Risks Of Blue Light
The Schepens Eye Institute demonstrated that a low density of macular pigment may represent a risk factor for AMD by permitting greater blue light damage.
Recent research indicates a strong link between exposure to blue light and incidences of Cataracts
Blue light causes less contrast to be visible to the human eye, this causes more strain on our eyes. This is particularly common with people who work most of the day on the computer.

Blue Light Protection
Nowadays, most of us spend many hours a day sitting in front of a modern TV, computer screen, tablet, or smartphone. The light from the screen of these digital devices has adverse effects on our retina, and the long-term effects are still unknown. If you spend hours a day in front of a screen, sooner or later, you are likely to feel discomfort in your eyes including soreness, fatigue, and blurriness.
At Pike Peak Eye Care, we provide our patients with sophisticated blue light blocking lenses that can shield your eyes from direct exposure to blue light.
Sunlight consists of various colors of light. This includes orange, yellow, red, green, indigo, blue, and violet light. When combined, they form white light. Each of these colors corresponds to a different wavelength of light. The shorter the wavelength, the higher the energy. Blue and violet light have the shortest wavelengths on the visible light spectrum, sitting just below the ultra-violet wavelengths in terms of energy output.
This is what we expose our eyes to whenever we stare at the screen of our digital devices. Prolonged exposure strains your eyes, messes with your sleep cycle, and likely causes serious long-term damage.
Sunlight is the largest source of blue light. Other sources include:
- LED light
- Fluorescent light
- CFL (Compact Fluorescent Light) bulbs
- Flat screen LED televisions
- Computer monitors, tablet screens, and smartphones
No. Some blue light exposure is important as it helps regulate our sleep and helps stave off depression and Seasonal Affective Disorder (SAD). The best way to get helpful levels of blue light is to go outside during the day and spend some time out of doors.
The problem with blue light from digital devices is that it is a lot of focused and continuous blue light in a way we don't experience in nature. It is this kind of exposure which is causing problems and worrying optometrists.
Is my Digital Device Screen Dangerous to my Eyes?
Our eyes absorb light. Light on high-energy end of the visible spectrum is typically called blue light. This light goes through the cornea and lens, directly into the retina. This can cause long-term damage and possibly cause your eyes to age prematurely. Some of the dangers of blue light on the eyes include:
Blue light from digital devices and computer screens can reduce contrast. This causes digital eye strain. Dry eyes, fatigue, bad lighting, and the way you sit in front of your computer can also contribute to eye strain. Typically, you will feel discomfort, soreness, and perhaps blurred vision. At times, you may find it difficult to focus.
Recent studies have shown that overexposure of the eyes to blue light can damage the retinal cells. This may lead to vision issues such as age-related macular degeneration which eventually leads to permanent loss of vision.
Exposure to excess blue light at night through indoor lighting, digital devices, or computer screens is proved to disrupt the circadian rhythms that regulate our sleep patterns. It tricks your internal clock into thinking that it is the middle of the day. This causes difficulty in falling asleep, insomnia, and daytime fatigue.
Research shows that overexposure to blue light reduces melatonin production. Melatonin is a hormone that affects our bodies circadian rhythms, which regulate sleep among other processes. Recent experimental evidence at Harvard University also indicates a correlation between lower levels of melatonin and the associated frequency of cancer.
Blue Light Blocking Lenses at Pikes Peak Eye Care in Colorado Springs
To help prevent long-term damage to your eyes, our Colorado Springs eye clinic provides state-of-the-art blue light blocking lenses and lens coatings for both children and adults. This will help protect your eyes from exposure to blue light and allow you to use your digital devices more comfortably. Our blue light blocking lenses include Essilor’s Eyezen and Prevencia, as well as BluTech, considered the two best options on the market.
Eyezen is a premier lens that we are proud to offer at Pikes Peak Eye Care. Eyezen enhanced single vision lenses are designed for the way you see the world, reducing strain from viewing digital devices. These computer glasses also filter blue-violet light, helping to keep your eyes protected and comfortable, even on your most digital days.
Crizal Prevencia lenses from Essilor are the result of research conducted by the Vision Institute in Paris, which identified the exact spectra of light which should be blocked. Prevencia was the first blue light protective lens to offer selective filtering. The harmful, higher energy blue light (blue-violet) is blocked while the beneficial lower blue (blue-turquoise) is allowed to pass through. This allows you to continue to see in true color along with the benefits of natural blue light, while still protecting your eyes from strain and damage.
BluTech pioneered the first fully-protective lenses for Blue Light. Originally marketed as computer lenses, they originally blocked all blue light, making things appear yellowish. The technology has since improved to the point that their near-clear lenses block the vast majority of Blue Light while preserving true colors. BluTech Lenses offer some of the best Blue Light protection on the market.
