Screens are a big part of our daily lives, and with them comes the concern about blue light exposure. While blue light isn’t inherently harmful, some people worry it might contribute to discomfort during long hours of screen use.
Blue light prescription glasses are designed to filter out a portion of this light, aiming to reduce glare and improve visual comfort. While they won’t directly prevent eye strain, they can be a useful option for enhancing your overall screen-viewing experience and supporting better sleep.
What Is Digital Eye Strain?
Digital eye strain, also known as computer vision syndrome, is a group of eye problems caused by prolonged exposure to digital screens. Symptoms can include:
- Headaches
- Blurred vision
- Dry eyes
- Neck and shoulder pain
These issues arise because our eyes work harder when we look at screens, especially if we don’t take breaks. Our eyes also tend to blink less when we’re staring at screens, which can eventually lead to dryness.
Another factor contributing to digital eye strain is screen glare. Bright screens and improper lighting can make focusing difficult, causing our eyes to strain even more. Over time, this can result in discomfort and fatigue.
What Is Blue Light?
Blue light is a type of high energy visible light with a short wavelength. It’s naturally emitted by the sun and is also present in fluorescent and LED lighting, including the screens of digital devices.
Unlike other wavelengths of light, blue light penetrates deep into the eye, reaching the retina. Excessive exposure to blue light may contribute to eye strain and discomfort.
While blue light exposure during the day can be beneficial, helping improve alertness and mood, too much of it, especially at night, can be harmful, especially for our sleeping patterns.
How Blue Light Affects Your Eyes & Health
Exposure to blue light can lead to certain eye and health issues. In particular, it can disrupt sleep patterns by interfering with melatonin production.
This disruption can lead to difficulties falling asleep and staying asleep, affecting overall sleep quality.
What Are Blue Light Prescription Glasses?
Blue light prescription glasses are eyewear designed to filter out blue light from digital screens. These glasses typically come with lenses that have a special coating to block or absorb blue light.
These glasses are available in both prescription and non-prescription options.
Prescription Blue Light Glasses vs. Non-Prescription: Which Is Right for You?
Choosing between prescription and non-prescription blue light glasses depends on your vision needs. If you have refractive errors, such as nearsightedness or farsightedness, prescription blue light glasses can correct your vision while also filtering blue light.
These glasses provide dual benefits, making them a practical choice for those who need vision correction.
Non-prescription blue light glasses are suitable for people with no vision issues who want to reduce blue light exposure. These glasses can be worn over contact lenses or by people who don’t need vision correction.
They provide a cost-effective solution for those looking to improve eye comfort and reduce screen-related discomfort.
Ultimately, though, the right choice depends on your needs and preferences. Consider your vision requirements, budget, and lifestyle when deciding which type of blue light glasses to choose.
Tips for Choosing the Right Blue Light Prescription Lenses
When selecting blue light prescription lenses, there are some things to consider:
- First, seek advice from your eye doctor to determine your vision needs. They can help you choose lenses that provide the right amount of blue light protection and cater to your vision correction requirements.
- Next, consider the lens material and coating options. Some lenses offer additional features, such as anti-reflective coatings, which can further reduce glare and enhance visual clarity. These coatings can be particularly helpful for those who spend long hours in front of screens.
- Lastly, consider your budget and lifestyle when choosing blue light prescription lenses. Prices can vary depending on the lens features and brand. Look for a solution that fits your needs without compromising on quality.
Tips to Prevent Eye Strain
Even if blue light glasses aren’t a cure for eye strain, there are other effective ways to keep your eyes feeling fresh and comfortable:
Follow the 20-20-20 Rule
Take a break every 20 minutes, focus on something 20 feet away, and do this for at least 20 seconds. It’s a simple habit that reduces eye fatigue.
Adjust Your Screen Settings
- Brightness: Match the screen’s brightness to the surrounding light.
- Text Size: Increase font size to avoid squinting.
- Color Temperature: Use warmer tones to reduce glare, especially at night.
Keep Your Screen at a Comfortable Distance
Position your screen about 20–24 inches away from your eyes and slightly below eye level to reduce strain.
Blink Often
Staring at screens can reduce blinking, leading to dry eyes. Make a conscious effort to blink more to keep your eyes moist.
Schedule Regular Eye Exams
Routine checkups can detect early signs of eye strain or other vision issues, helping you stay proactive about eye health.
Are Blue Light Glasses Worth It?
Blue light glasses can be a valuable tool for those who want to reduce their blue light exposure. However, remember that blue light glasses are just one piece of the puzzle.
Maintaining good eye health involves a combination of practices, such as taking regular breaks from screens, maintaining proper lighting, and practicing good eye habits.If you’re considering blue light glasses, book an appointment with Total Vision Hercules for guidance.
