That’s a small point. The larger point is people’s lifestyles. While there may be a small subset of the population that is especially sensitive to blue light for most people it comes down to your lifestyle and how and when you are exposed to light. More blue light, specifically sunlight earlier in the day is better. As evening approaches dial back your exposure to blue light. Same with the content you consume. Read the social media and bad news in the morning, less in the evening.
