Americans are spending more time than ever in front of electronic devices. It’s estimated that the average person spends over 10 hours on video games, smartphones, computers, and tablets every day. Unfortunately, these devices give off harmful blue light that damages your eyes, reduces restful sleep by suppressing melatonin secretion, and causes other health problems.
Blue light glasses offer the necessary protection against this harmful light source, but you may have questions. Here’s a closer look at the most frequently asked questions about blue light protection glasses.
What is Blue Light?
Blue light is a type of light with a shorter wavelength and higher level of energy. Blue light is not inherently bad. In fact, the largest producer of blue light is the sun, and your body needs it to function. For example, blue light helps your body regulate its sleep cycle so that you’re more tired in the evening.
However, too much blue light is harmful to your body and eyes. If you are exposed to too much blue light you may experience symptoms of eye fatigue or strain, disrupted sleep, headaches, and insomnia. Additionally, children are more likely to be negatively impacted by the harmful effects of blue light overexposure since their eyes are still developing.
What Are Blue Light Blocking Glasses For?
Blue light protection glasses absorb a portion of the blue light your eyes are exposed to. Early research has shown that blue light glasses can be helpful if you’re having trouble sleeping, experiencing other blue light overexposure symptoms, or if you spend a lot of time using digital devices.
Can You Wear Blue Light Protection Glasses All Day?
You can wear blue light blocking glasses all day to protect yourself from blue light overexposure. Wearing blue light glasses throughout the day can be especially helpful to those who spend more time in front of digital screens.
For example, if you have an office job where you spend most of your time in front of a screen, you’ll reap more benefits than someone who doesn’t.
However, blue light glasses will also block out much of the sun’s natural blue light. This means that you may experience some adverse effects on your alertness and wakefulness earlier in the day.
Do Blue Light Protection Glasses Help You Get More Sleep?
Since blue light protection glasses shield your eyes from blue light emitted by digital devices, these glasses can be especially helpful during evening hours. With blue light glasses, you’ll experience less sleep interruption and blue light overexposure symptoms like insomnia.
Do Blue Light Glasses Help With Eye Strain?
Overexposure to blue light can be harmful to your eyes, leading to eye fatigue and eye strain. Because of these common symptoms, many consumers have reported that using their blue light glasses has resulted in less eye strain and that their eyes feel less irritated and tired by the end of the day.
Do Blue Light Glasses Help With Headaches?
Because headaches are a common symptom of eye strain, blue light protection glasses can reduce the severity and frequency of headaches that you experience due to looking at digital screens for a lengthy period.
Will Blue Light Blocking Glasses Damage Your Eyes?
Blue light glasses do not cause damage to your eyes, nor do they change your sensitivity to blue light. Instead, these glasses protect your eyes from becoming damaged by overexposure to blue light.
Who Benefits Most From Blue Light Protection Glasses?
Blue light glasses are beneficial to anyone who uses digital devices that emit blue light, including smartphones, computers, tablets, video games, and other electronics. Since children’s eyes are still developing, kids benefit even more from blue light blocking glasses.
Additionally, adults who have desk jobs or other careers that require significant digital device usage should consider blue light glasses.
Can Blue Light Glasses Be Fit to a Prescription?
Blue light protection glasses can be obtained with or without a prescription. You can fit your lens prescription with blue glass filtering lenses if you already have prescription glasses. You will need your prescription details when choosing a pair of blue light glasses online.
The Bottom Line
In today’s society, it is nearly impossible to avoid using digital devices. Digital devices are an endless source of entertainment and are commonly necessary for professional and personal endeavors.
However, the rise in screen time among Americans is a cause for concern. Overexposure to blue light can cause an array of symptoms including sleep disturbance, insomnia, eye strain, and headaches.
Blue light glasses provide significant protection against harmful blue light rays cast from digital devices. These glasses don’t require a prescription but can be paired with one if necessary. Additionally, these glasses can be used all day for around-the-clock protection.
