text: FAR too big for your face if you have bought and used the BluBlocker clip on. Blublocker needs to add some smaller size glasses to the collection.  I'm near sighted so I can't use my eyeglasses with the Blublocker clip on to watch tv or look at a computer screen at night. SLEEP DISORDERS:  unless you have orange lenses to block out blue light, you should avoid looking at tv screens, computer screens, iPads, smart phones, etc. for a few hours before bed.  Those screens transmit a blue light that stimulates a part of your brain that will interfere with you falling asleep.  This color lens blocks that blue light.  These help me with Sleep Phase Delay Disorder. My sleep disorder neurologist never mentioned this, but from my research, there is plenty of science supporting this.
