What is Blue Light and Ultraviolet Light?

Blue light is part of the visible light spectrum and is emitted by the sun and artificial light sources such as LEDs, computers, and smart phones. Some types of blue light can be beneficial and help regulate our bodies’ internal biological clocks. However, blue-violet light can have a harmful impact on the eyes, specifically the retina. It is also a risk factor for the onset of age-related macular degeneration, a deterioration of the part of the retina responsible for sharp, central vision.

Ultraviolet light not only affects the skin by increasing the risk of skin cancer, it can also be dangerous for the eyes. Excessive exposure to UV light without proper protection can lead to cataracts. It can also cause a sunburn on the cornea of the eye (known as photokeratitis), which can lead to temporary blindness.

How It Works

Since some forms of blue light are necessary, these specialty lenses selectively block only the harmful types of blue light. Colombo Eye Care offers various No-Glare lenses that also offer comprehensive UV protection.

Do You Need Protection against Blue and UV Lights?

Blue light is emitted by a plethora of electronic devices including cell phones, tablets, and laptop computers. A recent study found that Americans devote more than 10 hours a day to screen time, meaning protection against blue light is important for anyone using a digital device on a regular basis. Another source of blue light is energy efficient technology in the form of fluorescent light bulbs and LED lights. Most offices and stores use fluorescent light bulbs, thus putting your eyes at risk if unprotected.

It’s important to protect your eyes against UV exposure both indoors and out. Our eyes are exposed to UV radiation 365 days a year, even on cloudy days. In fact, up to 40% of UV exposure occurs when we aren’t in full sunlight.

Since most people are at risk for overexposure to both blue light and UV light on a daily basis, it’s important to talk to one of our doctors about how these lenses can protect your eyes from harmful blue light and ultraviolet light.
