Blue Light Filtering Glasses in Brooklyn: Do You Really Need Them?
If you're spending more time on screens than ever before, you've probably heard about blue light filtering glasses. Here's what you need to know: yes, blue light is real, and yes, excessive screen time can cause eye strain and sleep disruption. But whether blue light glasses are right for you depends on your specific situation, and Dr. Shlivko can help you figure that out.
Key Takeaways
- Blue light from screens is real and can contribute to digital eye strain and sleep disruption
- Blue light filtering glasses reduce glare and may improve comfort during extended screen use
- They're particularly helpful for people who work on computers 6+ hours daily or spend evenings on phones and tablets
- Not everyone needs them—sometimes better habits or standard anti-reflective coating does the job
- Dr. Shlivko at Nostrand Optical can evaluate your screen habits and recommend the right solution for you
What Is Blue Light, and Where Does It Come From?
Blue light is a high-energy wavelength of visible light that's everywhere. The sun produces it. Your phone produces it. Your laptop produces it. Your TV produces it. It's not inherently harmful—your eyes and body are designed to deal with blue light during the day. In fact, blue light helps regulate your circadian rhythm and keeps you alert.
The problem isn't blue light itself. The problem is how much of it you're getting and when you're getting it.
If you're working on a computer for eight hours straight, then scrolling on your phone before bed, you're getting a lot of blue light exposure—especially during evening hours when your body is supposed to wind down. That's when blue light filtering becomes relevant.
Most people in Crown Heights and Brooklyn are working more from home than ever before. Screen time has increased dramatically. That's why we're seeing more patients at Nostrand Optical mentioning eye fatigue, blurry vision at the end of the day, and trouble sleeping after evening screen use.
Digital Eye Strain: The Real Problem Behind Blue Light Concerns
Here's something important to understand: blue light isn't the only culprit in digital eye strain. In fact, it's not even the biggest one.
When you stare at a screen, you blink less often. You focus intently on something close to your face for extended periods. You may have poor posture or inadequate lighting. All of these things cause eye strain, regardless of blue light.
The symptoms of digital eye strain (sometimes called computer vision syndrome) include:
- Blurry vision, especially at the end of the workday
- Dry, scratchy eyes
- Headaches or tension around the temples
- Neck and shoulder pain from posture
- Difficulty refocusing when you look away from the screen
If you're experiencing these symptoms, a pair of blue light filtering glasses might help, but they're only part of the solution. Dr. Shlivko will evaluate your full situation—your work setup, your habits, your prescription, and whether you have dry eye disease—before recommending what you actually need.
How Blue Light Filtering Glasses Work
Blue light filtering glasses use a special coating or lens material designed to block or absorb some of the blue light wavelengths coming from screens. The coating reflects a portion of blue light away from your eyes, reducing the amount that reaches your retina.
There are a few different approaches:
Blue light coatings on regular lenses: A thin coating is applied to your prescription lenses (or non-prescription lenses). It's subtle—you might see a very slight yellow or amber tint when you look at the lenses, but it's barely noticeable when you're wearing them.
Specialized blue light blocking lenses: Some lens materials are formulated to absorb blue light more effectively than standard coatings. These are often slightly tinted.
Computer glasses with blue light filtering: These are non-prescription glasses designed specifically for screen use. They have the blue light coating built in.
The key thing to know: blue light filtering glasses don't eliminate all blue light. They reduce it. The reduction is modest—typically filtering 50-90% of blue light depending on the coating quality—but for many people, that's enough to make a noticeable difference in comfort.
Who Actually Benefits From Blue Light Filtering Glasses?
Not everyone needs them, and Dr. Shlivko won't recommend them if they're not right for your situation.
