polycarbonate, materials with moderate refractive indices. High-index lenses, however, utilise advanced polymers or glass materials with higher density and refractive capabilities. Additionally, these lenses often feature aspheric designs. Unlike conventional spherical lenses that have a uniform curvature, aspheric lenses are flatter and slimmer, which further reduces distortion and bulk while improving peripheral vision. CHOOSING THE RIGHT HIGH INDEX LENS Selecting the right high-index lens depends on several factors, including: • Prescription Strength: The stronger the prescription, the higher the refractive index required to achieve a noticeable reduction in thickness. • Frame Style: High-index lenses complement various frame styles, but the choice of frame can influence lens thickness. For example, rimless or semi-rimless frames might benefit from slightly lower indices to maintain durability. • Lens Coatings: High- index lenses typically require anti-reflective (AR) coatings to minimise glare, as the denser material reflects more light than standard lenses. • Cost Considerations: High- index lenses are generally more expensive than standard options. However, the investment is often justified by their improved aesthetics, comfort, and versatility. ARE HIGH INDEX GLASSES WORTH THE INVESTMENT? For many eyewear users, the answer is a resounding yes. High-index glasses offer a combination of functionality and fashion that can enhance both vision and self-esteem. Their benefits are particularly pronounced for individuals with strong prescriptions, but even those with moderate prescriptions can appreciate their lightweight and stylish attributes.
