No. Thousands worldwide avail of light therapy every year without any negative effect. There is no evidence that standard light therapy (properly administered to people with normal visual function) is harmful to the eyes. However if you have a history of visual difficulties apart from wearing glasses (e.g. cataracts, ulcerated cornea etc) then be sure to consult with a doctor before undertaking light therapy.

Bright light therapy involves the regular (usually daily) exposure to a bright light source. Treatments typically involve an artificial light source of accepted therapeutic intensity and having peaks in specific wavelengths, with exposure duration of a set period and distance from the light source.

Bright light therapy has been extensively researched at leading institutions worldwide for over 25 years. Most people experience no side effects; however, some individuals may experience minor side effects (headaches, eye strain, and occasional nausea) that tend to disappear after the first few days of exposure. Bright light therapy has proven safe and highly effective when used under the supervision of a trained clinician or physician.

Experiments indicate that individuals who suffer from Seasonal Affective Disorder (S.A.D.) are affected by light, which plays a major role in the secretion of melatonin. Melatonin is a natural hormone made by your body's pineal gland. This is a pea-sized gland located just above the middle of the brain. During the day, melatonin levels are barely detectable in individuals who don't suffer from S.A.D.

Very few people report side effects from receiving bright light administration. Some people may initially experience slight eye stress or a headache, which tends to dissipate the longer the exposure to the light. Re-Time® Jetlag Glasses™ emit light of about 1200 lux intensity into the eyes of the wearer. As a comparison, on a bright sunny day the brightness looking toward the horizon is about 100,000 lux.

Officially there is no connection between using a computer at work and vision problems. However it is interesting to note that employers in the UK are legally obliged to give free eye tests to computer users and pay for basic lenses if required. It is common to suffer from eye strain or dry eyes after a day at a computer screen. Many people believe that their vision problems started or got worse when they began to use a computer regularly.

The optimum time for taking light therapy in the morning is best gauged by determining the onset of melatonin in the evening. In external clock time, this can differ by several hours between individuals, and using the light too early or too late will greatly reduce its benefit. Melatonin is a nighttime hormone. At a certain point in the evening, levels of melatonin begin to rise because the biological clock has told the pineal gland in the brain that produces melatonin, 'Now it's night.

Light therapy is the shining of bright light into your eyes, typically for a half hour each session. Mood & Sleep Disorder clinics recommend 10,000 lux light levels Since the 1980's, light therapy has become the first line treatment for Winter Blues and SAD. Bright light can also be used to shift your circadian (wake/sleep) cycle, so it is used to prevent jet lag, minimize work shift change fatigue, and help abnormal sleep phase insomnias.

Light Force Therapy uses light emitting diodes or LEDs to produce a unique combination of frequency and wavelength of safe low-level infrared light, which helps to elevate muscle tissue temperature and increase circulation. All of these factors are essential in relieving discomfort and relaxing muscles, making Light Force Therapy extraordinarily effective. Light Force Therapy is free from dangerous UV and laser rays.

Laser Therapy or "photobiomodulation", is the use of specific wavelengths of light (red and near infrared) to create therapeutic effects. These effects include improved healing time, pain reduction, increased circulation and decreased swelling. Laser therapy adds energy to living systems. While we are able to explain many of its molecular and biochemical effects, it also adds energy at atomic and subatomic levels.

Response to light therapy is usually very quick, and most people will notice a marked improvement within one week. Most people similarly experience a rapid recurrence of symptoms if they stop using their bright light system. Longer trials have also shown increasing response to light therapy after two weeks, with still more incremental improvements after three or four weeks.

Most people with Winter Blues are likely to respond well to bright light. If your symptoms are severe, you may suffer from SAD. Light therapy may work well for you, but you should consult your clinician before choosing any therapy. The Visor can be used along with other treatments - for example, with antidepressants for SAD. Likewise, most people will respond to bright light for circadian rhythm adjustment - i.e., jet lag, shift change work and some insomnias.

Bright light at 10,000 lux is within the range of light we experience almost every day - from a dimly lit room of 100 lux to a sunny day outside of 40,000 lux. Eye exams of subjects receiving up to 20,000 lux have revealed no risks. Bright lights may cause some people to "see spots" for a short period after use. These "spots" normally disappear within a few minutes. Elderly people may take longer - up to 10 minutes - to return to normal.

You never want to expose your skin or eyes to the light from a UV system. UV light is non-visible however it can be harmful, similar to the harmful effects of UV light from the sun. UV lamps can actually cause a severe sunburn-like effect if skin is exposed for long periods of time. Always ensure that you are wearing some type of protective glasses (ie. Safety glasses or sunglasses) when working on a UV system and the lamp is exposed.

Intense Pulsed Light (IPL) therapy is an effective way to rejuvenate the skin, giving it a more youthful appearance. Light-based treatments use a less-intense, broader spectrum of light than lasers, but are effective in treating rejuvenation of the skin. Candela's Ellipse I2PL is the only light-based product that is built specifically to dual-filter light as it is absorbed, thereby generating more consistent results.

Yes. There is no extra charge for this. The foot switches, as well, the film file slots on the console are standard features on every model.

This one has been beaten around a little. Some people claim looking at the Sun induces sneezing, others say it impedes a sneeze: Sneezing, Sun Sneezes, sneezing, and Sneezing and bright light

NOAO does not keep track of unexplained phenomena in the sky, so I cannot tell you for certain what it is that you saw. However, there are several possibilities: First of all, it could not be a supernova because they become very bright for weeks to months, not just for a few seconds. Supernovae that are bright enough for the naked eye to see are also very rare. If the object was moving, there are a few possibilities.

Camera man has testimony of a Trucker on his video who got immediate help with his Muscular Dystrophy: "Any doctor that says Reflexology doesn't work is full of Bullshit and needs to go back to medical school and learn something." SHOWTIME Camera Crew pauses after shoot to reflect on Trucker response with M.I.R. VP Rachel Brinkerhoff. Quack Buster took on a hot challenge when he belittled stress as indefinable.

Night light power is reduced to a level that makes it easy to see where you're going at night. A light bulb for a standard night light will provide about 20 lumens of light in a 360° sphere. Since PowerSURE safety lights are a point source directing a beam of light from a wall in a much narrower field, we've found that approximately 1 lumen is plenty of light for night lighting purposes.

in the description for night lights, we've set the power of the LED for power failure light to approximately 4 lumens. This is very bright for the human eye and we do not recommend looking directly at the light when it is on during a power failure.

In order to protect your eyes, the light is diffused through a UV filter to take out the light that causes you to tan. However some UV rays do get through though not enough to give you a tan. To put things in perspective, you will be exposed to far less UV light from a light box than you would be from going outdoors, even on an overcast day.

Blue and Red light therapy is effective for about 86% of people, so there is a very good chance it will work for you, too.

Light therapy involves exposure to intense levels of light under controlled conditions. The recommended light therapy system consists of a set of fluorescent bulbs installed in a box with a diffusing screen and set up on a table or desktop at which one can sit comfortably for the treatment session. Treatment consists simply of sitting close to the light box, with lights on and eyes open.

Recent studies show that light therapy can be helpful year-round for people who experience chronic depression, unpredictable recurrent depression, or bipolar depression, and the method has been effectively tested in patients using medication and even electroconvulsive therapy. The addition of light therapy to the regimen must be under doctor’s supervision.

Prolonged, direct exposure to the light waves from a UVC bulb is harmful to all living organisms, including people. However, the air purifiers have been designed with safety in mind. Do not look directly at the UV bulb.

Its just a light. It is set at a frequency that activates the silver ions but it is as harmless as any light in your home.
