The Eye Health Benefits of Having LED Lighting in Your Facility

March 14, 2018

Every business needs lighting, whether for an office space or warehouse, but it turns out that the lighting systems used in the majority of businesses could be harming our overall eye health. Research has shown that overexposure to “cool” or bright white fluorescent bulbs for more than 45 hours per week puts our eyes at risk for health issues such as cataracts and pterygium. Luckily, switching to LED lighting fixtures in your facility has health benefits when considering features that affect eye health such as flicker, burnout and UV emissions. Read on to find out how switching to LED will positively impact the eye health of your workers and improve your facility.


Normal lighting systems that run on AC (alternating current) display flickering at 120 Hz, or double the typical US power line frequency. This flickering is difficult for the human eye to perceive but has the potential to cause headaches, eye strain, and general discomfort according to the US Department of Energy. LED lights, on the other hand, exhibit little to no flickering because they are powered by constant DC voltage, which has the power to reduce eye strain and headaches in full-time employees.

For factory or warehouse workers, the stroboscopic effect of flickering poses a threat to those operating large machinery. When objects move or rotate rapidly, flickering light makes them look as if they are moving slower than their actual speeds. LED systems, therefore, not only reduce health risks but improve the safety conditions of your facility as well.


The typical incandescent bulb burns out in less than one year, whereas most LED lights will last up to 50,000 hours. The slower burnout rate for LEDs allows for longer color consistency across the lifetime of the fixture. Color consistency is a parameter of light quality for a lighting fixture and is important not only from an aesthetic perspective, but also significantly reduces eye strain and the risk of developing a migraine.

UV Radiation

Perhaps the biggest eye health benefit of installing LED fixtures in your facility is that they do not emit UV radiation, and therefore are safe for close-proximity exposure. Fluorescent bulbs emit UV radiation which may result in overexposure of the skin when used in desk or task lighting applications and has the potential to cause premature aging and skin cancer in addition to general eye strain and headaches.

When choosing between traditional fluorescent lighting systems and LED systems for your facility, the choice is clear—LED lighting systems have significant eye health benefits that fluorescent systems lack. Due to their lack of flickering, a much slower burnout rate and no UV emissions, the chances of your workers complaining of a headache, eye strain, or general discomfort goes down considerably. Choosing Go Beyond Lighting to handle your LED installation is not only a sound economic investment but a commitment to the well-being of your workforce.
