New York, NY – For many years researchers have released warnings about the danger of sunlight to the eyes. And doctors have consistently, and wisely, recommended eye protection for outdoor use during daylight hours. Yet, strangely, some lighting manufacturers are still making claims that lamps duplicating sunshine are good for vision and eye health.
According to research, blue light accounts for just one part, or 400 to 500 nm, of visible light. Emitted by sunlight, artificial lamps, computers and mobile screens, blue light has a very short wavelength and produces a greater amount of energy. The danger is that blue light increases the amount of toxin in the macular region of the eyes. It accelerates the crystalline lens turning yellow, and finally makes it gradually whiten and evolve into cataracts.
Studies have shown that senior citizens and children under the age of 14 are the most susceptible when it comes to harm from blue light. Office workers and students who use artificial lamps may also be at risk of developing blurred vision, cataracts, age-related macular degeneration or vision loss. And other studies have found that blue wavelengths suppress delta brainwaves, which induce sleep, and boost alpha wavelengths, which create alertness. Blue light can cause sleeplessness at nights.
There’s a great deal of evidence and scientific research showing that exposure to UV and blue light can damage the retina and health. But people have a tendency to ignore the blue light hazard from artificial lighting compared with that from their mobile phone or computer. The truth is that people work, read and study with lamps for long periods of time and should be more attentive to the type of lamps they choose.
Below are some tips from professional eyes doctors to choose the healthy and safe lamps that prevent blue light hazard:
- Correlated color temperature (CCT) range of 3000K-4,800K (“warm-to-neutral white”) for eye safety and best contrast
- Color rendering index (CRI) of at least 80 for good color perception.
- Brightness range of 1000-2000 LUX at 12 inches (30 cm)
- Dimmable to alleviate eye strain
- Easily adjustable fixture to prevent glare
- Easy location and operation of fixture controls
- Coverage diameter of at least 12 inches (30 cm) at a distance of 12 inches (30 cm)
- Sturdy construction for safety and durability
Doctors and scientists at Dr. Lite Medical LLC have been working on a solution. With ‘Medical Grade Technology,’ harmful areas of blue light are filtered out, while beneficial types of light are allowed through. The Dr Lite Lamp results in increased alertness, focus, and visual acuity.
The company’s products have been field tested by ophthalmologist Dr. Terry Forrest of Waynes Memorial Hospital at N.C., and are endorsed by MDSupport.org.
