Red Light Therapy Lamp: Is It Harmful To The Eyes ?
Red light therapy is the use of low-level red light wavelengths to treat a variety of conditions, such as joint pain, acne, wrinkles, and even depression. It works by enhancing cellular energy production and promoting circulation. Many people are turning to this type of treatment to improve their health, but some wonder if red light therapy lamps are bad for the eyes.
To answer this question, we first have to understand the type of red light used in therapy. The red light wavelengths used in the treatment are lower energy and contain no ultraviolet (UV) rays. Unlike ultraviolet light, which can cause photokeratitis (sunburn of the cornea) and also damage the retina, red light therapy lamps do not emit any harmful radiation.
However, it is important to note that looking directly at a red light therapy lamp may cause temporary discomfort to the eyes. Bright light can cause temporary damage to the retina, which can cause temporary blurred vision and other visual disturbances. Therefore, it is very important to wear protective glasses or keep your eyes closed during treatment.
Another issue to consider is the duration and frequency of treatment. It is recommended that red light therapy lamps be used for a limited time of 10-20 minutes at a time and only a few times per week. Prolonged red light therapy can cause eye strain, which can lead to headaches and eye discomfort.
It is well known that red light is beneficial to the health of the body, especially the eyes. The most widely used therapeutic wavelengths are red light (630-660nm) and near-infrared light (NIR) (810-850nm). Light therapy uses a light-emitting diode (LED) device that shines red or near-infrared (NIR) light into the eye: a painless and safe method of red light therapy.
Too much screen time can also contribute to macular degeneration, an age-related eye disease caused by damage to the photoreceptor cells in the retina. Before the digital age, people were only exposed to natural light of any hue. Today, however, with the widespread use of electronic devices and people spending hours staring at screens, exposure has skyrocketed. As a result, visual impairments such as macular degeneration have increased. As a result, the displays of electronic devices such as computers, laptops, televisions, tablets, and smartphones can have an impact on your bodily functions. During the day, blue light from excessive screen use can increase alertness and cognitive function, while also improving mood. However, it can be disturbing at night, disrupting sleep patterns and causing insomnia.
Since red light is absorbed by the outermost layers of the body, it is ideal for treating conditions of the eyes and skin surface, such as chronic skin diseases and hair loss. It can still pass through relatively thin eyelids, but not through a lot of bone or muscle.
On the other hand, NIR has a higher absorption rate. It promotes the healing of strokes, wounds and diseases by stimulating stem cell formation, reducing inflammation and promoting the healing of strokes, wounds and diseases. These two forms of light combine to activate every area of the eye, even when the eye is closed.
Red and near-infrared light diffuse to the retina similarly to blue light, but have no known harmful effects. Red and near-infrared photons activate mitochondria (cell energy centers) to produce more adenosine triphosphate (ATP), or cellular energy. The more energy your cells have, the better they will perform, repair and rejuvenate themselves.
Another advantage of red light therapy is that it reduces inflammation, especially eye irritation. This condition can occur after an eye injury or a problem caused by constant pressure, and can damage eye tissue. When eye tissue is injured or destroyed, vision loss or even blindness can result.
In conclusion, like other light treatments, red light therapy lamps are not harmful to the eyes if used properly. Knowing the correct duration and frequency of treatment sessions and wearing protective glasses or keeping your eyes closed during treatment is critical. With the right precautions, red light therapy can be a safe and effective way to improve your health.
