Blue light is everywhere around us. Cell phones, computers, televisions, and many other portable devices emit blue light. Blue light has been found to be associated with eye strain, tiredness, and dry eyes. Blue light is naturally found outside from the atmosphere; however, we are now exposed to much more blue light due to the rise of technology in our current day and age. Most ophthalmologists and optometrists recommend patients to utilize blue light blockers regardless of their current visual acuity.
