Drilling Techniques
Drilling techniques are crucial when fitting rimless glasses. For the outer upper lens, ensure the hole is drilled from the outer surface of the lens inwards, slightly angled towards the optical center, to ensure the flat surface of the nut makes tight contact with the inner surface of the lens. During initial installation, only minor adjustments to the hole position are needed to achieve a perfect fit between the lens and frame, effectively preventing screws from loosening.
For the inner upper lens, start drilling from the positioning point on the inner surface of the lens, tilting outwards and slightly angled towards the optical center to ensure precision and aesthetics. For the outer upper lens, drill from the outer surface of the lens inwards, slightly angled towards the optical center, to ensure the nut makes full contact with the inner surface of the lens. During initial installation, only minor adjustments to the hole position are needed to achieve a perfect fit between the lens and frame, effectively preventing screws from loosening.
Screws and Installation Balance
Since rimless glasses lack the fixing effect of a frame, screws play a vital role. During installation, choose nose-side screws, whose length should be slightly shorter than the inner surface of the lens. For the inner upper lens, it's not recommended to add washers to the outer surface of the lens, as resin lenses have some elasticity. After installing the four screws and nuts, close the temples and carefully observe the balance, making minor adjustments before tightening the nuts.
Finally, lightly apply 502 glue to the nuts for fixation. After it dries naturally, the rimless glasses installation is complete. Rimless glasses assembled using this method will remain stable and secure even after three years of wear. During installation, pay attention to screw selection and balance adjustment, and use appropriate fixing methods to ensure the stability of the rimless glasses.
