To filter or not to filter? A guide to blue light.

To filter or not to filter? A guide to blue light.

The myths, rumours, and dubious facts surrounding blue light are plentiful as the light itself.

Blue light sits towards the UV end of the visible light spectrum, which means that in the day time, there is abundant blue light around, and in the evening that amount is significantly reduced.

Some associate blue light with being bad, but this is not the case. Bright light, including our blue friend, causes the body to release serotonin and cortisol, both of which make us feel awake and active.

The problem can arise when we are exposed to an unnatural amount of blue light at the time when our body is meant to be powering down and preparing for sweet, sweet sleep. How does that occur? Phones, iPads, laptops, all those things we stare at for hours each evening release blue light into our bedrooms. Our advice is that if you have trouble sleeping it might be worth trying blue filter lenses. Or you could watch less Netflix, but you’re only human.

Some believe that blue filter lenses prevent disease, but there is no research that proves this to be true. Some people also believe that it helps them sleep better. Again, this is unproven and could well be a placebo, but if ‘Night Mode’ isn’t helping, it’s might be worth a try.

We encourage our customers to make up their own minds when it comes to blue filter lenses, and avoid the hubris, however cerulean.

If you’d like to try blue filter lenses, the cost is £50 - if ordering frames online, email info@cubitts.co.uk for more information.
