Benefits of Progressive Lenses

The lens looks like a single vision lens, with no dividing line between degrees. Not only is it beautiful in appearance, but more importantly, it protects the privacy of the wearer's age (for the wearer of reading glasses). There is no need to worry about showing the secret of the wearer's age by wearing the glasses. Because the degree is gradual, the replacement of the adjustment effect is increased step by step according to the shortening of the close distance. There is no adjustment fluctuation, which is not easy to cause visual fatigue. Clear vision can be achieved at all distances in the visual scope.


Why the lens coating is not uniform?

Sometimes we find differences in the color between the convex and concave surfaces, between the center and the edge of the lens, and the anti-reflection effect between the convex and concave surfaces. his is mainly because the lens coating is that it is plated on one surface and then turned over to another surface. And Areas with small curvature changes are easy to coat. So the center of the lens has reached the desired thickness of the film but the edge has not. At the same time, the different curvature of the convex surface and concave surface causes the different coating speed. So the surface of the lens will show green in the center and lavender red or some other color at the edges.
