These clip on clips are very effective at blocking blue light. I've only used it a few nights but I think it's already helping with my sleep pattern. So far I've only really used the night until about 2 hours before bed, and I seem to wake up less at night and fall into a deeper sleep. I have tried daily lenses, they are comfortable to wear and do not interfere with clear vision. Time will tell if this is a long-term solution; I suspected that exposure to electronic devices at night was negatively affecting my sleep. These clip ons (both day and night versions) are fairly well constructed and of high quality and will fit a variety of glasses but not all. Fortunately, the shape and size match my own glasses very well. Can't give 5 stars yet as I'm not sure if this will be a long term solution; Another factor holding them back from a 5 rating is that they probably won't fit all goggles and the clips, while sturdy, are a little thick and my nose basically rests on them so it's a little less is more comfortable than it could be. I believe there will be 5 of these and they are perfect for goggles that support this feature. The clips are well packaged and come with protective sleeves and a cloth pouch for your safety.
