Diode Laser Eye Protection & Why You Need To Upgrade

Using those cheap, cheesy glasses that came with your laser? Not as safe as you think. Do you wear corrective lens glasses and then try to wear those cheap ones over them? Here is a better and safer solution.

Best explanation I've seen yet!!! Thanks!

[@GoodYearForLiving]

These diode lasers have flooded the market. I've hardly seen any safety information in these diode videos. Thanks for the video.

[@007JHS]

Great clip, helpful... I've just taken delivery of my Sculpfun 10W laser... before I even assemble it I want to buy two additional pairs of eye protection.

[@shadowmaster8122]

Thank you for a very good video. One thing to take note of. Sometimes the goggles are rated Different ratings at different wave lengths. I believe on the goggles that you have. Some frequencies are OD 7+. And some frequencies are OD 3+. My laser engraver is a 455 nm. When looking at the wavelength graph for the goggles, In that range I believe that the goggles are an OD 3+. They are also labeled as 3+ for the 190 nm to 540 nm. For my 5.5 W laser. I believe an OD 6+ would be needed. Take Care.

[@CarkeekW]

Well this is a highly underrated comment that deserves 100 more likes , agreed OD3+ at best in the working range of his laser and I would be looking for better if possible , I believe this has something to do with the crossover to visible light spectrum so the glasses will allow you to see around you while using them.

This a review of your "suggestion" for SAFE glasses? What's your response / opinion? I was going to order those glasses U suggested - but now? My eyes are too important to chance - so? Reviewed in the United States on October 27, 2021 Style: Fit-over Frame 4Verified Purchase So: let’s just start from why I waited so long to review these. I got them as a backup set in case I was with someone else who didn’t have some. I didn’t want to use them or loan them to anyone until I could properly test them with a Multiwave Laser Power Meter and some different Diodes - along with my trusted goggles and a camera. That day finally arrived yesterday and today when the Power Meter got in and tested to be working properly. I only bothered testing it with 405nm Violet and 450nm Blue diodes - because the results were completely disturbing. Not only did the majority of the light pass through mostly uninterrupted, but the light that didn’t pass straight through didn’t really get absorbed: most of it just got refracted/detracted and it actually wound up reflecting some of this as invisible UV light (which I couldn’t measure the intensity of these UV beams since they would go in different directions that were hard to predict with the curvature of the lenses and the environmental conditions: but suffice it to say that on my camera they looked far more substantial than a beam from a high end laser pointer you would attach to a rifle for hunting). It’s scary how bad these performed. I would not trust this brand in the future. I even measured the reflection of the beams off of a black surface, and dark brown wood surfaces into the Power Meter and it still was letting a completely unsafe amount of the 405 and 450nm beams through unabated. Which is crazy. I wouldn’t even feel safe using these with something as dinky as a 50mW diode. These are an example of people taking advantage of your willingness to trust claims and not verify since they make you feel safer - when in fact it may make you less safe since you may be less careful or vigilant with these on, falsely believing that you have a layer of decent protection I watched and some what trusted your review - but now - one comment has changed my trust in any "paid' review"!

[@rogersshop]

THIS IS NOT A PAID REVIEW!!! I BOUGHT THESE WITH ADVICE FROM A LCENSED OPTOMETRIST. In addition, these are certified for use with the types of lasers i work with. they are NOT INTENDED TO MAKE THE LIGHT BEAM INVISIBLE.

I know this video maybe getting old but, can you please answer a question for me. I'm having a hard time with a neighbor. He's shooting me with a laser at night when I go out to see what our whom is in my backyard. Can you think of a way I might catch him on some sorta media? Maybe a film which would burn easily at the hit of a red laser or blue that has been used lately. Would one of small cameras you can attach to a cellphone catch him beaming me? Anything you can think of might help me. Thanks you.

[@rogersshop]

A regular cell phone camera should easily capture that, even at night.

