Understanding Blue Light
For most of human history, the sun has been the only source of light. It has only been recently that humans have started using artificial light. In today’s day and age of screen technology, artificial light is more inescapable than ever. Interestingly, different colors of light affect the eye differently.
Blue light is particularly interesting because the eye reacts differently to it at night than it does during the day. This type of light is most associated with screens, although it can also occur naturally. In the daylight hours, blue light may improve attention, mood, and reaction times. Exposure to blue light during the nighttime, however, may disrupt the circadian rhythm. Some people also report feeling eye strain as a result of prolonged blue light exposure.
Understanding Blueblocker Lenses
Although artificial blue light is exponentially weaker than natural blue light, the average American now spends so much time staring at screens that all the adverse side effects may start to accumulate. Research has yet to prove that blue light can directly cause eye problems, but evidence suggests it may contribute. And with the average adult spending almost 11 hours per day looking at screens, it is undoubtedly better to be safe than sorry.
Blueblocker lenses are specially coated to reflect a percentage of the blue light away from the eyes to reduce any digital eye strain and prevent significant disruptions to one’s circadian rhythm (commonly known as a person’s “biological clock,” which regulates sleep cycles). Some blueblocker lenses reflect away a higher percentage than others. They may appear either clear or yellow, though both are effective.
The Importance of Blueblocker Lenses
Blue light makes about one-third of all visible light. Although the adult human eye is typically very effective at blocking UV rays from reaching the retina at the back of the eyeball, almost all blue light will make its way through the cornea and lens to reach the retina. Critically, this exposure may increase one’s risk of macular degeneration.
Multiple studies have shown that excessive blue light exposure may damage the retina’s light-sensitive cells. Such changes can potentially lead to side effects as serious as permanent vision loss. Though more research is necessary to determine how much blue light would be needed to have such results, many patients and experts are concerned that excessive screen use may contribute. Additionally, patients who have had cataract surgery may need more blue light protection than the average person. Their natural lens has become cloudy and cannot provide as much protection.
Preventing Digital Eye Strain
As mentioned above, researchers have yet to determine how much blue light is too much. Accordingly, more research is also needed on blueblocker lenses. In any case, experts agree that reducing one’s screen time is ideal. This is often easier said than done, especially for adults who work at the computer all day.
Still, it is possible. Scripps Health recommends taking regular breaks at least once every 30 minutes. Individuals should remember to stretch, and they can set alarms to prevent themselves from forgetting. Furthermore, it is always best to sit less and stand or walk more. Paying attention to one’s posture can also help. Finally, avoid any unnecessary screen time at nighttime. If possible, ban all screens from the bedroom. The last two tips can help prevent blue light from disrupting one’s circadian rhythm.

Frequently Asked Questions
Can I get blueblocker lenses for my prescription?
Yes. We can get you the lenses and frames to meet your needs, with or without blueblocker lenses. We also offer a wide variety of fashionable frames, so you do not have to sacrifice style for safety.
Will screens look different when I wear blueblocker lenses?
No. All colors will look like they usually do. Blueblocker lenses simply reflect a portion of the blue light away from the eyes to reduce any glare or potential damage.
Do I still need blueblocker lenses if I use blue light filter apps and night mode settings?
Yes. While blue light filter apps and night mode settings can certainly ease digital eye strain, they do not filter out the source of blue light. Instead, they merely replace blue light with a reddish-orange tint. Some people even find that these apps and settings make it more difficult for them to read any text on a screen.
What are some common sources of blue light?
As mentioned earlier on this page, blue light can occur both naturally and artificially. It can most notably be emitted from the sun or digital screens (such as computers, laptops, smartphones, tablets, and TVs). However, it may also be present in fluorescent and LED lighting.
When should I wear blueblocker lenses? What happens if I wear them for too long?
You can wear blueblocker lenses whenever you want. There are no known side effects of wearing them all day. All evidence points to blueblocker lenses being as safe as any other type of optical lenses.
Can kids wear blueblocker lenses?
Yes. Anyone of any age can wear blueblocker lenses. These days, exposure to electronic devices begins earlier than ever. Kids may even start having prolonged periods of screen time starting when they are one or two years old, which may set them up for a lifetime of digital eye strain and retina damage. It is always best to establish healthy habits in children when they are still young. This is also true with blueblocker lenses.
