How to choose a reliable myopia glasses frame? Firstly, check if the lining has a trademark for appearance. Choose a lining with trademark, model, and other information. Pay attention to the engraved information on both sides of the cheap eyeglasses near my legs.
The lining has a trademark logo, can you buy it with confidence? Not necessarily! Because upon closer inspection, one will notice that this trademark is affixed with adhesive, and upon closer inspection of the mirror legs, there is also no trademark engraving. Essentially, it's not much different from the one above. Look at the lettering on the mirror legs. You can tell at a glance whether this frame is reliable or not. Even carefully reading the information on the eyeglasses frame tag.
The thickness and clarity of lenses are not only determined by the refractive index but also by the choice of cheap eyeglasses near my frame and the distance between the customer's pupils. Why choose a small, round frame for high myopia instead of a small flat one?
Because the lens is round before processing, with a thin center and thick edges, the middle circular area is the thinnest part. Visual clarity is also the best aspect. Why can't we choose a flat and a small one? Because the flat one is rectangular and sits at the edge of the lens where it is thick.
Next, the distance between the pupils also determines the thickness of the lens. If the same two people choose the same lenses and frames, the one with a larger pupil distance will be made thinner.
Wearing glasses is a lifetime, it's worth spending some time to learn more. Especially as more and more people choose to have their glasses matched eyeglass online!
