How Sam increased Restorative Sleep by 74%
In today’s world, blue light exposure is more than just a buzzword, it’s a real health concern. Screen time is on the rise, and one high-performance golf coach decided to do something about it.
Meet Sam.
As a Golf coach, Sam spends hours with clients, while also creating videos, managing schedules, and staying connected online. But by mid-afternoon, fatigue would hit hard. Focus dropped. Sleep quality dipped. His energy wasn't quite there, and his Whoop band let him know!
To help himself, he used 2 different brands of Anti-blue light glasses, which made no improvement in his sleep. That’s when he called me and we had a conversation around trying Ocushield blue light blocking glasses, and everything changed.
“Before Ocushield, I didn’t realise how much screen time was wrecking my energy and recovery. Within days of wearing the glasses from 6PM onward, my WHOOP sleep data showed a 74% increase in restorative sleep. I woke up feeling sharper, calmer, and finally ditched the 2PM crash. Honestly, it’s one of the best tools I’ve added to my performance routine, and I recommend it to every athlete, coach or parent I work with.”
— Sam, Golf Performance Coach
The Science Behind Blue Light & Sleep Disruption
Blue light, especially in the 380–450nm range, suppresses melatonin, the hormone responsible for deep, restorative sleep. Studies have shown:
74% improvement in restorative sleep when limiting blue light after 6PM (Sam’s WHOOP data, 2025)
Delayed sleep and reduced melatonin in children exposed to screens at night (Japanese Melatonin Study, 2022)
Increased retinal stress and a higher risk of long-term eye damage with high-energy visible (HEV) blue light exposure (Obayashi et al., 2014; Ghosh et al., 2019)
Numbers don't lie. This chart shows Sam went from 2hrs 40min Restorative sleep on average over the previous 3 months to 4hrs 20min. That's a whopping 62.5% increase.
I have to be honest, as the first few weeks went by, and Sam kept sending me his stats, I didn't believe him. We tracked his next few months and Restorative sleep increased to 74%! That's Deep and REM sleep combined. He did nothing else in his routine besides wear Ocushield Blue light glasses in the evening when he got home.
That's Wild!
Why Ocushield Glasses Work When Others Don’t
Not all blue light glasses are created equal, as Sam found out. It's important to look at the scientific backing, don’t get caught up in the reviews and hype. Personally, I'd like to know how effective they are before buying a pair.
The fact is that these glasses have repeatedly shown better restorative sleep in both men and women. My wife struggled with getting her deep and REM sleep, so she reluctantly tried a pair of Ocushield glasses and within 24 hours her sleep tracker reported a large increase in her restorative sleep.
