Rimless glasses typically require stronger lenses because the lenses themselves must support the structure of the frame. However, with modern lens technology, rimless glasses can be fitted with high-index lenses that are thinner and lighter, even for stronger prescriptions. These high-index lenses offer a sleek, low-profile look, making them ideal for rimless or semi-rimless designs. While acetate reading glasses usually feature full frames, they are perfect for those who prefer a lightweight yet durable option that doesn’t require thicker lenses, even with standard prescriptions.
