Learning Objectives:

Upon completion of this course you should understand:

  1. Learn about Captivate polarized lenses with filters to attenuate color signal overlap in the retina, increasing color vividness and discrimination, sharpness, contrast and detail.
  2. Learn how our brain interprets color from retinal signals.
  3. Learn how color signals are redefined with selective filtering of specific wavelengths of light.

Course Description:

In this course, we will learn about Captivate polarized, color-enhancing, sun lens technology from Wiley X. We all know that polarized lenses enhance contrast and detail by blocking reflected glare, but now we will learn how polarized sun lenses are better with color and contrast-enhancing filters. We will learn how  Captivate color-enhancing filters eliminate overlapping light wavelengths of low chromaticity (hue and colorfulness). Specific wavelengths confuse the color signals received by the brain and contribute to poor contrast and color discrimination. By their elimination, the brain receives precise color signals, and our perception of color and contrast is enhanced.  We will also look at the effect of short wavelengths of blue light on visual haze due to retinal defocus and scatter along with its potentially damaging impact on the retina. On the other side, we will discuss beneficial blue light’s positive effects on our health and circadian rhythm effects.
