has assisting powers to support near vision.

Therefore, it may cause difficulties when focusing at a far distance when using the bottom half of the lens. Caution is needed when driving in the rain and when using the stairs. 

For user not using their near vision much, it may be hard to notice the effect.
