Close to 50% of population in the developed countries are prescription frame users. However, this important segment of more affluent consumers is very often overlooked by most sunglasses marketers.

Existing sun-block products catered for this segment are:

- Rx sunglasses

- Photochromatic lenses

- Clip-Ons

UNI-CLIP Custom Clip-On Sunglasses are the most cost-effective and cosmetic appealing alternate solution for protecting valuable vision of prescription spectacles wearers from harmful UV sunlight. The clips could all be assembled in-house without the Rx frame leaving the store.
