Effect of blue light therapy

What Does Blue Light Therapy Do For The Eyes?

It is safe to say that many of us spend a great deal of time staring at computer screens. And this is particularly bad for vision. Over time, blue light from computers is linked with many problems such as blurred vision, dry eyes, cataracts, macular degeneration, and eyestrain.


Blurry vision is often a result of the eyes

becoming used to a very bright environment. In other words, the eyes begin to get used to bright sunlight, which results in the eyes taking in a great deal of heat from the screen. Over time, this can cause the tiny blood vessels that supply the blood to the retina to become fragile. When the retina is subjected to too much heat, it can become overwhelmed and start tearing. As you can see, the blue light from the screen can easily cause the onset of chronic dry eyes, one of the symptoms of rheumatoid arthritis.


Dry eyes caused by blue light exposure

are also very common among people who are exposed to very long periods of close-set screens. Those individuals will notice a gradual onset of stinging and burning sensations in the eyes as the amount of moisture in them diminishes. Not only does this lead to irritation, but can also cause blurring of vision and other problems.


However, one study conducted recently suggests

that blue light exposure may actually help treat some forms of vision problems. A group of researchers from Wageningen University in the Netherlands investigated the ability of blue light to increase the healing ability of the human cornea. They believe that it helps to increase the number of cells that are present in the photoreceptor layer in the eyes.


Because there has been much research into the effect of    

With the blue light on the eyes, it is not uncommon for physicians to prescribe short sessions of it to their patients for short-term use. They use these treatments when working on a treatment for a patient who has had surgery to correct vision problems. Another reason that physicians choose to prescribe short sessions of blue light exposure is for the treatment of cataracts and other forms of eye diseases. During these treatments, the patient must often be kept awake during the procedure so that he or she is unable to drive or operate machinery while the eye doctor works inside the eye. Studies have shown that over half of all cataract patients who used blue light therapy were able to improve or even reverse their condition within a year of their initial diagnosis.


Overall the effects of blue light

appear to work best when used with other forms of natural therapy. By exposing the eyes to the sun’s UV rays or certain colors, it can help naturally improve vision. The wavelength that the blue light waves fall into matches the visible light spectrum. In fact, people are not normally exposed to enough of these wavelengths to have any impact on their vision, although the blue light therapy sessions may trigger an increase in blood flow to the visual centers of the eyes which could lead to a visual improvement.
