The refractive index of the material used to make lenses determines their thickness. The index measures how well a lens material bends light. Get thinner lenses by selecting eyeglass lenses made of material that has a high refractive index, suggests AllAboutVision.com.
The aspheric design of a lens features a curvature from the center of the lens towards the edge and offers high optical performance. Choose aspheric lenses that give your eyeglasses an attractive profile without making them thicker, recommends AllAboutVision.com. The lenses provide a better appearance by minimizing unwanted magnification, and some designs make peripheral vision clearer.
Progressive eyeglass frames factor into the thicknesses of you lenses. By choosing a smaller centered frame, you can reduce the overall weight and thickness of the lenses even if the lens material you choose is made of low-index material. Thinner lens materials are likely to get scratches, meaning you should consider lenses that come with anti-scratch coating to ensure their longevity.
