Red Light Therapy for Eyes & Eyesight
A Sight for Sore Eyes
Red light therapy has been taking over our feeds – whether it’s famous faces donning sci fi masks or athletes bathing themselves in infrared saunas. Red light is everywhere. It has increased in popularity for its ability to boost skin health, smooth out fine lines, and even ease muscle tension.
But what about your eyes? Could this treatment help with vision, dry eye syndrome, or everyday strain from screens?
In this blog, we’re shedding light on everything you need to know, whether you're soothing tired eyes, supporting long-term health, or just curious about what the science says.
Scroll on to explore red light therapy’s benefits and safety tips – find out if this wellness treatment could be a bright idea for your eyeballs.
What is it again? Understanding Red Light Therapy
Red light therapy triggers photobiomodulation, a fancy way of saying it gives your cells a power boost. The extra kickstart encourages healthier cell activity, reduces inflammation, and improves circulation. It all works together for that fresher, calmer, and glowier feeling. And this can mean better resilience and improved function for your eyes.
Inflammation reduction is another big benefit. For anyone dealing with dry eye syndrome, age-related macular degeneration (AMD), or glaucoma, red light therapy could help. As for slowed disease progression? Researchers are looking into it.
Then there’s the wellness world’s obsession: collagen production. Best known for giving your skin that glassy look, it can improve your cornea and lens so it can better withstand any stressors.
So, is it even worth trying? While some experts rave about red light therapy for eye health, the research is still catching up. You should check with an eye care professional before making it a part of your routine.
What has the research found on red light therapy and vision?
Age-Related Macular Degeneration (AMD)
As one of the leading causes of vision loss in older adults, AMD has researchers searching for new ways to slow its progression. A study has shown promise by supporting retinal cell function, reducing inflammation, and improving circulation in the macula. This is the part of the eye responsible for sharp central vision. Both animal and human studies hint that this non-invasive treatment could help keep eyes healthier for longer.
Digital Eye Strain & Fatigue
How high is your screen time? Digital eye strain – also known as computer vision syndrome (CVS) – can result in dryness, discomfort, and fatigue. While a 2023 Ophthalmology study focused on red light therapy’s effects on myopia in children, it highlighted benefits for overall eye health. Giving your mitochondria a little extra power while dialling down oxidative stress might just be the trick to soothing those screen-tired eyes.
Retinal Health & Circulation
Healthy circulation is what keeps your retinas in top shape. Early research suggests it could help with managing inflammatory eye conditions, though we’re still waiting on more studies to unlock its full potential.
Amblyopia
Amblyopia, commonly known as "lazy eye," is a condition that can be improved with the right treatment. In a 2012 clinical trial, low-level light therapy was used to help teenagers sharpen their vision, with the most remarkable results seen in those under 18.
Corneal Injury
Corneal injuries can be incredibly uncomfortable and challenging to treat. This happens when your cornea gets scratched or you get something stuck in your eye.
A 2011 study revealed that red light therapy helped speed up the healing process by 42% – showing an option for accelerating recovery.
Dry Eyes
Chronic dry eyes are commonly treated with eye drops, surgery, or tear duct plugs. But now, a growing number of doctors are turning to red light therapy. It’s gentle, non-invasive light reduces the inflammation in the area. This helps to alleviate the irritation that can accompany dry eyes. Over time, this can slowly soothe and restore the moisture you’ve been missing.
Isn’t looking into the light unsafe?
Is infrared light safe for the eyes? Red and infrared light are different from ultraviolet (UV) light. The rays from the sun, or UV light, can harm your skin and eyes, leading to conditions like photokeratitis or cataracts, increasing the risk of macular degeneration. That’s why eye doctors emphasise wearing sunnies and avoiding direct sunlight.
Red and infrared light, however, have much longer wavelengths (600nm+), meaning they carry far less energy than UV light and are less likely to cause any damage. While infrared light can warm the skin, it doesn’t have the same harmful effects as UV.
How can I use red light safely for eyes?
We still recommend wearing protective goggles when using a red light therapy panel - especially when treating your face, scalp, or other body areas. And all responsible manufacturers would agree.
For other areas of your body, wearing goggles during treatment is a smart move. Here's why:
-
The heat from a red light therapy panel could be uncomfortable for your eyes.
-
The high brightness can cause temporary strain.
-
Prolonged exposure to bright light could give you discomfort if you’re light-sensitive.
When shopping for red light therapy panels, look for key features like safety settings, timers, and low heat output. These features indicate that the brand is committed to your health and prioritises your safety.
Is it worth trying red light therapy for the eyes?
Your eyes are delicate, and unless you're targeting them for a specific condition, it’s better to avoid direct exposure to red light. Always speak with a healthcare professional before considering red light therapy for your eyes – don’t attempt to self-diagnose or treat eye issues independently. It’s just not safe or worth it.
While research is still in its early stages, the results so far are encouraging. To explore the full range of red light therapy panels, check out Lumitter’s selection, which includes full-body panels, handheld devices, and targeted options.
FAQ:
Is eye protection necessary during a red light therapy session?
Even though the risks are minimal, it's always a good idea to wear eye protection during your red light therapy session. Bright light can cause temporary eye strain, making the whole experience uncomfortable.
Should I keep my eyes open or closed during red light therapy?
Simply closing your eyes isn’t enough. For complete protection, wear a pair of comfortable, high-quality goggles during your session. Although the light itself isn’t harmful, prolonged exposure to bright light can cause strain, discomfort, or glare.
Are there any risks to red light therapy?
Red light therapy is generally safe and can be used at home. However, some people report experiencing migraines, eye aches, or skin redness after sessions. To minimise side effects, always use protective goggles, avoid looking directly into the light, and set a timer before you begin to avoid overexposure or falling asleep with the device on.
Is red light bad for your eyes? Can infrared light harm my eyes?
Infrared light is a different wavelength so it's not harmful. Early research suggests that red light might help treat eye conditions like AMD, cataracts, and optic nerve damage. Since this area is very delicate, it is best to consult a healthcare professional before starting any eye-related treatments.
Can a red light mask help with the skin or darkness underneath my eyes?
Red light therapy works wonders in this area. It’s well known for stimulating collagen, helping improve skin elasticity and reducing the appearance of fine lines and wrinkles.
It also boosts circulation. This reduces puffiness and the dreaded dark circle by promoting blood flow and lymphatic drainage. Finally, you’ll see your skin start to calm with red light’s anti-inflammatory properties. Stay consistent and you’ll start to see the coveted brighter, smoother, youthful glow.
Is it bad if your vision is blurry after red light therapy?
Sometimes your eyes might be strained from long exposure to bright light. This is usually temporary and can be avoided by wearing goggles. It also helps to keep your eyes closed during a red light session. If it’s still blurry, you must immediately stop and see a doctor as there might be something else going on.
