- In this episode, we will be taking a look at laser safety glass and what I have come to understand about them after many years of use various types. Also a disclaimer up front that I am NOT an eye profession (as in doctor) nor a laser safety glass expert, I am simply sharing what I have come to understand from years use and researching the topic for my own use so your mileage may vary.
Also if you want to learn more about laser safety, we have linked a PDF form Laser Vision which we recommend as well as their products too:

Your video is extremely informative! Do you have any recommendations for people with prescription glasses? Have you come across laser shields that work well for 400-450nm range and provide O.D. 6+ protection? I have the same ORTUR laser as yours in the video (5.5W output).
Wow, thank you for the review. Well explained and now I feel confident. Godbless you and your family, friend. Thanks again.
Thanks for a very detailed and informative video. What type of protective glasses are needed for the Zeus X 7 watt 450nm laser pointer?
Thanks, was very interesting and important, I wanted to know if I will close the device inside a wooden box it will protect?
Hello sir. I want to encase my laser and the metal stand in a case. I was going to use some wood but wanted a piece of laser safe plastic or acrylic sheet to go over the very top so i can see into there if needed. Can you recommend anything like that similar to these glasses?
Thank you sir! Exactly the info I was looking for.
Really valuable info. Thanks for sharing.
Well versed and informative content. Keep rambling!
Very good advise. I wonder why when you buy the ortur LM2 they give you the cheep glasses
15 watt they should be as you said OD 6 + 450/850nm
Thanks for sharing hopefully every one reads this. The last thing you want is to get retina re-attachment or worse. loss of sight.
Cheers
Very informational content. At one point I was looking at getting some sort of laser but seen the risks were to great. Thank you.
Glad it was helpful!
Just curious if you might know I’m building an enclosed for my laser and was wondering if a welding lense would be suffice as a window for my box
Thank you for making this informative video.
Very good info!
Very informative. Thank you!
I just bought an Ortur 15w laser and I plan on building an enclosure for it. Do you recommend any particular place I can find a piece of protective glass I can put on the lid so I can see in while it is running?
Thank you, great info. Unfortunately the links in the description to the PDF and your preferred safety glasses are broken.
GREAT VIDEO! My atomstack M50 10watt laser has a listed wavelength of 455nm +/-5nm. I can't seem to find OD5+ or OD6+ glasses in this particular frequency - what should I get? Many thanks!!!
How do you know if the glasses are true to their rating?
Fantastic video. Thanks!
Excelent Video! Congratulations!!
Thank you! Great information! I just received my Ortur Laser Master 2 20W and your videos are a big help for a novice like me!
Great to hear!
Where did you order from? I'm interested in getting an Ortur master 2
Best price for 20w from Amazon
@@dennisnahorney8215 no it's not, gearbest is cheaper and then aliexpress is cheapest, although I think amazon comes with the junk glasses so..
Ugh watched this and the link in the description for these glasses doesn't even work! Still don't know which ones to get.
The whole time I was waiting for you to turn on the laser so I can see how they look through the laser also I just want to know which ones to buy for my blue laser in this took forever I agree with the people that complain LOL but thanks for the video still don’t know which ones to buy
Do you have advice on protective goggles for use with a laser level rated at
Thank you, I was asking myself about the serious of the glasses who comes with the ortur.
Thank you for this critical info. I'm just new to laser, don't even have my master 2 yet. Certainly don't want to take this lighty, no pun intended. I saved this video so as to watch a few more times even to remind myself time to time. Obviously a topic not to ignore. I really do appreciate your time, short or long winded. Awesome stuff. I will check out those glasses as I ordered some other ones, but didn't understand the differences, not sure what I ordered. If I I lose 30 bucks but deal. l our eyes are irreplaceable and way more valuable. Thank you thank you, thank you.👍
Your VERY welcome! :-)
thank you for making this. :)
Great insight. Combined with video from Maker'sMuse, I now know much more I did a week ago on what to buy BEFORE I even consider lasercutter. Btw, the link to your website does not work for me as I am blocking trackers, so I have no idea what is the specific model of glases you recommend.
Looking for laser safety glasses that fit well over eye glasses, I bought the a set recommended above, but they don't fit well over my eye glasses. Thank you
Ramble or not this is important information, presented well and concisely. Thank you for putting in the time.
Great video! Goggles are necessary for work that needs to face lasers. I bought renhotecic brand goggles not long ago because I needed them, and they feel very good after use. If you are going to face laser work, it is recommended that you prepare goggles.
So would the glasses protect from all kinds of laser pointers or just one color?
