In the last article, we covered lens materials and coating options, and their effect on lens optical performance. We briefly covered blue light attenuating lenses and coatings with a promise to share more in this June article. To that end, this article will cover the limits and benefits of the two types of blue light lenses in the market (indoor and outdoor). More and more consumers search blue light on the internet as they experience increased concern about the effects of digital screen time on eyes. They come to you for guidance and present you with the opportunity to help them understand the different types of blue attenuating lenses and coatings and their function.

It’s important that opticians know the best material for the job especially for groove and drill mount frames or high lens powers. We have a lot of material choices, and we must determine which combination of lens properties will produce the best lens performance for each job. For example, what are the most impact resistant and strongest lens materials? Strongest, in terms of tensile strength, means the ability of a lens to withstand a pulling force. Lenses with high tensile strength are good for drill mounts.
