Do blue light glasses really work? 


Does it seem like everyone is talking about blue light these days? There’s a reason for it. If you’re reading this on one of your screens (smartphone, laptop, tablet), you’re exposing your eyes to blue light now, though that might be a bit simplified. Blue light is just one color on the light spectrum that we’re exposed to on a daily basis.

The Proper Fit
The human eye is approximately 24 millimetres across. The Colossal Squid has an eye measurement of 27 centimetres across. That’s over 11 times bigger than our eyes! Just think how large a squid’s contact lens would be!

Luckily for them, colossal squids don’t have to worry about that, but we do.

Has your primary care provider said you need glasses, but you’re afraid they won’t look good? Do you think contacts might hurt your eyes or be hard to take care of? It’s normal to have lots of questions and feel nervous about getting glasses or contacts. However, it’s important to wear them if your vision needs correcting.