Great update video 👍
Thanks for sharing 👍😀
Thanks for watching
Can you recommend a pair for over my glasses use also for a atom stack 30 watt laser
What's the best eye protection glasses for neatcell cosmetic picosecond laser. I think it is 450nm
So purchased the brand recommended in this video from amazon, largest style they have but don't fit completely over my very wide frame glasses. (Big head lol) Is it OK if they aren't against my face and I can see light from the top and bottom or do I need complete light blocking on all sides? Can't seem to find any that are more full on goggles like you would see with carpentry. Every one that is yellow or orange seems to be shaped like glasses and meant for people that don't already wear glasses. The only other ones are the red and green ones. Also does any plain transparent orange plexiglass work? Ordered a 12x12 sheet to make a housing. The glass arrived first, before the plexiglass or my engraver lol. Just not sure these ones are worth keeping for almost $50 if they don't fit properly.
Thank you for advice
Could you post a link to the glasses that you recommend? Thanks
This video ACTUALLY explains the subject!
FreeMascot OD 8+ will it work with the ortur laser engraver? This is the last piece of information before buying the ortur laser system Thanks
Any suggestions for over prescription glasses?
I just got the 20 watt Ortur. So the link you provided covers the wavelength this laser puts off?
Yes...
Very well done video, very informative. BTW it's collimated, not collminated,
Great video. Very informative....I’m awaiting delivery of the outer 15w. Will the glasses you suggest be ok. The link takes me to Amazon where they are currently unavailable.
I just checked ( diy3dtech.com/Professional_Violet_Blue_Laser_Safety_Glasses ) and they appear to be in stock. Also you will enjoy the laser I have great fun with mine!
The 15w comes with the green ones. So without knowing how strong this laser is, I assume those are not productive enough to protect the eyes?
Will these glasses allow you to see thru a strobe light shining at 800 - 1200 Lumens ?
I recommend glasses from Kentek, I bought one that covers UV and IR spectrums of lasers, including 440nm
It costs $205
Great video! I don't see the link for the glasses you recommend though.
Indeed, nice info but it actually didn't get us anywhere 😞
Would the orange glasses you mentioned be suffice for the ortur laser master 2 20 w laser?
Yes...
thanks for the info
No problem!
The link you shared for the recommended glasses is sketch city. All kinds of warnings from my web browser so I closed it. Can you put a direct link to the product or an amazon listing?
I watched the video and ordered the recommended glasses. While waiting for them to come in, I am thinking about an enclosure and two questions come to mind. 1. Can I use my shop dust collection system to suck the smoke? I am thinking that I will try that and see what happens, and 2. Is it possible to find a sheet of the polycarbonate to make a top for the enclosure so that people who walk into the shop are protected without the glasses?
Search for plastic fabricators near you. They have the capability to cut and heat form plastic. The dust collection system could probably cope with smoke from cutting wood but would offer no protection IMHO from the toxic fumes from cutting plastic. The enclosure for your laser is important as any optics are sensitive to dust.
Great video!! I want to build an enclosure, which material (transparent) should I use?
I would not use transparent save for the top, however translucent for vision pertection. I will be build a case and doing a video soon so watch for it...
I was also thinking of this. I would maybe just have a window on the top to peek in, other than that I would make it from plywood etc.
Lot's of information but all of it is valuable. I've watched several videos on DIY laser machine enclosures using colored plexiglass without any technical information about the scientific data to support it.
Excellent. Useful. Important.
Glad it was helpful!
Are the safety glasses that come with the ORTUR good enough?
That’s what I wanted to know too..
Really thankful for this valuable information.
I have a question should I buy those 15$ OD4+ glasses for a 5 watt 450nm laser.
Only if you want to risk your eyes and especially with 5 watt (output) laser. As the greater the power the greater the reflected light...
@@DIY3DTECHcom the link of product you given, they don't ship to my country.
OD4 is slightly more than enough for a 5W 450nm laser. As long as they really are the OD4 they claim to be, the light will be reduced to a safe level. If you want to pay extra to reduce it 100x beyond that, it's up to you!
anyone know if these will work with a glowforge?
Can you do research on a blue laser from hilight
Your website links are broken. Any links we can follow to get more information?
link to get the glasses does not work. Can anyone point me in the right direction?
What should I do if I can look under my googles?
I like the style of glasses that come with the Ortur Laser because they will go over my regular glasses for my eyes. I understand they are not the best, but the goggle style you recommend does not work for me. You have any recomendations on better laser safety glasses in the original style that come with the Ortur?
I wear them over my prescription glasses as an FYI...
Is this information applicable for CO2 engravers?
What about the effect on your eyes watching lasers on videos such as RUclips?
Just a heads up, the links in the description are dead (at least for me).
Any glasses you recommend for people who wear prescription glasses?
Most goggles will fit over spectacles.
