REFRACTIVE INDEX
Design Eyewear / Adelaide CBD, Rundle Mall
The refractive index helps to reduce the volume of the lens material, resulting in a thinner lens. The higher the refractive index, the denser the plastic. Depending on your spectacle script and frame selection, you may want to consider a higher index in order to make your lenses feel more comfortable, more durable and thinner.
If you wear a minus lens (for near-sightedness), your lens will be concave in shape – thinner at the middle and thicker at the edges. The edge thickness can be reduced with a higher refractive index. With a plus lens (for farsightedness) the lens shape is convex – thinner at the edges and thicker at the centre. The central thickness will be reduced as the refractive index increases.
