People associate blue light with computers and digital devices. But the greatest source of blue light actually comes from the sun.
While there is no scientific data showing that blue light from digital devices can cause any harm to your eyes, exposure to blue light can cause digital eyestrain and disrupt your sleep.
Digital eyestrain occurs because people blink less when looking at screens, which causes eye strain and dry eyes. Blue light helps to regulate our circadian rhythm by waking us up and stimulating us. So late night exposure to blue light from your phone or computer can make falling asleep more difficult.
Eye care professionals recommend observing the "20-20-20" rule to help reduce digital eyestrain. This involves looking at an object at least 20 feet away for at least 20 seconds every 20 minutes. You can also use artificial tears or take dry eye supplements such as Dr. Krawitz's Dry Eye Relief¬Æ TG-1000
to help soothe dry eyes. Glasses that are touted as helping to protect your eyes from blue light have shown no clinical evidence that they are effective. Therefore, the American Academy of Ophthalmology does not recommend such eyewear.
The carotenoids lutein and zeaxanthin increase macular pigment and improve contrast, which can help to reduce glare. These compounds are found in VisIVite¬Æ macular degeneration supplements, as well as the athlete's vision supplement, RBI Vision Performance¬Æ
