If you're legitimately struggling with sleep/tiredness, go do a sleep study at a doctors, if you're worried about the cost of a sleep study you can buy a cheap (under $30) pulse oximeter and pre-screen yourself for several conditions (e.g. obstructive and central sleep apnea, some heart issues, some other breathing problems), and only then go get a real sleep study if you have them.
Then once you get diagnosed spend $150 on a CPAP/APAP/BiPap which you'll use for up to five years, and it will do far more to improve your sleep than some magical set of glasses or w/e these snake oil salesman are selling this week. Plus a legitimate medical device gives you useful diagnostic information (e.g. AHI level) and you can continue to take advantage of your oximeter even with the CPAP to monitor your sleep/condition.
I am just saying this is one area which medical science DIDN'T forget.