You're a good candidate for blue light filtering glasses if:
- You work on a computer for 6 or more hours daily
- You use screens in the evening and have trouble sleeping
- You're experiencing digital eye strain symptoms (blurry vision, dry eyes, headaches)
- You've already tried other solutions (better posture, breaks, eye drops) and still struggle
- Your job requires focused screen work with little variation
You might not need blue light filtering glasses if:
- Your screen time is limited and casual
- You don't experience eye strain or sleep issues
- Your symptoms improve with better habits (more frequent breaks, better lighting, reduced evening screen use)
- You have significant dry eye disease that needs treatment first
A real example: Marcus, a 38-year-old who works as a graphic designer in Crown Heights, came to Nostrand Optical complaining of afternoon eye fatigue and trouble sleeping even on nights when he finished work early. He'd heard about blue light glasses and wanted to try them. Dr. Shlivko evaluated him and found two things: Marcus has mild dry eye (which makes digital eye strain worse), and his evening screen habits were reinforcing sleep problems. Dr. Shlivko recommended blue light filtering glasses, but also prescribed dry eye treatment and discussed wind-down routines. After a month, Marcus reported significant improvement—not just from the glasses, but from addressing all the factors contributing to his discomfort.
Blue Light Glasses vs. Other Solutions
Before investing in blue light filtering glasses, it's worth considering what else might help.
Anti-reflective coatings: A standard anti-reflective (AR) coating reduces glare from all light sources, including blue light. It won't filter blue light specifically, but it does reduce overall eye strain by minimizing reflections on your lens surface. This is a good baseline for anyone who spends time on screens.
Dry eye treatment: If your screen-related discomfort is actually dry eye—which is extremely common—dry eye treatment will make more difference than blue light glasses. Treating the underlying dryness addresses the root cause.
Our dry eye treatment in Brooklyn covers evaluation and management strategies that work fast.
Better screen habits: 20-20-20 rule: every 20 minutes, look at something 20 feet away for 20 seconds. This gives your eyes a break and reduces fatigue significantly. Take this seriously before spending money on special glasses.
Better lighting: Poor lighting makes screen-related eye strain worse. Make sure your workspace is well-lit without glare on your screen. That alone can reduce symptoms.
Blue light filtering glasses are often most effective when combined with these other strategies, not as a standalone solution. That's why Dr. Shlivko takes a comprehensive approach—he's not just selling you glasses, he's identifying what's actually causing your symptoms.
What the Research Actually Says About Blue Light Glasses
You'll see claims everywhere about blue light filtering glasses. Some are overstated. Here's what the science actually shows:
Studies from the American Academy of Ophthalmology and the American Optometric Association confirm that blue light does reach your eyes from screens and can contribute to circadian rhythm disruption, especially in the evening. That part is real.
Studies on whether blue light filtering glasses specifically reduce eye strain show mixed results. Some studies show modest improvement in eye comfort and sleep quality. Other studies show little difference compared to placebo. The variation depends on the study design, the coating quality, and the population studied.
What's clear is this: if you're experiencing digital eye strain, blue light glasses can help—but they're not a magic fix. The improvement is often modest, and it's most noticeable when combined with other strategies like better breaks, reduced evening screen time, and treatment of underlying dry eye.
If you're interested in trying them, there's no harm in it. If they help you, great. If they don't, you haven't lost much except the cost of the coating.
Should You Get Blue Light Filtering Glasses? Here's How to Decide
Start by asking yourself these questions:
- Do I spend more than 6 hours daily on screens?
- Am I experiencing eye strain symptoms or sleep problems?
- Have I tried other solutions (breaks, better lighting, posture adjustments)?
- Do I use screens in the evening, close to bedtime?
If you answered yes to most of these, blue light filtering glasses are worth considering. If you answered no, you probably don't need them.
The next step is getting a professional evaluation. Dr. Shlivko will ask about your symptoms, your work setup, and your habits. He'll check your vision and assess whether you have dry eye or other issues that might be contributing to discomfort. Then he can give you a personalized recommendation.
Sometimes that recommendation is blue light filtering glasses. Sometimes it's dry eye treatment. Sometimes it's better screen habits. Often it's a combination.
If you're dealing with screen-related eye discomfort, schedule an eye exam with Dr. Shlivko at Nostrand Optical. We accept Medicaid and Medicare, and same-day glasses are available for most prescriptions. You don't need to guess whether you need blue light filtering—let's figure it out together.
