LEDs (Light emitting diodes) are finding more and more takers as people believe it causes lot saving in money and reduces energy consumption. In India, the government is encouraging LED bulbs under the Unnat Jyoti by Affordable LEDs for All (UJALA) scheme launched on 5th January, 2015. According to government statistics, till 02.02.2017, 20.48 Crore LED bulbs have been distributed across the country resulting in estimated energy savings of 26.6 Billion KWh per year. It is a great achievement by the government in such a short span of time.
But there are certain negative effects too of this growing use of LED lighting and some studies say that LEDs that are too bright can harm eye retina, as well as cause disruptions to circadian rhythm. LED light could cause some people exposed over a long period of time to suffer age-related macular degeneration (AMD), the leading cause of blindness in the western world. There is debate that blue LEDs lower melatonin levels, which can weaken a person’s immune system.
First and foremost thing one need to keep in mind is avoid using cheap LED lights and always go for branded ones. It always makes sense to opt for good quality LEDs with proper warranty and safety precautions.
The human eye doesn’t handle blue light well, especially bright blue light and many LED-makers use a primary blue LED and phosphor-down-convert it to get a white LED and such LEDs may damage your eyes. If you want to be on the safe side, use blue-blocking filters, either on the lights or in your glasses.
To be on the safer side, always ensure that you, and especially your children, never stare at LEDs for really long durations of time from close proximity. It is always better to have a gap of at least 20cm between unprotected eye and light source. If needed, use dimmer switches to reduce the intensity of the light emitted by them.
Remember energy conservation is important but equally important is the protection of your eyes.
