High Index Aspheric Lenses


Aspheric lenses have less distortion so that we can make the lenses even thinner and lighter. High index aspheric lenses are suitable for any degree and vision (hyperopia / myopia / astigmatism).There is no additional fee incurred for such thinner lenses at OWNDAYS.

Transition Lenses

Plus ¥5,000+tax

The colour of the lenses changes accordingly to the amount of UV rays. The lenses get darker when exposed to more UV rays, while getting clearer when exposed to less UV rays.The pair of transition lenses can be used as clear spectacles as well as sunglasses. Please note that the lenses get clearer more slowly compared to when they get darker. Also, you may wish to know that it is not the amount of light but the one of UV rays that changes the colour of the lenses.

Transition Lenses (change the colour of the lenses due to the amount of UV rays) *Refractive Index: 1.56
The lenses get darker when exposed to UV rays.

Polarised Lenses

Plus ¥8,000+tax

The lenses are less affected by light from the surface of the water and diffuse reflected light so that your vision is still clear. Polarised lenses are different from sunglasses, which are just coloured lenses and make your vision darker. For polarised lenses, the film inserted between the lenses reduces the amount of unnecessary light such as UV rays and reflected light and only lets natural light go through.They are very effective in outdoor activities such as fishing, golf, skiing as well as driving.
