Scientists also believe that excessive exposure to screens could contribute to macular degeneration, an age-related eye disease caused by damage to the light-sensitive cells in the retina. Before the digital age, people only received natural levels of any color light. Today, however, with the pervasive use of electronic gadgets, people spend hours staring at a screen, and exposure has risen dramatically. This has led to an increase in vision problems, including macular degeneration. Thats why the display screens of electronic devices such as computers, laptops, TVs, tablets, and smartphones can affect your bodys function. During the daytime, blue light from excessive screen use can increase alertness and cognitive functioning, and boost mood. But at night, it can be disruptive, interrupting sleep patterns and causing insomnia.

Nir Light Effects And Applications

NIR light dosimetry is hormetic dose-response with a curve in a bell-shape or U-shape or biphasic shape, characterized by promotion of biological process at a low dose but inhibition of biological process at a high dose. Hormetic curves are better than linear curves in accurately predicting biological responses under pharmacological threshold 30. It is very important since stimulatory responses from NIR light are mild, ~ 30% to 60% above controls. In contrast, traditional dose-responses are usually increase by several folds. The hormatic dose-response is well known in various NIR light applications, because photo–stimulatory or photo-inhibitory effects are shown in low or high energy densities respectively 31. Positive responses can be achieved in the dose range for desired therapeutic outcomes 16, 32, 33.

Whats Led Light Therapy

LED stands for Light Emitting Diodea type of light that is clinically proven to aesthetically improve all Fitzpatrick skin types.

You might hear people talk about what colour theyre using on their skin, but its the frequency of light that matters. This is whats able to penetrate through your skin and encourage regeneration on a cellular level.

Simply shining a red light on your face wont do the trick, and heres why. LED Light Therapy helps improve the appearance of skin by altering cellular activity.

Dr Andrew R. Christie explains how it works, The mitochondria absorb the light. They become energised. And this energy encourages a process for these cells to think, act, look, and behave like younger cells. When these cells undergo mitosis , it creates further similar cells.

In this article, were talking about the safety and benefits of the following frequencies used in Dp Dermaceuticals L.E.D.:

  • Red light 630nm
  • Near-infrared light 830nm

Is Red Light Therapy Effective


Most experts say that they dont know yet if RLT is effective for all its claimed uses. Most say that the studies published so far show some potential for certain conditions, but that more studies need to be conducted. Red light therapy is still an emerging treatment thats generating growing interest. But at this point in time, theres not enough evidence to support most uses.

The gold standard of studies to determine if a product is effective is a randomized, placebo-controlled trial. This means that a certain number of people with the same range of characteristics get either the study treatment or a placebo for treatment of the same condition. Some studies also include a comparison to another commonly used treatment. Results can then be compared between the emerging treatment versus no treatment or versus a current standard treatment.

Many of the published studies using RLT included only a small number of people, didnt include a placebo group, werent conducted in humans or were limited to cell tissue itself. Most researchers say results so far look promising, but that more quality studies with larger numbers of people are needed.

This has important implications for glaucoma and possibly other eye conditions.

But what of red and near-infrared light? As with any light, there is potential for photoreceptor damage . However, treating the eyes with red light therapy can be done safely and without damage to the eye. It comes down to two factors: length of exposure, and wavelength.

How Does Light Affect Your Sleep

Light plays a key role in your circadian rhythm and how well you sleep.

Your circadian rhythm is your internal 24-hour clock. It helps you feel sleepy at night when its dark and it also makes you feel alert during daylight hours.

Light exposure provides your brain with information that guides your circadian rhythm. In a natural light pattern, your circadian rhythm follows sunrise and sunset. But our world is filled with artificial sources of light that can throw us off this natural cycle.

Several studies suggest that light exposure at the wrong time can disrupt circadian rhythm and potentially impact your health.

When your circadian rhythm is off, you can end up in a vicious cycle. You cant sleep well at night, and you feel tired and in need of a nap during the day.

But there are a few ways you can use light to help get your rhythm back.

Those who struggle with dry eyes due to meibomian gland dysfunction can greatly benefit from red light therapy, according to some findings. In a clinical trial of 52 patients with MGD, 90% reported relief from their symptoms after trying red light therapy.

In this study, red light was used to treat dry eye symptoms using a special red light-enhanced device. Patients placed the device over closed eyes for three minutes at a time at least twice a week. After three months of this practice, they reported relief from discomfort such as grittiness and burning sensations.

Other studies on the topic have produced similar results, though additional data has yet to be reviewed.
