How it works
These orange tinted glasses should be worn for 1-3 hours before your ideal bedtime to block the blue rays associated with delaying your body's production of melatonin. These orange-tinted glasses only eliminate the blue component of light so you will still be able to read, watch television and use your computer or smartphone. The UVEX blue light blocking computer glasses are perfect blue light glasses to eliminate the sleep performance drain from the UV lights from computer screens from staying up late in front of your LED monitor/laptop/iPad.
Blue Light Blocking Glasses are suitable for both indoor and outdoor use. These patented light restriction glasses are for adults with average size heads.
Why is light so important to the body for sleep?
Light is one of the most important external factors that can affect sleep. It can making it difficult for people to fall asleep, and it can influence the timing of our internal clock and thereby affecting our preferred time to sleep.
Light influences our internal clock through specialised "light sensitive" cells in the retina of our eyes. These cells tell the brain whether it is daytime or nighttime, and our sleep patterns are set accordingly.
Due to the invention of the electric lightbulb in the late 19th century, we are now exposed to much more light at night than we had been exposed to throughout our evolution. This relatively new pattern of light exposure is almost certain to have affected our patterns of sleep. Exposure to light in the late evening tends to delay the phase of our internal clock and lead us to prefer later sleep times.
How have Blue Light Blocking Glasses Improved Users' Sleep?
A number of people with longstanding insomnia (persistent insomnia) have reported being able to develop a normal sleep pattern by using blue light blocking glasses.
Most people with sleep problems who purchase the blue light blocking glasses find they begin seeing a benefit within a few days. It may depend on how far they need to shift their circadian rhythm. Stimulating an earlier flow of melatonin by blocking blue light in the evening is accomplished by advancing the circadian rhythm (setting the internal clock to an earlier hour). This is similar to accommodating to a time zone change (jet lag) and requires a day or two for each time zone change. If you are used to going to bed at 1:00A.M., and want to get to sleep at 11:00 P.M., it may take at least two evenings of putting on the blue light blocking glasses at 9:00P.M. Moving the circadian rhythm an hour per night may work better than trying to move back the internal clock all at once.
Why Bright Light Exposure is Important in the Mornings
While restricting bright light exposure in the evenings may help you fall asleep, it will not significantly shift your sleep/wake pattern as much as exposure to bright light in the mornings (or whatever time you are wanting to be awake and alert).
According to research out of Flinders University, it is the exposure to the blue/green light (at the right time of the day) that has the most effect in shifting the circadian rhythm. There is a stronger link to melatonin levels in administering bright light than there is in filtering it. In simpler terms, if we want to feel tired at the right time, we also need to make sure we are feeling awake at the right time.
If you can't get bright sunshine in the morning, consider the Feel Bright Light to reset your internal clock.
