Blue/HEV light- How to best protect your eyes!

With the continuous use of technology in our everyday life it can be hard to take the precautions necessary when using these devices to protect your ocular health .It is important, with the continuous use and exposure to blue light through our tablets, smartphones etc. that we consider lenses with an Anti-Reflection Coating to protect our eyes through-out our everyday activities. It is important that we outline the benefits Nikon SeeCoat Blue has to offer to us.

An overview of the Nikon SeeCoat Blue. Nikon SeeCoat Blue was the first coating available in Canada with a blue light filter. The purpose of the SeeCoat Blue coating that is available on most of the Nikon lenses is that they are meant to protect against blue/HEV light. With today’s advanced technology it makes it almost impossible to avoid the effects of blue light, with things like tablets, HD Televisions, smartphones readily available to us.  In order to maximize the comfort you may have with prescription lenses, the SeeCoat Blue UV filter works to do so by minimizing the amount of glare reflecting off of the blue light surface. The SeeCoat Blue filter design is designed in a way that the front and back coat is added in a way that works to eliminate between 380 nm-500 nm of blue light and helps to limit the amount of HEV/Blue light that reaches the retina to protect your ocular health. Some additional advantages that are included in a Nikon lens with the SeeCoat Blue UV filter is that they are overall more durable lens, two times more scratch resistant then a conventional everyday ARC coat lens. On top of all those features, the Nikon lenses also make it possible to keep the lenses cleaner by being dust resistant, making it easier to clean and reduce the frequency of cleaning the lens.

Blue light - protection

Prolonged exposure to blue light for long periods of time, can also add to eye strain, fatigue and reduce contrast. It is important that we protect our eyes as much as we can and to also further prevent complications in the future, as there has been evidence of Age Related Macular Degeneration and/or Cataracts forming after continuous exposure to blue light over a lifetime. Blue light can also affect people in the following ways short term, such as the effects of blue light contributing to sleep problems arising from the exposure by disrupting the bodies’ biological clock by potentially reducing the amount of melatonin produced. With lower levels of melatonin within the human body it can also onset the probability of developing cancer.  What is recommended when using technology is to take frequent breaks, and put away all electronic devices 2-3 hours before bed.  Also use dimmer lights such as table lamps to cut down the amount of blue light they may transmit before going to sleep.

Although blue light has shown negative effects on the body at night. The positive effects during the day the blue light can help people to stay more alert; it can also enable them to have faster reaction times and increased their overall mood.
