Today is only my 3rd day wearing my 3-in-1 and I've already noticed that my last 2 nights of sleep have been much better. I don't usually have trouble sleeping, but I do work extensive hours on a computer. Using these glasses so far have changed my good nights of sleep to great nights of sleep. My recorded deep cycle on my wearable device have practically doubled. I hope this isn't just a coincidence, but usage over time will tell.
I own various blue blockers from different companies and I must share that Viva Rays exceeded my expectation. The Sol Blue Light Blocker fits me comfortably and I can wear it for hours without my temples aching. It's not too tight and it isn't too loose either. The frame has a nice heft to it and doesn't feel cheaply made. If there is one recommendation, I wish there was an option to buy frames without a built-in magnetic clip. It's a nice feature to have but I'd prefer not to have any magnets so close to my face.
