TechShield Blue

Frequently Asked Questions

​Following are answers to frequently asked questions about TechShield Blue:

• What is TechShield Blue?

  TechShield Blue is a next-generation, premium anti-reflective blue light lens coating that reduces exposure to blue light from digital screens, energy-efficient lighting, and the sun. It is included as a specialty, D category, AR coating in the full portfolio of new and improved TechShield AR Coatings.

  • Helps reduce excessive blue light
  • Improved scratch resistance⁵
  • Improved smudge resistance⁶
  • Improved cleanability⁷
  • Exceptional visual performance and cosmetic appearance
  • UV protection (UV_R included)

• How does TechShield Blue defend against blue light?

  These blue light lenses both absorb and reflect blue light.

• How much blue light does TechShield Blue reduce?

  TechShield Blue provides the biggest benefit in the 400nm - 430 nm blue light wavelength range.
  
  As a standard practice we do not promote a single fixed blue-light reduction percentage, because we do not feel this is the most scientifically appropriate or accurate way to describe what the product actually does in terms of blue light reduction. Instead, we publish TechShield Blue’s spectral transmittance graph which shows the percent reduction at all wavelengths across the entire blue light spectrum (400nm - 500nm).
  
  Please reference the spectral transmittance graph here.

• Does TechShield Blue protect against UV exposure?

  TechShield Blue automatically comes with UV_R (backside UV protection) included.

• What does TechShield Blue look like?

  TechShield Blue has a near-clear appearance. However, in conditions where a high amount of blue light is present, the product will have an indigo hue. The degree of color is determined by the amount of ambient blue light in the vicinity of the wearer. When there is more blue light present, the product will have more indigo coloration. When there is less blue light present, the product will appear clearer.
   
  TechShield Blue’s near-clear appearance differentiates it from other blue light lens products in the market that only absorb blue light (causing yellow/orange hue) or only reflect blue light (causing purple hue).

• What materials and lens designs are available with TechShield Blue?

  TechShield Blue is available on all lens designs and materials, unless otherwise specified by the manufacturer.

• Is TechShield Blue available on tinted or polarized lenses?

  We are not manufacturing tinted or polarized lenses with TechShield Blue due to the change this would cause in spectral properties of the product.

  Yes, it should be paired with TechShield Elite.
