Consider possible uncertainties after the lens is installed.

Usually, in-store frames are made of plastic samples rather than actual lenses, so they weigh slightly less. However, it is necessary to consider the approximate weight of the lens in advance according to its own degree when trying it on, in case the weight is not suitable for real wearing. If the pupil distance is too small, it is not suitable to wear a wider frame. The machinist should strictly follow the left and right pupil distance instead of taking the average, otherwise, there will be pupil distance error in the left and right eyes, which will cause discomfort in wearing.



Benefits of Progressive Lenses

Progressive lenses are different from traditional reading glasses and bifocal glasses in that bifocal reading glasses have to constantly change the focal length, causing fatigue. And there is no clear dividing line between the two focal lengths. They are more comfortable, more beautiful. When you see far or see near, a pair of glasses can be done, so they become the best choice for old people little by little.

Progressive lenses allow multiple fields of view to be merged into a single lens with no discernible difference between the fields themselves. Degrees of the lens vary gradually from far to medium to your full reading. This is why progressive lenses are often regarded as no-line bifocals or trifocal points.