[@thebosun181]

Wise words

[@timthayer9365]

Thanks for the video, Roger!

[@robertoclemente9051]

Hello Roger, I ask you a question, in the video it seems that the laser is working, and at times you don't have your glasses on, and on the other hand, if you have the laser working, you attend the 3d printers with the protective glasses on to prevent reflections? Greetings from Argentina!

[@rogersshop]

My lasers are shielded and unless I am looking directly at it, I do not wear the goggles unless doing glass or mirrors. Otherwise, there are no reflections.

[@Kayakasaurus]

Hey, I’m getting a laser next week and I’m concerned for my safety. Have you gone blind yet? 😅

[@rogersshop]

No, not at all. Been wearing corrective glasses since 1965, but am careful around lasers.

[@David.....]

Those green glasses are to ENHANCE visibility of the laser in daylight, not protect your eyes.

[@SamBatti88]

Hi, I’m building my own diode / co2 laser and need help to find material to use for enclosure. Need real safe material that stop diode or co2 laser wavelength. Ideally 4mm thickness and bright black :)

[@corruptduboiscountyindiana5058]

How do we know if we have a laser powerful enough to worry about casual play? I dont trust the power labels on the pointer

[@rogersshop]

One should never look directly at a laser beam, regardless of stated power, without eye protection rated for that wavelength

[@corruptduboiscountyindiana5058]

@@rogersshop i use one to play with my cats all the time. Its green and says 532nm on the sticker. The only time i really feel anything in my eyes from it is when i point it at a glass door knob which scatters the light all over. Then it kind of hurts my eyes.

[@davehimlin2374]

what do you suggest to wear for 532 nm - green laser - 500 milliwatt output ?

[@rogersshop]

From a liability standpoint, I can't. Consult an Optometrist.

[@dsdufour]

Hi Roger excellent video, I have a question. I bought a pair of safety glasses before I saw your video and now I'm wondering if I got the right glasses. I'm using a creality falcon 2 22w, the laser light is orange. The glasses that came with the laser are green. And bought orange ones (190-490nm) are these safe.

[@manuelcanedo8772]

Hi Roger, this is a great video. I just want to ask You something cause I have viewed and read so many articles about shield protection for lasers. I am building a safe enclosure for my laser (450 nm) and I would like to know what is the difference between acrylic (PMMA) and approved safety acrylic like jtechphotonics. I know that the orange color aids in blocking the blue laser light (455nm) used by diode lasers, so is not enough to buy an orange acrylic like the ones Amazon sells very cheap: instead of approved safety acrylic. The difference in price is huge and probably have the same product, with different marketing. Thanks, Manuel

[@rogersshop]

I'm pretty sure there is a difference between plain orange acrylic and that listed to be used as a shield for the particular wave length. I'm not a specialist in plastics chemistry............

[@orion95467]

​​@@rogersshophello sir,Im looking for a blue laser pointer 450 nm and i have the glasses you are using here between the chooices to buy,so these ski style googles by mcw are right for a burning blue laser pointer 450 nm? Orange lens can block also red and green lasers or i must choice another color lens? What lens is required to stop green laser pointers light? For a 450 nm blue i would need at least AN OD5+ 6+ but I would prefer an OD7 if aviable,its a laser pointer diode not a machine so i will not have to watch the beam from so close distance like you do on the video,does these googles defend your eyes so much from the light? Does these orange lens block the infrared if present? Im new about these things so I don't know much about the argument i hear cheap green lasers have an infrared issue,so im seearching someone whit experience that can guide me to the right choice,

[@rogersshop]

@@orion95467 Contact an optometrist, From a liability standpoint, I can't answer your questions.

[@orion95467]

@@rogersshop ok but we can be agree for blue laser the color lens you need is orange

[@rogersshop]

@@orion95467 Correct!

[@SteveO2027]

I was also looking at these that you linked to but the description says they are for "Fiber Hand-Held Welding" is this just a mistake on Amazon??

