ChemTech is a collection blue light-blocking readymade readers designed to protect eyes from the potentially harmful blue light emitted by computers, tablets, smartphones, and other screens. 

According to the Vision Council, 65% of Americans report experiencing symptoms of digital eye strain. With ChemTech computer glasses, we can alleviate some of those symptoms with a stylish solution.

Available in 5 styles and multiple colors, ChemTech computer readers are made in plano and single vision intermediate distance powers from +0.25 to +3.00, in quarter increments. That means ChemTech is an accessible solution for contact wearers and presbyopes alike. 

All ChemTech lenses have been tested by a third-party laboratory. ChemTech lenses block approximately 35% of the light in the violet/blue specturym (380nm to 500nm) and more than 50% of the light from 380nm to 450nm.


For opticians and optical providers, ChemTech are a reliable customer favorite. To encourage rapid turnover, ChemTech is available in an attractive 20-piece point-of-sale display. To learn more about our displays or place an order, please contact us here.

What is Blue Light?

Blue light is a general term for the violet-blue portion of the electromagnetic spectrum. Light with a wave length between 380nm and 500nm is considered violet-blue light. This portion of the spectrum is also referred to as High Energy Visible (“HEV”) light. ChemTech glasses and lenses filter a portion of this HEV light with an emphasis on the lower end of the violet-blue spectrum. Blue Light can be found in nature, but is also emitted from man-made devices such as televisions, computers, tablets, smart phones, and fluorescent lighting.

What is Digital Eye Strain?

With the time we spend in front of screen steadily increasing, there has also been an increase in blue light exposure. In turn, many individuals are suffering physical discomfort and distortion, typically after two or more hours of screen use. This is known as Digital Eye Strain (DES). According to the Vision Counil, 65% of Americans report experiencing digital eye strain, while over 87% of Americans report using digital devices for more than two hours a day. ChemTech lenses help alleviate strain on your eyes, which in turn may reduce digital eye strain symptoms.

How ChemTech Can Help

ChemTech glasses and lenses contain a special coating that deflects a portion of the blue light, which reduces eyestrain and improves focus. The other portions of the color spectrum are not filtered, maintaining a sharp image. When these lenses are working, you can see a slight violet-blue hue on the front of the lens.
