Prof. William Dalton, Ph.D.Understanding when you require blue light glasses will prevent eye strain and sleep problems from becoming severe. Do you notice any of these signs? After spending long hours in front of a screen, do you experience constant discomfort? Do you find it hard to fall asleep even when exhausted? These indicate your eyes need protection from man-made light influences. Taking care of them early on will result in greater ease and a superior quality of sleep.
Visual Discomfort Patterns
- Dry, gritty eyes after two hours of screen time
- Increased blinking or squinting during device use
- Light sensitivity in brightly lit environments
Sleep Disruption Signals
- Lying awake for over 30 minutes after bedtime
- Frequent nighttime awakenings despite fatigue
- Relying on sleep aids regularly
Productivity Warning Signs
- Declining focus during afternoon work sessions
- Increased errors in screen-based tasks
- Avoiding necessary computer work
Office workers are usually the first to notice a decrease in productivity in the afternoon. It takes less time than others without protection before they lose their concentration. Work that involves detailed use of the screen becomes increasingly difficult. It is time to conclude that the eyes need the defence of artificial light. This was my own experience before I came across blue blockers.
Screen-driven headaches normally begin behind the aching eyes. They spread to the temples usually after prolonged use of an electronic device. They differ from tension headaches in that they are sensitive to light. If it becomes the routine to take over-the-counter painkillers like Advil, then some protective lenses may help. The clients I deal with report an 80% reduction in discomfort when using proper eyewear.
Suppose you experience sleep onset latency despite feeling exhausted. In that case, this is a sign that your circadian clock is out of balance. Artificial light tells your brain not to release melatonin. This can cause you to feel a tired-but-wired feeling on a nightly basis. Taking over 30 minutes to fall asleep consistently indicates you need to complete a protective protocol. Wearing red colors before bed usually helps alleviate this.
Children indicate in a different way than adults. Some persist in rubbing their eyes when doing homework. Others will not read on the tablets at all. Others become irritable during evening screen times. These changes show the need for protection for developing visual systems. Start with amber lenses during homework hours.