Can u suggest me a glass for co2 laser
Would you happen to know where I can get glasses that will fit over my prescription glasses? I read in the questions section on Amazon and they stated these will not fit over prescription glass. Any help would be great. Your videos are great, by the way
Many thanks! Also worth note is I wear these over my readers. If you have larger glasses that would be issue and unfortunately I do not know of any commonly available glasses in this however know you can get prescription versions however they are not cheap...
@@DIY3DTECHcom my glasses are pretty small. I think I may go the camera route after some of the things I’ve read, my eyes are pretty bad already.
So have I ruined my eyes now that I have used the standard ortur laser glasses?
Do they make the safety glasses that fit over my glasses?
yes I just bought some. Often called goggles rather than glasses.
the provided link to the safety glasses does not work with two different browsers.
You show your laser without shielding when filming. Does video viewing filter out the harmful light?
I run an optical lab that basically makes prescription eyeglasses for safety and for everyday eyewear. I think this is something that is going to be needed to be addressed by optical labs to provide. From just a quick search on this, it appears that the laser safety glasses that are linked are tinted to a specific color in a polycarbonate material, most likely at 3.0mm thickness. I have my own Ortur unit coming in about 2 weeks myself. I can make my own prescription lenses in a safety frame and get the correct color tint. I'm not sure yet how that measures up until I can do some more research into this. About a year ago a student from the University of Chicago approached me about doing this but I it fell to the backburner. If you can reach out to me with more information, maybe we can come up with a real solution for those that need prescription and trying to fit these over their eyeglasses isn't working.
Interesting, however you will need someone that knows more then I check out the laser paper on the resource page as those make glasses and know what they are doing...
Not seeing a link to the glasses in the description, bud.
Wheres the link for the glasses? its blank...
would you recommend just building an enclosure with a window made of special filtered glass? How can we tell if the window is any good, or the glasses we buy on amazon are legit?
Sorry late to the party and hope you found a solution. Yes an interlocking enclosure that physically disconnects the power source from the laser when the door is unlocked is the best option, and the same applies if using a glass/plastic window, assuming the material is rated for the laser wavelength and power. For a class 4 laser, goggles are for when using an enclosure isnt feasible for your work, like when working on a laser table. I would never use any of those glasses in the video for class 4. Goggles rated for the power and wavelength of your laser, fit your face and block out all external light with a gasket/foam, thats what i would use if not using an enclosure. For extra safety i would wear the goggles when interlocking and opening the door, take off after.
@@longislanddownhill862 thank you
Sorry, might be a very silly question but could you clarify whether person standing behind closed doors would be also affected?? I have many pets, would keeping them in another room be safe?
Yes if you can not see the light your okay
@@DIY3DTECHcom thanks for replying:)
I just received an XTool D1 10 watt and it came with a pair of glass they don’t look very expensive more like inexpensive. I used them but before I had put them on I glacéd over at the laser while it was running without the glasses on I quickly turned away man for that split second it was so brite it was only my left eye. I think I got lucky I can see good. I have a little irritation in that eye
I don't see a link...just says here are my perfered glasses...
Very very in depth. Thanks so much. I’m scared to even buy a laser now haha
Glad it was helpful!
I am looking at getting an engraving laser. One of my main concerns is of course safety. Knowing what safety glasses is big concern. I asked someone at an optometrist office if they had any recommendations on selecting the correct safety glasses. They could not recommend anything specific, HOWEVER, he suggested doing a test of sorts. Place a piece of fruit such as watermelon on the target surface and place the glasses between the output laser and the target object. Then, while not looking at the engraver, flash the laser. If the target is burned or damaged, the glasses are not sufficient. It would be great if one of you experts could come up with a test of this kind. Thanks.
I am left shaking my head at this! I am sorry but this is a stupid and dangerous concept they recommended to you. Laser light is coherent light and can travel over great distances as a nearly parallel or collimated beam. What this means is that the effects can be accumulative much like standing in the sun for 10 min will not lead to a sun burn however 2 hours will. Think of the glasses much like the differing SPF ratings for sun screen. So this again is a silly concept. Second your retina is NOT a piece of fruit and can be damaged far easer. I would also suggest reading this for more information: diy3dtech.com/guide-to-laser-safety-glasses/
@@DIY3DTECHcom Thank you for clarifying. I am sorry if I gave bad information.
If you don't like the length of the video speed it up! I love your videos. They're REALLY helpful!
I wear prescription glasses do you have a recommendation for over glasses as the Ortur Laser Master will not fit over them.
Yes I wear these "over" my reading glasses...
I ordered this pair of these glasses based on the response but there is no way this pair of glasses would ever fit over a pair of glasses. The fit is tight with no adjustability and, TBH, that's probably a good thing if you're not a glass wearer. However, for glass wearers, I respectfully disagree that this is a good pair.
@@charltonwang I had a feeling that might be the case so had not ordered them I am still searching for suitable pair of glasses. Have time as not yet fitted my laser.