[@rogersshop]

Not a mistake, but also in the same protection wavelength metric.

[@SteveO2027]

Thanks noticed that these are OD3 rated for 455nm lasers is that good enough or is it safer going for OD6 version they do for 455nm lasers?

[@rogersshop]

@@SteveO2027 Optical density 3 (OD3) is adequate for diode lasers in this wavelength. OD6 is better, of course, but also much denser, and if orange, you will not be able to see the blue diode beam much, if at all.

[@9401766]

Hi Roger, do you know which goggles will work with a 60-watt CO2 laser, Thank you!

[@rogersshop]

You will need to know the wavelength in NM, then find glasses or goggles listed for that wavelength.

[@SodiumSyndicate]

Should I use Eagle OD4 or OD6 Orange eye protection goggles with a 450nm 1.7 Watt Blue Laser?

[@rogersshop]

The higher the optical density rating (OD), the better, so OD 6 is better than OD4

[@SodiumSyndicate]

@@rogersshop Does higher OD rating mean we cannot see rest of the environment clearly as well, or is the non laser environment not affected in terms of shapes (while color range being blocked)?

[@rogersshop]

@@SodiumSyndicate My goggles are OD7 and it does not interfere with being able to see things around the shop, other than anything blue is now much muted and more of a gray.

So the first 1 star on your link attached states the user has purchased these and also purchased a tester of sorts, and these gasses seem to have failed. Can this be touched apon?

[@rogersshop]

These WORK. I give pretty much zero thought to some amateur with their own "test set".

[@amoreyjones565]

So red would be better than green

[@rogersshop]

Not really. Orange is the proper color for a blue diode laser.

[@WARVIATION]

I bought a 5,000mw laser, it came with those cheap red glassses, would it be safe if I wear those and look at the point at another side of the room for only a few seconds?

[@rogersshop]

Depending on the brand of laser, some have adequate shielding for the occasional glance. Otherwise, wearing safety glasses or goggles designed for this type of laser is recommended.

[@WARVIATION]

@@rogersshop ok thank you sir!

[@BlooketGoat]

I need laser goggles for a 74W 455nm laser diode array. Do you have any recommendations for good laser goggles to buy? I also noticed that in the product picture for the OD7+ laser goggles, it says that the laser goggles are for OD3+. Is this a mistake? Or are the laser goggles actually for OD3+?

[@rogersshop]

Mine are OD7+. I did not see where there was any reference to it being OD3. From a liability standpoint, I can't say "These are perfect for you". Best to check with a certified optometrist.

[@BlooketGoat]

I unfortunately do not have access to a certified optometrist. Also, in the product page video, it shows multiple angles of the laser goggles. In a few of the angles, you can see printed on the upper part of the googles OD3+. I know this is asking a lot, but could you prove the goggles work with your laser engraver? Maybe in a video showing what the laser point looks like with and with out the laser goggles. You could also show the cheeper laser glasses, and show how they aren’t as effective at protecting your eyes.

[@HappyHappyPanda88]

apparently colour of the glasses doesn't say it all, experts chip in please.

[@Maverick-jn9ur]

Hello Rodger, I got the Karono/Carlany laser safety goggles orange on amazon for $28.44usd. Could you please let me know if those are okay to use with the class 4 blue lasers? I got them but I am seeing a little bit of floaters after using them and I'm not sure if its because I used a dispersion lens and didn't use my goggles because the light seemed pretty dim or if the goggles aren't that good since its made in china. Thanks.

[@rogersshop]

Check the specifications. Should be at least 1064nm 532nm 355nm OD7+ CE. The OD rating is also important. The higher the number, the better. The 1064nm is for CO2 laser and the 532nm/355nm is for blue diode laser.

[@UPXMail]

your choice is F for fiber lasser. not blue. i think you are not safe..

[@rogersshop]

You are wrong. Look it up. Wave length.
