Juniperus offers a large selection of colored lenses with different light filtering properties. Our standard colors are Red 550 and Ruby Red 580. These colors are edge filters, which means they block all wavelengths below a certain threshold, that threshold is 550 nm and 580 nm respectively.
We have a filter for every time and purpose. Choose a filter based on your personal situation and preference. That is, usage and light environment. Deciding between Red 550 and Ruby Red 580? If you have to spend time in a well lit place during the evening or at night go for the Ruby Red 580.
