Featured Product

TOG USA is a proud supplier of Transitions®️ GEN S™️, the new lens standard. A giant leap of technology available now.
Your trusted partner for Transitions® lenses
As a licensed Transitions® Optical Ltd. partner, TOG USA is pleased to supply Transitions® lenses, the preferred choice for prescription glasses in the country.
Transitions® lenses are a type of lens that darkens when exposed to sunlight because of the patented photochromic dyes used during their manufacturing process. When indoors, these same lenses return to their initial, clear color.
Benefits of Transitions® lenses:
- Completely clear indoors
- Exceptional eye protection
- Quicker activation and fadeback
Why are Transitions® lenses favored by millions?
To address the ever-changing outdoor sunlight conditions, Transitions® lenses are customized to create ideal hues for every situation. This is due to their ability to adapt to varying levels of darkness, allowing only optimum levels of light to enter the eyes.
Transitions® lenses provide comfort to your customers, allowing them to easily travel between venues and activities without taking off or changing their glasses. The lens’s ability to control light levels can lessen strain on the eyes and eliminate eye discomfort, ultimately aiding your customers’ adaptability to light contrast.
Our collaboration with Transitions® has made it possible for us to provide high-quality, versatile lenses that accommodate virtually any frame. TOG USA also takes pride in the ability to offer a wide range of Transitions® products.
