Product Information:

In the finale to our KLIM product reviews, we're taking a look through some glasses in order to set our sights on the KLIM Optics.

When you use any device with a screen, you’re staring right into the blue light that's constantly being emitted from it. Though many of us spend countless hours staring at our phone or computer screen, it’s not exactly the healthiest thing to do for our eyes. Not only can it cause strain and headaches, but there’s a good amount of studies out there that claim that too much blue light can throw off your circadian rhythm. Software solutions such as f.lux exist, but for those that want to take things one step further, there’s tinted glasses that are built to help minimize eye strain.

As someone who is prone to headaches while spending excessive amounts of time staring at a monitor, yet does not wear any form of eyewear, I was immediately curious about the claims made by KLIM and their Optics line of blue light blocking glasses. These little glasses block up to 86% of blue light, quite a bit more than similar products, including a majority of Gunnar Glasses, the most well-known competitor in this market.

The moment I removed the glasses from their fancy case, and unfolded them to put on, I was a little shocked at how drastic the difference was. I didn't gain magical MLG gaming skills, but I did notice how everything turned a warm yellow tone, far more than I expected. My desktop background, normally a bright blue, suddenly had a different tone, with most blue elements looking as if they'd been straight up removed. Stark white text on black backgrounds or bright white webpages became much easier to handle, especially during the evening, when my surrounding lights were dimmed.

For those that have prescription eyewear, KLIM also offers a clip-on version called the OTG, which attach to the front of any regular pair of glasses in order to provide the same blue light filtering as the Optics. Both of these are quite effective, as I noticed that wearing them during the evening did legitimately help subside the mild headaches I'd been having. They're also comfortable to wear and feel well-made, having a nice matte frame that's light enough to not feel noticeable after hours of use.

At just under $40, these are around the mid-range price tier for blue light filtering glasses. They're not as stylish or flashy as the pricier versions, but they're also much more subtle, meaning you might feel less embarrassed to wear these in front of others. It's also more than likely that buying the cheaper variants won't result in glasses with as strong a lens, or will be ones that won't last long due to cutting corners on build quality. Overall, I'm quite pleased with the KLIM Optics. They're not going to change your life, but for their price, they are a great option if you're someone who spends their day looking at a screen and want to take measures to protect your vision.

Verdict

What We Liked ...
  • Comfortable and lightweight
  • Alleviates eyestrain when worn
  • Does its job of blocking blue light
What We Didn't Like ...
  • While it cuts down headaches for me, they might not be as effective for others
8.5
out of 10

Overall

For what they're advertised to do, the KLIM Optics excel at blocking blue light, are more than comfortable, and while your mileage may vary, they cut down minor headaches for me when reading lots of text on my computer.

I got some of these (well, they're a different brand, but they're identical - mine are made by Duco, bought off Amazon.co.uk)...
I've been sufferring from increasingly more severe headaches, dry eyes, and sleep patterns being out of wack, and decided some 'blue light reduction' was worth a try. I have no other issues with my eyesight; I've never required glasses or contact lenses, but these symptoms have been growing in severity for a number of years.
For my job I sit in front of a Mac retina display for a minimum of 8 hours a day, at home I spend a varying proportion of my time looking at my phone or tablets screen, my LED PC monitor, or my 49" 4k tv... after just 48hrs with a pair of these my headaches had reduced and my sleep returned to a more normal routine.
If you suffer from any of those same symptoms (and others, like migraines) I'd certainly recommend considering trying a pair of these.
 
Why dont just use blue light filter programs?
Or iirc win10 has this feature already.
That's great for when you're on an OS that supports a filter app/prog... but what about when you're on your Vita/Switch/3ds? How about your tv (and all the consoles you play via that tv)? All LED light sources produce blue light - is there a filter for car headlights, or home/office lighting?

I think the color makes the difference
Right

White light is made of green, red and blue

If you take away blue, you get red and green - which in light theory create yellow

Therefore it is impossible to make a blue light filter that is not yellow

they do make clearish varients that are a lil yellow or have a film over the lens to block the blue light. they are used by digital artists

I'm not entirely sure how a piece of software could "block" blue light, blue light is generated by the LED backlight. Most diode-powered backlights use blue diodes doped with yellow phosphorus. The blue light excites the layer of phosphor, which in turn changes the diode's colour to white. That's the cheapest way to manufacture them, but the yellow phosphorus doping quickly deteriorates, giving the screen a blue tint over time. You can certainly reduce it by adjusting the strength of the backlight and the colour spectrum, but you can't eliminate it. This is why monitors come with a blue light filter pre-installed as one of the layers of the panel, but some find the stock filters insufficient. There's no magical software solution that eliminates blue light emission short of just switching the backlight off completely, which defeats the purpose. Not only that, monitors are not the only source of blue light - your energy efficient LED bulbs are emitting the same kind of blue light, so these filters are quite multipurpose.

In that case they are blocking less blue light

You'll note these block way more
nah bro they block out high energy blue light which is known to be the spectrum area that affects us the most. the yellow/orange lenses are just archaic and cheaper to produce

If you block light that is high energy enough that we can't see it, then it is UV light - and not properly blue light

All blue light absorption filters are somewhere on the spectrum between yellow (least absorption) and red (complete absorption), amber seems to be a good middle ground. Dichroic blue light filters can be clear as the filter film is extremely thin and only visible at certain angles. More advanced clear glasses are actually self-tinting, meaning they're covered in a photoreactive compound which changes its properties depending on how much light it's exposed to. Those tend to block a range of spectrums, from blue light to UV.

the blue light that fatiques us and causes eye strain is uv light. ever look at a uv bulb? it's blue because our eyes aren't fancy enough to see the exact colour.
 
Ultra violet BLUE or UVB light. I'm sorry if that confused you
I'm not confused, the "B" doesn't stand for "blue". The spectrum we consider to be UV is divided into three ranges - UVA, UVB and UVC. There are some more specific categories like vacuum UV and so on, but the basics are just those three. "B" doesn't stand for "blue" , much like "A" and "C" don't stand for any particular colour, it's simply a designation of the width of the wavelength. UV light is actually completely imperceptible to the human eye, it's not within the visual spectrum. It is, however, often accompanied by a blue or violet glow from the near-UV spectrum which we do see, plus most UV lamps we come across are covered in protective coating which makes the "blue glow" more pronounced.

To supplement what foxi4 said, it is called ultraviolet because it is above violet

Similarly infrared is inferior to red

Visible light is sandwiched by radiation imperceptible to humans

If these bands above and below visible light were regular colors we wouldn't give them special names - we would just call them "blue" or "red"

    I rather enjoy a life of taking it easy. I haven't reached that life yet though.
