Frequently Asked Questions
Can I fit any type of lens in these frames?
Yes, all our prescription frames are compatible with single vision, bifocal and progressive lenses. You just need your updated optical prescription.
Which frame material is best?
It depends on your lifestyle. Acetate offers more color variety and is hypoallergenic. Metal is lighter and more discreet. Titanium combines strength and lightness, ideal for intensive daily use.
How do I read glasses measurements?
The three numbers (e.g. 52-18-145) indicate: lens width in mm, bridge width and temple length. Compare with glasses that already fit you well.
