How Infrared Contact Lenses Work: How to use them
This is a video to show you a visual of what the markings look like on the card when you wear the contacts. This video will also help show you what the vision looks like when the contacts are in your eyes.
Notice how the cards have no visual markings. Once the contact filter is over the camera it shows the markings clear as day. The contact in the video has a 9 mm filter (for the darkest kind of eyes). We find that they sell much less than the universal 4 mm filter contact lenses. We only sell the 4 mm lenses because they are the same size as the pupil so any eye color can wear them.
