Introduction of Progressive Multifocal Lens:
Progressive multifocal lens is different from bifocals lens. There isn’t 2 or 3 focus on the lens for near, medium or far vision, but countless gradient focuses. since the added value increases continuously in the gradient region, the wearer don't need to confirm the strength for medium and far vision, but to obtain a clear vision from the far point to the near point at the appropriate head position.
1. Progressive multifocal technology, creates 3 zones for different types of vision, no need to take off without fatigue for long time wearing.
2. High-definition coated rasin lenses,1.56 refractive index for clear vison.
3. Supreme nickel alloy material with ductility and ferromagnetic, highly polished and good corrosion resistance.
How to wear:
1. In the early wear, follow the principle: From static to move, from indoor to outdoor.
2. First, choose the appropriate scope for far vision, look straight ahead, but not either side.
3. Determine the scope of the middle vision, slowly down to see through the middle of the transition zone. (There must be a slow adaptation process).
4. Determine the scope of the near, jaw micro-income, eyes down to read the newspaper.
5. Walk in the room, generally 4-5 days will adapt.
6. Please wipe off the marking line with alchohol after adapting to the glasses.
