III. Features
1. Blue Cut Lenses
♦. Definition of blue light: It’s part of the visible light spectrum, which comes from both the sun and artificial light sources like digital screens and fluorescent lights. This type of light gets absorbed deep in the eye, making it potentially impacting to long-term vision. Overexposure to blue-violet light or Harmful Blue Light, especially outside in the sun and through constant use of electronic devices and screens, is why protecting your vision has never been more important.
 |
Nowadays, we spend more time using a wide variety of digital devices to work, learn and be entertained.
Recent digital screens are often equipped with powerful light source such as LED. These digital screens emit intense blue light and can cause eye strain after long exposure.
♦. Blue Cut Lenses: Blue Cut Lenses have a special coating which reflects blue light and prevents it from passing through, allowing wearers to enjoy the added benefit of clearer and sharper vision, without altering or distorting color perception.
2. Progressive Lenses
| Progressive lenses can give you sharp vision at any distance. Instead of being constrained by viewing zones (near and distant, like with bifocals).
The lens location of the correct addition power for the viewing distance usually only requires small adjustments to head position, because near vision tasks such as reading are usually low in the visual field and distant objects higher in the visual field.
Progressive addition lenses avoid the discontinuities (image-jumps) in the visual field created by the majority of bifocal and trifocal lenses and are more cosmetically attractive. |

|
Photochromic Film Lenses are clear indoors and automatically. They adjust their level of darkness to the amount of light outdoors are called adaptive lenses. These lenses are great for people who are always on the move, going from indoors to outdoors several times a day. These lenses adjust from clear to dark, and every shade in between—and that makes it easier than ever to adapt to changing light.
