These simple frames are sized specifically for smaller faces and are easy to slip on and off. They’re also lightweight, so your child may feel less irritation while wearing them.
Controlling light exposure isn’t something our pre-industrial, pre-digital ancestors had to worry about. But in today’s perpetually lit-up world, it’s important for us all to regulate how we consume light–and the timing of light our consumption. Light has tremendous effects on sleep and health, and too much light, especially in the evenings, can seriously undermine sleep.
Blue light, we’ve learned, is especially detrimental to sleep and health, when we’re exposed to too much of it and our exposure comes at the wrong times of day and night.
What is blue light? It’s the shortest wavelength of light on the visible light spectrum. Sunlight contains blue light, along with the other visible light wavelengths. Both energy efficient and digital lighting contain high concentrations blue light. It’s not that any and all exposure to blue light is harmful. But because of our constant exposure to digital screens and bright nighttime environments, most of us are consuming way too much blue light—and doing so at the at very worst times for sleep.
The good news? A large and growing body of research demonstrates that blue light blocking glasses can be highly effective at filtering out blue light and restoring healthy sleep and bio rhythms.
Studies show wearing blue light blocking glasses can:
- Improve symptoms of insomnia
- Increase sleep amounts and sleep quality
- Reset circadian rhythms
- Improve cognitive performance, including memory and learning, and how quickly the brain processes information
The best times to wear blue light filtering glasses:
- In the evening, before bed
- When using computor screens, phones, tablets, TVs etc
- When in environments where artificial lighting (such as flourescent / energy efficiant light) is causing stress and overstimulation. This can be in places such as shopping malls, supermarkets, and sometimes even in classrooms and our own homes.
- Wear bluelight blocking glasses all the time
- Or wear them outside (light from the sun does contain bluelight, but a certain amount of it is ok, and light from the sun is good for us ... just don't go and stare at it for a prolonged period of time!!)
Other methods to help with digital eye strain
Before you buy, it's a good idea to consider the fact that while bluelight blocking glasses reduce the amount of blue light we consume, they don't reduce the eyestain that we experience when we frequently stare at something for prolonged periods of time (aka focusing fatigue). Here are some other ways to get relief from digital eye strain symptoms:
- Get a comprehensive eye exam. If your kids are suffering from blurred vision, eye fatigue, headaches etc, it might be time to go and see an optomitrist.
Minimize the glare on their screens.
Replace your old tube-style monitor (called a cathode ray tube or CRT) with a flat-panel LED screen with an anti-reflective surface.
Adjust computer display settings.
Blink more often.
Get them to exercise their eyes - Another cause of computer eye strain is focusing fatigue. To reduce your risk of tiring your eyes by constantly focusing on your screen, look away from your computer at least every 20 minutes and gaze at a distant object for at least 20 seconds.
Take frequent breaks.
