These glasses were recommended by my doctor because I was having trouble falling asleep and staying asleep throughout the night. I find myself feeling more calm when I wear them at night while watching TV or being on my phone and I fall asleep much faster. I also get migraines and when I wear the glasses, the pain feels more dull and less intense. These glasses are an investment and if you can afford to make it, they are worth the money.
I ordered the Ram Dass Sunset to wear when I watch TV at night. I could tell a difference when falling asleep. I ordered a second pair of day time glasses because I am on a computer all day long.
I went to the Auto Show where there was a lot of artificial light and was wishing I had them on.
Amazing. Wearing blue light blockers before bed is a life changing experience.
The unboxing and quality of my red pair was top notch. You can tell they take the time on the details. Wearing the red lenses at night really helps with getting to sleep quicker. I wear them watching tv etc. I also noticed I sleep through the night at a better rate. Highly recommended!
Very effective. Been easier to relax before going to sleep
