Blue Light and Protective Lenses

Is Blue Light?

Blue light is quite high in intensity along the visible light spectrum. It is just below the UV radiation, which we know can be incredibly harmful. Being so close to UV on the spectrum, many experts believe that blue light can almost have similar harmful effects on the human eye. It may not be as intense as UV itself but the long-term exposure is questionable.

Computer Use Syndrome

43% of adults work in a job that requires prolonged use of a computer or tablet. Excessive exposure in the long term could increase the risk of losing central vision, which is also known as macular degeneration. Due to the high flicker rate of blue light wavelengths, they create a glare that deteriorates visual contrast, sharpness, and clarity. This is also the reason why most people.

commonly feel eye strain after using these devices for long hours. Eye experts advise limiting the use of blue-light emitting devices, but in today’s society, they can be hard to avoid entirely. For this reason, we recommend using blue-light protective eyewear.

Blue Light Protective Lenses

In natural occurrences, blue light is everywhere. Fortunately, blue light protective lenses can help to better guard your vision against the dangers of everyday exposure that can be harmful to you. We encourage our patients to consider adding a blue light protective coating to their lenses to help filter some of the blue light that is emitted from electronic devices. In fact, we even recommend these lenses for those who don’t need glasses to see clearly. In those cases, we would simply apply a blue light coating to a lens without a prescription, and these lenses would be worn anytime you would use an electronic device or when working on your computer. This is especially important for children who may be using devices, as this added protection can help prevent vision damage at an early age.

Other Considerations

In addition to adding an extra layer of protection to your optical lenses, you can also alter the settings on your devices to limit your exposure to blue light. Most modern cell phones have the option to apply a blue light filter to shift the emissions to a warmer red light at night. Dimming your screen brightness can also help prevent eye strain. This is especially important if you are viewing your device at night or in a dark room.
