Frequently Asked Questions
What’s the difference between blue light blocking glasses and polarized glasses?
Blue light blocking glasses are designed to filter blue light emitted by digital screens such as phones, laptops, and televisions. Polarized glasses are mainly used outdoors to reduce glare from sunlight reflecting off surfaces like water, snow, or roads. ESSANTIALS glasses focus on protecting your eyes from digital screen exposure.
How do blue light blocking glasses help with sleep?
Blue light from screens can suppress the production of melatonin, the hormone responsible for regulating sleep. By filtering this light, blue light blocking glasses help your body maintain its natural sleep rhythm and make it easier to relax and fall asleep at night.
Why do many athletes and footballers use blue light blocking glasses?
Many athletes use blue light blocking glasses to improve sleep quality and recovery. Proper sleep plays a key role in performance, focus, and muscle recovery, and reducing blue light exposure in the evening helps athletes get deeper and more restorative rest.
Do blue light blocking glasses help with eye strain?
Yes. Long hours in front of screens can cause digital eye strain, which may lead to tired eyes, headaches, and blurred vision. Blue light blocking glasses help reduce this strain by filtering harsh screen light and making digital viewing more comfortable.
