The Circle Eyeglasses Are Thinner Than Square Ones
The circle glasses men's ones are thinner than square ones. Circular ones do not have corners like square ones, and grinding them will indeed make them appear thinner, but the impact is not significant.
If there is astigmatism, the closer the axial position is to 180, the thinner it becomes. For people with high astigmatism, the axial position of 180 has little effect on thickness. However, people in the 90-axis position have a significant impact on thickness.
The size of the discount prescription glasses lens. If the frame size and pupillary distance are the same, but the slice shape is small. Take a smaller part of the lens, which will also be thinner when ground.
The center thickness of the lens is specified to be no less than 1.0 millimeters for safety reasons. If one is 1.1 and the other is 1.2, then the actual thickness of different lenses will vary.
I am highly nearsighted, how can I choose a pair of thinner glasses? If your pupillary distance is 66, choosing a size of 66 for the frame is the most ideal and thinnest, which means choosing a smaller frame.
If the distance between the pupils is very small and only 58, most people will pinch their faces if they choose the 58 frames. We can only choose to keep the frame as small as possible without pinching our faces. People with high myopia, small pupil distance, and large faces are more limited from the perspective of glasses fitting.
When selecting 1.74 resin lenses, the higher the refractive index, the thinner the lens, while keeping other discount prescription glasses data constant. Of course, 1.9 glass is the thinnest, but its disadvantages are heavy, easy to break, and unsafe, so it is less suitable for people.
Processing with more inverted edges and thinner edges can also achieve better results.
