Computer Reading Glasses Blue Light Blocking - Reader Eyeglasses Anti Glare Eye Strain Light Weight for Women Men

I LOVE the glasses. Was worried because of the cost but, it is worth the money! The glasses are so delicate and light. You can feel the quality. BEAUTIFUL! Delivery took much longer than expected, but I am so happy with the glasses that I couldn't take a star away.

I've been using these as computer glasses for about a week now and am mostly happy with them. Here's why.THE PROS: The 1.75 magnification I ordered was perfect, and I can see clearly through the entire range of the lens. The glasses are lightweight, and with the integrated nose brace, I don't worry about nose pieces falling off. They came with a hard case, a polishing cloth, and a tool set. Yeah!THE CONS: There are no springs in the earpieces. The ear piece hinges seem a bit tight. I'm not sure this is a con, because experience with similar hinges in the past has ranged from the screw loosening and falling out to the screw working itself so tight it eventually caused the earpiece to break off to the screw and hinge joint remaining perfect through the life of the glasses. Only time will tell how these pan out.THE QUESTIONS: The lenses are clear, yet they claim to block blue light. I did about 40 minutes of online research, and was unable to find a definitive answer to whether clear lenses are capable of blocking blue light. Manufacturers say yes, writers with opinions but no facts say probably not, but I couldn't find any independent laboratory tests confirming this one way or the other.The bottom line for this Blue Light Blocking capability - which is why I bought these particular glasses - will be after I spend a long day at the computer, do my eyes burn and feel tired? They haven't yet, so maybe they work fine.All in all, considering that reading glasses like this range in price from about $3 at your local mega-mart to more than $200 from places that are inordinately proud of their offerings, the ~$33 I spent on these seemed a decent value for the money. Although for this price, I hoped they would have spring hinges.

My blue blocking reading glasses are now the only ones I wear! They are attractive, lightweight and neutral. I love the opportunity to discuss the benefits of wearing blue blocking glasses to my friends.. melanopsin - In humans, melanopsin is found in intrinsically photosensitive retinal ganglion cells (ipRGCs).[6] It is also found in the iris of mice and primates.[7] Melanopsin is also found in rats, amphioxus, and other chordates.[8] ipRGCs are photoreceptor cells which are particularly sensitive to the absorption of short-wavelength (blue) visible light and communicate information directly to the area of the brain called the suprachiasmatic nucleus (SCN), also known as the central "body clock", in mammals.[9] Melanopsin plays an important non-image-forming role in the setting of circadian rhythms as well as other functions.

I was pretty skeptical about glasses being able to filter blue light and bought this pair as 4.0 reading glasses. After a couple weeks of use, however, I realized that my eyes do not hurt anymore. I spend all my time at work in front of the computer and read books on ipad at home (also, surf internet often) and my eyes were beginning to hurt real bad. Not any more! Pretty amazing. Of course, 4.0 was also a big help, but the not-hurting-anymore effect is unexpected and very welcome. Of course, this is very individual, but it worked for me.

I first bought a pair of these a couple years ago to use for watching TV with my husband. I had cataract surgery and now my eyes are more light sensitive. He loves watching TV with the lights off and I found I was getting headaches while watching with him. I figured it was blue light, got a pair with 0 magnification, started wearing them for TV, and headaches/eye strain gone. For the cataract surgery, I got graduated vision distance lenses implanted which let me see middle and far distance. Before that, I was pretty myopic - now it’s reversed. Because one eye is middle distance and one is distance, that means I have different prescriptions for each eye for readers. I got a pair of blue-blocking prescription readers for regular use. But, I also wanted a spare pair for next to the bed so that I could read at night, read labels in clothes, that sort of stuff. I have a pair of wire-rimmed readers with nose pads which are okay. But nose pads really bug me. Plus, wire frames always end up getting bent out of shape in tiny ways that eventually make a huge difference to comfort and visual acuity. So, I got a pair of these in 1.5 magnification as my spare pair. They’re light, the frame doesn’t present much contrast, and they block blue light really well. I especially like that the frame is bendy and they don’t have nose pads digging into the bridge of my nose (especially when it’s allergy time and my sinuses are swollen). Like most off-the-shelf readers, the magnification isn’t perfect and that’s made worse by my uneven eyes. But, they’re 1/10th the cost of prescription glasses and only intended for occasional use, so they’re good.
