These are excellent. I work at home in the evenings a couple a nights a week, and have noticed such an improvement to my physiological and mental states going to sleep and waking up the next morning having used these. The night-time settings on phones and computer screens are no match for these!!!

The clip-ons are surprisingly slimmer than what i thought they would be and the colour shift isn't too bad either. Will definitely wear these on top of my glasses in the office as well (the fluorescent lights are horrid!) awaiting my 50% blue blocking prescription lenses.

I can confidently say that these glasses have significantly enhanced my quality of sleep. I typically wear them for 1 to 2 hours prior to bedtime. After about a month of consistent use, I have noticed that I do not wake up as frequently throughout the night, and my sleep is much deeper and more restful. I also say that if I need to get up during the night, I am able to return to sleep more easily, as I feel naturally drowsy with the glasses on. Previously, it took me a considerable amount of time to fall asleep again due to my early morning wake-up schedule (I used to have to wake up at 3 am).

These glasses are lightweight and fit comfortably over my glasses. Though I have previously tried other brands, I can confidently say that these glasses are superior in their ability to improve my sleep quality. Overall, I am extremely satisfied with my purchase and consider it a wise investment in my overall health and wellbeing.
