Blue light is a phrase we tend to hear a lot these days, and while you probably know it has a negative connotation, do you know why? Exactly what is blue light, how bad is it, and how can we block it??

NEGATIVE IMPACT ON SLEEP (and Health):
According to Harvard Health Blog, blue light (which may or may not be perceived as the color blue) is visible light with a wave length between 400 and 450 nanometers. It is a concern because it has more energy per photon of light than other colors in the visible spectrum. They say that blue light from screens such as your computer, tablet, and cell phone, is not strong enough to contribute to macular degeneration or blindness, but it can still have a negative impact on your health by stimulating your circadian clock and keeping you awake or disrupting your sleep.
Some studies have suggested a link between exposure to any bright lights at night with increased risk of cancer, diabetes, heart disease, and obesity, with blue light being the worst offender.
Proposed ways to counteract the effect of blue light on our sleep cycle and overall health include:
A report by AOA (American Optometric Association) explains that extended use of cell phones, tablets, and personal computers can lead to symptoms of dry eyes, blurred vision and headaches, and suggests the use of amber-tinted or blue light blocking lenses when using screens directly before bedtime can help limit their effect on sleep.
PLAY IT SAFE!!
We are just starting to venture into the study of blue light and personal screens' effects on both adults and children, and we have SO much to learn!! For now we are mostly hearing various "links" and "assumptions" rather than proven cause & effect... I don't know about you but in this type of situation I like to play the whole "better safe than sorry" card.
What's this mean?? Having my children and myself avoid personal screens 2 hours before bedtime. But let's face it... for myself, it's not all that practical. I usually have to get on at night after the kids go to bed to catch up on work and to send some quick emails. Not to mention to watch TV and scroll through social media. You know how it is... This is where blue light lenses come into play!
Blue Light Blocking Glasses
I've been an ambassador for DiscountGlasses.com (DG) for a few years now, since my youngest needed "indestructible" glasses at age 3 (see that ADORABLE unboxing review video at the bottom of this post). We LOVE DG for glasses and sunglasses for our entire family! It wasn't until very recently I realized the potential health benefits of adding a blue light blocking coating to the lenses (whether prescriptive or not), so I did just that with my most recent order!
Check out these Lunettos Clarkson frames I just got - how cute are these!? The basic frames with prescription are $39.95 (with free shipping) but I got the following add-ons:
This is my first ever glasses of any kind with blue light blocking lenses and honestly, there is zero difference in respect to how I see out of them and how they look, which is great! They're not colored. I really have no idea how they work but again, better safe than sorry!! I typically don't wear glasses for computer use, I only wear prescription sunglasses while out because I can't see distance (signs, etc) but now I plan to wear these blue light blockers at least when on screens in the evening... but maybe more? They SUPER cute, and so lightweight! I really love them!!
If you're nervous about ordering glasses online, don't be! DG hase free shipping, 365 day free returns, virtual try on for most frames, and you can even renew your prescription with their free online vision test!
