Spectra479 Fit-Over Blue Blocking Amber Glfor Sleep - Nighttime Eye Wear - Special Orange Tinted GlHelp You Sleep and Relax Your Eyes

It's highly recommended if you really care about your eyes, specially nowadays with the extended usage of LCD screens. I am using it as stand alone glasses.

I was able to sleep well after using this product. The tint is not too strong and not too bright. Just enough for my reading habits.

Glasses are solid, well packaged, will buy more of these

These cut out at least 90% of surrounding light. They sit at the same distance from the face as normal glasses; there are slight margins that are uncovered such as the lower outer edge but these don’t cause a problem. At the top edge of mine there’s 3mm of space above my iris (5mm if I have let them slide down) and 1 cm at the outer corners. I don’t think you could expect much more coverage without having a rubber-sealed-underwater-mask type set-up. Rooms can have either central overhead lights on, or side lamps. Ater popping these on about 2 hours before bed, I tend to go for side lamps if I’ll be there for 15 mins+ and main lights if there for 10 mins or less. The great thing is, if watching a screen with others, the brightness settings can be left as normal for them, while I still have the benefit of greatly reduced blue light. I haven’t found a problem in darkened hallways when there is a little light from another room … I can still see well enough, though I ensure any dark bags are either off the floor or tucked well to the side eg the large one that I use for online returns and my Husband’s work bag. Wouldn’t be without these, now.

I have to tell everyone how great these glasses are. They are so sturdily built. I cannot live without them, so I have a few pairs just in case I forget one in a hotel or somewhere else, but so far, I haven't. I take them with me wherever I go as I love to watch TV with them. I have a great way to avoid those awful, bright, blinding hotel lights. With these glasses, my evening at any hotel is so COSY now. I find that I can sleep so much better since I got them, and I have had them for years already. My husband loves his pair as well. We both use the same size, and they mysteriously fit us both so well, even if our faces are very different in shape and size. I have dropped mine a few times, and they are still working great. My oldest brother used to tear at night while watching TV, and I gave him a pair of these glasses, and it corrected his problem. No more blue light damaging our eyes and our emotional self. I find that I feel so much calmer and happy at night when I wear them.

Muy buenos, si bloquean la luz, hice varias pruebas además de comparaciones con otras marcas y esta es una gran opción pues cumplen con la función a buen precio

Delivery took 10 days but refund is taking more than that. These glasses will fit only on half frame specs.
