The days of unsightly, thick “Coke bottle” lenses are well behind us, thanks to new technologies that have made thinner and lightweight lenses the norm.
Spectacle lenses are generally made from a plastic-based material or polycarbonate-based material. Glass is rarely used now due to its heavy weight and concerns about safety.
Plastic-based lenses offer excellent optical clarity, are lightweight and shatter-proof. Our lens supplier, Zeiss, even includes a full UV protection component ('UV Protect'), which filters out just as much UV light as a sunglass, in all of their clear plastic lenses!
Spectacle lenses are available in five different densities, called 'indexes'. The higher the index, the thinner and lighter your lenses.
Polycarbonate-based lenses are 'mid-index', so are lighter and even more impact-resistant than standard plastic lenses. They are often used for children and industrial workers and are the lens material required in safety glasses.