Yeah. I'll be looking for a new pair as well. OTG goggles seem hard to find. I even paid to import the Freemascot pair into Canada. ☹️
Will a welders hood work for laser protection?
No, laser glasses filter a specific freq of light a welding hood does not...
I bought the FreeMascot ones you recommend but they feel so cheap for $40. The build quality feels like the Chinese ones the laser came with. I hope the lens is better than the frame.
I know my question may come as ridiculous. But in case I wear two OD4 +
glasses, will it work to protect my eyes? I can't find OD 6 that ships to my country.
I am going to guess no you will not see a doubling effect..
@@DIY3DTECHcom why would you think that? Does the light remember that it already went through one set of glasses, and so it doesn't get attenuated again by the second set?
I have a 1W laser of 450nm.
Can I put a orange, yellow and red coloured films on a glass piece and will that help me protect myself against the laser?
I don't have any optical density measuring equipment. So how do I know if it's enough.
Like I'm thinking, I'll take a piece of acrylic and stick some yellow/orange/red coloured clear plastic to it. In 2-3 coats.
So will it be enough to view without wearing the glasses, as the glass itself acts like a protective shield?
Can you please help me out on this.
I'm an engineering student and I'm thinking of making a laser engraver machine.
It gets complex, however green to red will knock down a fair amount of the light. 1watt isn't that big however I still recommend safety glasses...
@@DIY3DTECHcom how can I make a protective casing then? That will allow me too see it working as well as protect my eyes.
Maybe a dumb question. Can I use glasses for welding as well? Probably won't see much 😅
Where is the link?
Thanks
Welcome
Hey! Very informative. Do you know if you need to replace the glasses after some years of use?
They should last for a long time, nothing about them is "consumable" per-say...
Do welding glasses work well ?
Yes, but no. Dark enough to protect your eyes will also block -all- the light, not just the specific wavelength, so you can't see anything around the laser either. Laser goggles allow only for example 0.0001% of the laser through, but 30% of other light so you can still see.
I have a pair I paid 40 bucks for that is the same but for CO2 light 10um range. I would pay for the ones you mentioned but I just wish they offered darker ones because honestly the blue laser, nor the CO2 laser, is really lessened in its brightness with only a 6.
I think your missing the point as these are order of magnitudes (i.e. the 6) so this is a LOT. Keep in mind the purpose of the glasses is to defuse the condensed reflected light (this is easier in the IR range then visible). Also note for the CO2 (which I have several) is when the light hits acrylic its turn heat rapidly because of its longer wave.
@@DIY3DTECHcom No, not really missing the point because they are to keep the beam from destroying your eye while also lessening how bright it is (like looking at the sun). The Optical Density numbers range from 1+ to 10+ and in spectroscopy, optical density is the measure of absorbance, and is defined as the ratio of the intensity of light falling upon a material and the intensity transmitted. The greater the OD the less light hits the eyeball (hence it being darker). 6+ is not enough for me with my CO2 and barely enough with the blue laser.
what about a shroud that goes around lazer cutter/printer is that good enough
I would still go with the glasses as it would have to be solid unless you could enough of the glass in the correct band (as you cant just colored plexi)...
@@DIY3DTECHcom thanks for the advice
I’m looking at buying a powerful laser. I’m gonna ask a stupid question. Haven’t watched video yet. But if I shine a high powered laser off in the far distance at night. Is that dangerous. Or are the glasses for if you are “burning things at close quarters” or accidental direct eye contact
Ok a minute in and I understand more. Definitely get a decent pair for anything in the 500nm range
yes shining a laser at distance is VERY dangerous as laser light is coherent and maintains its power over great distances. It worth keeping is mind glasses of this nature really are not designed for direct beam contact however reflected light only...
Most visible light lasers (common ones) are 450nm
What is the optical density of this machine? The ortur master 2 Thanks
Not sure what your asking? The glasses are 6
Optical Density (OD) is a calculation of how much of the light is blocked. 1 (full light) divided by 10 to the power of OD. So OD 1 lets 10% light through, OD2 lets 1% through. OD3 lets 0.1% through, etc. Primary goal is to reduce the optical power of the light to below 1mW, or at least below 5mW (for "blink" safety). The LM2 is
Do you recommend that i shine a 7000000000000000000000 trillion billion million WATT laser into my eyes?
Filtering and absorbing a wavelength of light are the same thing. The reason the lenses for IR appear colourless is that it’s outside the visible wavelengths.
Yes IR especially FAR IR is way out of the spectrum of visible light and I will b doing another video on that.
I bought the recommended glasses you have on this video, and at 4% power on my weak ass laser they barely block any of the light when I put the glasses in front of the laser. If I look at the machine with them on and it's engraving, it instantly hurts my eyes. There really needs to be a more reliable source of laser protection.
