![]() When comparing the contrast/detectability of stains under UV from PeeDars with clear UV safety spectacles against cheaper 390+nm flashlights with amber/yellow spectacles we found zero tint to be more useful. Deep brown or metallic tints seemed universally useless for stain hunting, simply making vision darker all-round. deep reds of orange juice) they may be harder to spot wearing tinted glasses. Unfortunately if backgrounds give off a yellowish colour, or there are stains that glow quite differently in color from yellow (e.g. Urine glows under UV usually have a strong light yellow/amber colour and so pass straight through yellow/amber tints. If using 390+nm flashlights amber/yellow tinted spectacles are effective at filtering out most of this problematic visible purple light, therefore letting you see stain glow contrasts against their backgrounds. Cheaper UV lights, on the other hand, those that use 390+nm, tend to emit a large amount of strong visible (non-UV) purple light which covers the stain and background with the same intense purple colour, less contrast means stains are harder to detect. If you bought a PeeDar, or PeeDar 2.0, safety spectacles don’t appear to enhance fluorescence, all tints we tried (amber/brown/rose) actually reduced our ability to see stain glows against their backgrounds. We investigated this claim and found that this is only the case with less expensive 390+nm UV flashlights. ![]() Due to there being the potential, however small, of damage to eyes from UVA and UVB wavelengths we recommend going with the safest option of wearing a quality pair of 99-100% UV-protective, or UV400 (filters nms of 400 and below), plastic glasses.Īdditionally, customers often hear that UV safety spectacles come in tints that actually enhance fluorescence. The obvious question here relates to what ‘minimal’ refers to, as you can imagine the potential for UV damage varies a lot depending upon for example, your skin type (fair, or dark), exposure time and the type and quantity of UV light, amongst many other factors. Black lights tend to emit longer, much less damaging wavelength light somewhere in the range of 360nm to 405nm, the danger posed by them is considered minimal/non-existent depending upon who you talk to. UV wavelengths of 320nm and below are known to be harmful and the wavelengths to really watch out for. UV flashlights are considered to be weak sources of UV compared with direct sunlight or commercial tanning beds. A slightly longer and fuller explanation follows. It is always better to err on the side of caution. Do I need UV glasses when using black lights? The short answer, to what is a complex and still quite a grey area is, yes. Please read further for answers to the following 3 bolded questions:ġ. We decided to try and create a useful resource to refer back to when contemplating the need for UV protection whilst stain hunting with any black light. Our PeeDar range of specialised UV urine detecting flashlights provide a real bang for your buck, and after seeing the power outputted customers often ask about whether eye protection is required. ![]() Hence they are great for detecting pet stains.UV is an incredibly effective light source for detecting a wide variety of invisible stains, as well as creating some intriguing visuals. Newer money has been equipped with florescence of bands that show up under a black light.Īnyone who’s watched a crime show is probably aware that body fluids show up under a black light. Here is a UV marker you can use to protect your property. Depending on what you want to use it for, you may opt to pay more for a larger one. There are many options for black light flashlights. This is what makes a black light flashlight useful. All you need to know is that there are many things that have phosphors. Phosphors are any substance that absorbs energy and re-emits it as visible light. It makes any item glow if it contains phosphors. Without boring you with a bunch of scientific stuff, basically a black light emits ultraviolet rays which are invisible to the human eye.
