Feature

Asymptotic multifocal glasses are the upper optical area of the lens used to look far and the lower optical area used to look near. The degree of the middle gradually change, which used to look at the intermediate area.
We change the curvature of the lens surface from top to bottom, adding positive diopter, which result in the effect of visual correction. Because the degree is gradual, the substitution of the regulation is also based on the shortening of the distance, there is no fluctuation in regulation. As a result, the glasses won't cause visual fatigue. People who wear progressive multifocal glasses will have clear vision at all distances in the visual range.
Most people wear progressive multifocal glasses need about a week of adaptation, but the adaptation period varies from person to person, walk slower when feel dizzy.
As the two sides of the lens is astigmatism disorder district, you need to turn around the neck and eyes in order to see objects on your both sides clearly. When go down stairs, please lower your glasses and use the top area. You'll feel safe and comfortable.

Note:
Using SHINU Multi Focus reading glasses is easy! Select your normal magnification strength (eg. +1.00 or +2.00), which will be visible through the lowest portion of the lens. As you move your eyes up while looking through the lens, the level of strength will decrease. The result: optimal viewing for computer work and looking across the room.

To avoid damage, never clean your reading glasses with paper towels or clothing or alcohol, and also avoid using household detergents or soaps. While a few mild soaps don't harm lenses, today's extra strength soaps are powerful enough to slowly disintegrate lens coatings.
