I have another pair of evening Vivarays but wanted the ones for daytime while I have to work at my computer. I really really love the Dusk Magnetic Daytime Blueblockers. I am so happy I purchased the magnetic ones because I want to get the evenining (Orange) to go on these. They are so light and comfortable on my face.
Using these while working inside and then the orange ones after sunset has been life altering for me. I sleep like a baby. I'd rather be outside with my feet in a river all day, but in the meantime, these make being indoors tolerable.
