So, you’ve probably seen all over social media people talking about blue light glasses and have subsequently asked yourself at one point “what are blue light glasses” and “what is blue light?”. For starters, it might be helpful to understand what in fact blue light is. Blue light is all around us and is naturally found in sunlight and artificially in fluorescent light, LEDs, computers, smartphones, and tablet screens. Blue light is a colour in the visible light spectrum that can be seen by human eyes and produces high amounts of energy due to it being short wavelength.

Blue light glasses/screen protection glasses are designed with filtering materials and surface coatings on the lenses that block a portion of blue light. Most people have daily exposure to blue light due to the increased use of technologies, particularly as a result of the lockdowns over the past two years, forcing the majority of people to turn to online work. Blue light glasses are designed to provide relief from the uncomfortable side effects some people experience with staring at screens for a long period of time.

While current research suggests there is no evidence to support claims that blue light damages the eyes, it can negatively impact your sleep cycle and be a contributing factor to digital eye strain. It is recommended that the use of technological devices is reduced in the evenings and that at least 30 minutes before bed you stop looking at a screen altogether. So maybe it’s time to pick up that book you’ve so lovingly shoved under your bed or is lost under the pile of paperwork on your bedside table.

If you’ve been thinking to yourself lately that blue light glasses might be suitable for you, we do have a sample lens in our practice that you trial in-store with your laptop or phone to see if your eyes feel more comfortable looking at a screen. 

It is important to remember that while it could be blue light that is negatively impacting your eyes, we recommend booking a comprehensive eye examination with an optometrist to rule out other potential causes for screen-related visual discomfort, such as eye muscle issues, dry eyes, and vision difficulties.
