The change of lifestyle
Smart phones have rapidly been spread in today’s society.
Nowadays, smart phone is one of the main items in our daily life that changes our lifestyle. In 2016, 71.8% of people use smart phones as a result of its rapid spread.
The use of smart phones is stressful to the eyes.
The distance between the eyes and the display of smart phones is so near.
The stress to the eyes is much bigger when to use smart phones for a long time compared to other reading distances such as when reading books, because the reading distance of when using smart phones tends to be even shorter than the general reading distance such as when reading books.
Why does eye strain occurs?
Seeing near for a long time causes eye strain.
When we see near, ciliary muscle works to bring the eyes into focus by adjusting the thickness of crystalline lens. The eye strain occurs due to the continuous strain of ciliary muscle after seeing near for a long time.
“REST” series assists you to focus
The REST series assists the accommodation by adding a assisting power to soften the strain of the ciliary muscle.
Harmonic eye assist aspheric design
Improved natural, comfortable vision by the design that makes eye movement 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 realized by the individual aspheric design considering its frame shape.
Optimized aspheric amount on frame shapes
Clear and wide vision field has been realized by compensating the aberration to every direction.
Retinal Focus Design
The transmitted lights are evaluated to make the best power and it contributes to make the vision more comfortable by improving image quality on the retina as well as making the lens lighter.
Eye assist aspheric design
More comfortable vision field has been realized by designing aspheric design differently on right and left lens considering eye movement of each eye.
Available from four types for your style
Assists the accommodation of the eyes「Assist area」
【REST series is a new concept lens for everyday use designed by applying the techniques achieved in designing progressive lenses.】
- The bottom half of the lens has assisting powers to support the near vision.
Therefore it may cause difficulties when focusing at a far distance using the bottom half of the lens.
- Caution is needed when driving, in the rain, and when using the stairs.
- For user not using the near vision much, it may be hard to recognize the effect.
