The lighting industry has standards upon which we can reference concerning LED light energy and safety. According to the IEC standards, IR light at a wavelength of 850 nm light should not exceed 10 mW/cm² if exposure time will exceed 1000 seconds to be considered safe.
Are infrared LEDs safe?
Infrared, visible or ultraviolet electromagnetic radiation, in sufficient concentrations, can cause damage to the human eye. To date, Light-emitting Diodes (LEDs) have not been found to cause any damage.
Is infrared light damaging to eyes?
Prolonged exposure to IR radiation causes a gradual but irreversible opacity of the lens. Other forms of damage to the eye from IR exposure include scotoma, which is a loss of vision due to the damage to the retina. Even low-level IR absorption can cause symptoms such as redness of the eye, swelling, or hemorrhaging.
Is infrared light the same as LED light?
Light therapy is one of the oldest modalities used to treat a variety of health conditions. … Infrared therapy involves the use of infrared radiation to produce local heat; whereas LED therapy is a non-thermal therapy used in a variety of dermatological processes, and wound healing.
Is infrared light damaging to skin?
UV radiation is considered most dangerous for skin. … New scientific research has revealed that one third of infrared (IR) light can penetrate into the deeper layers of the skin, triggering heat induced responses such as inflammation, hydration loss and the degradation of collagen and elastin.
Can you go blind from infrared?
Yes indeed, infrared light (the wavelengths beyond those of red light) can be very harmful to your eyes even though you don’t see them. The same applies for ultraviolet light (the wavelengths beyond those of violet light). You can read more under the topic of laser eye safety.
Can you look at infrared light?
Science textbooks say we can’t see infrared light. … Like X-rays and radio waves, infrared light waves are outside the visual spectrum. But an international team of researchers has found that under certain conditions, the retina can sense infrared light after all.
How can we protect our eyes from infrared?
CSA Class 1-4 safety eyewear fitted with an appropriate lens will provide protection from UV or IR radiation where a moderate or large amount of shielding is required. The Standard allows for the use of spectacles, goggles, welding helmets, or welding hand shields fitted with the appropriate lens.
Can red light therapy improve vision?
Summary: Staring at a deep red light for three minutes a day can significantly improve declining eyesight, finds a new study, the first of its kind in humans. Staring at a deep red light for three minutes a day can significantly improve declining eyesight, finds a new UCL-led study, the first of its kind in humans.
Can infrared light damage the pineal gland?
VERIFY: There’s no evidence infrared thermometers harm a part of the brain called the pineal gland.
Does infrared light stimulate collagen?
These results suggest that infrared radiation may have beneficial effects on skin texture and wrinkles by increasing collagen and elastin contents from the stimulated fibroblasts.
What is the difference between infrared and red light therapy?
For starters, infrared saunas use heat to work, whereas red light therapy emits almost no heat. As we talked about earlier, infrared saunas heat your body through the use of far infrared wavelengths. … Red and near-infrared wavelengths give your cells energy without the stress on your cardiovascular system.
How often should you do infrared light therapy?
Everyone reacts differently, depending on their age and the condition of their skin. In general, best results are achieved over an 8 – 12 week period. It is recommended to start with a commitment of 15 minutes, which is the maximum time in our Red Light Therapy bed, at least 3-5 times per week for the first 1-4 weeks.
What are the harmful effects of infrared?
IR, particularly IR-A or near IR [700nm-1400nm], raises the internal temperature of the eye, essentially “baking” it. Medical studies indicate that prolonged IR exposure can lead to lens, cornea and retina damage, including cataracts, corneal ulcers and retinal burns, respectively.
Is infrared heat good for your skin?
Intense infrared radiation, or heat, has been shown to be detrimental to the skin. Heat increases the production of melanocyte pigment within the skin, so it can worsen melasma and other skin pigmentation concerns.
Does infrared light therapy really work?
Infrared therapy is a safe and effective way to reduce pain and treat a wide array of conditions. It seems to be a safe, effective, and drug-free way for long-lasting pain relief. It also helps to heal injured body parts.
