I absolutely LOVE my Nate Daylights! I work remotely so I wear them every day, they are so cute, comfy, and easy to wear. I have a smaller face width and they fit great. I feel they really make a significant difference. I am a Ra Optics fan through and through and also want to note that their customer service is top-tier. If I could give more stars I would!!!
Good so far. Helps with blocking my sensitivity to devices and fluorescent/LED store and home lighting. Can use as sunglasses if forgot yours. I wear them if using any devices.
I was indecisive about whether to get these because of the price tag, but I’m really glad I got them so far. I have very dry eyes and concerns about screen usage and hope this is just one key to improve the situation.
I got the circadian set and have felt an extreme difference. I work fully remote and stare at screens all day. It has drastically affected my sleep and my focus. After using the circadian set I have been falling asleep so much faster. Highly recommend!!
These are great for working night shift in a hospital! So much harsh blue light. These are perfection!
Hi Sarah, We are very grateful for your review and very happy you have the daylight glasses to protect you from the harsh hospital lighting. Thank you for the work that you do in caring for others. Kind regards, Jacqueline
Finding yourself inside, staring at screens day and night? You need to protect your health from the damaging effects of all that artificial blue light. Ra Optics glasses are scientifically-proven to block 95-100% of artificial blue light, saving you from poor sleep, eyestrain, headaches, and feeling fatigued.
For years I searched for a treatment that would heal - not mask - my underlying health issues. What I uncovered changed everything about the way I thought about light, sleep and my health. Keep reading to learn how Ra Optics’ Blue Light Blocking Glasses have made all the difference.
We started with science then made it stylish. Our glasses have been developed with leaders of photoscience, neuroscience, and optics. They are infused with pigments that have been tested and retested for effectiveness. We personally know they work, but many leaders in health and fitness can attest to that too.
