Thinner & Lighter Lenses

There are many different types of thin and light lenses (High Index). High index lenses are thinner and lighter than traditional glass or plastic and are geared towards those with moderate to high prescriptions, which can make wearing glasses more comfortable and enjoyable to wear, as they are cosmetically more appealing, this can restore confidence.

High index materials can loose approximately 15-20% of light off the surfaces of the lens, therefore the majority of thinner lenses at Onlookers come with an anti-reflection coating which allows nearly 100% of light through the lens, resulting in sharper vision. Some high index lenses can be manufactured up to 50% thinner and 40% lighter than standard plastic lenses, so gone are the days of thick heavy lenses. Plastic lenses are also a lot safer than heavy, brittle glass lenses.

Other benefits are:

  • Thinner - Improved cosmetic appearance.
  • Lighter - More comfortable.
  • Stronger lenses - Less likely to chip, important for half rim frames.
  • Stronger lenses - Less likely to break, important for rimless frames.
  • Compliments lightweight frames.
  • 100% UV protection.