Blue Light Glasses and Sleep: What You Need to Know
One of the most common reasons people get blue light filtering glasses is to improve sleep. The logic is sound: blue light suppresses melatonin production, which is why looking at your phone before bed can keep you awake. If you filter out blue light in the evening, you might sleep better.
This is where the research gets interesting. Studies show that blocking blue light in the evening does help some people fall asleep more easily. But the effect is modest—typically 30 minutes to an hour earlier sleep onset, not a dramatic difference.
More important than blue light filtering, frankly, is simply putting the screen down an hour before bed. That gives your brain time to wind down and your melatonin levels time to rise naturally. No special glasses required.
But if you're someone who needs to work or scroll in the evening, blue light filtering glasses are a reasonable compromise. They're not a substitute for good sleep hygiene, but they can help.
One patient story: Jennifer, a 52-year-old from Crown Heights, works evening shifts at a hospital and was struggling with sleep when she got home. She'd scroll on her phone to unwind for 30-45 minutes before attempting sleep, then spend an hour tossing and turning. She came to Nostrand Optical asking about blue light glasses. Dr. Shlivko recommended the glasses but also suggested she try putting the phone down 30 minutes earlier. She combined both strategies—wore the blue light glasses during her post-shift phone time and stopped scrolling 30 minutes before bed. Within two weeks, her sleep improved noticeably. The glasses helped, but the behavior change was the bigger factor.
Prescription Blue Light Filtering Glasses vs. Over-the-Counter
You can buy blue light filtering glasses without a prescription at drugstores, online, and at big-box retailers. You can also get them with your prescription from an optometrist. Which is better?
Over-the-counter blue light glasses are convenient and cheap, but they have downsides:
- They're generic—not optimized for your specific vision needs
- The blue light coating quality varies wildly
- If you need a prescription, you're getting the wrong power and the blue light filtering
Prescription blue light filtering glasses from Dr. Shlivko are tailored to your eyes. If you need vision correction, the glasses will correct your vision and filter blue light. If you don't need correction, we can make non-prescription computer glasses with high-quality blue light coating.
For most people, prescription glasses with blue light filtering make more sense than over-the-counter options. You're getting the right prescription, the right coating, and professional fitting all in one.

Computer Glasses vs. Regular Glasses with Blue Light Coating
There's a difference between generic "computer glasses" and your regular prescription glasses with blue light filtering added.
Computer glasses are optimized for the specific distance and angle of your screen. They may have a slightly different power than your regular glasses to reduce accommodation strain (the effort your eyes make to focus close-up). They're designed specifically for screen work.
Regular prescription glasses with blue light coating correct your general vision need and add blue light filtering on top. They're good for all-purpose use, not optimized for screens specifically.
If you spend most of your workday at a computer, dedicated computer glasses might be worth the investment. If you need glasses for varied distances and activities, regular glasses with blue light coating are probably sufficient.
Dr. Shlivko can discuss which approach makes sense for your lifestyle and work setup. Sometimes patients get both—computer glasses for work and regular glasses for everything else.
Potential Downsides of Blue Light Filtering Glasses
Blue light filtering glasses are safe and low-risk, but there are a few things to be aware of:
Slight color distortion: The blue light coating can give your lenses a subtle yellow or amber tint. For most people, this is barely noticeable. For others, it's annoying. If you're sensitive to color, you might want to try them on before committing.
Not a complete solution: As discussed, blue light glasses work best as part of a broader strategy. If you're expecting them to eliminate all eye strain on their own, you'll be disappointed.
Cost: A blue light coating adds to the cost of your glasses. It's usually $20-50 more than standard lenses, but it varies. We accept Medicaid and Medicare, and same-day glasses are available at Nostrand Optical, so cost shouldn't be a barrier to getting what you need.
Reduced benefit without other changes: If you don't change your screen habits—still staring at the screen for 8 hours straight without breaks, still scrolling before bed, still in poor lighting—blue light glasses won't make a huge difference.
The Bottom Line: Should You Get Blue Light Filtering Glasses?
Here's the honest answer: blue light filtering glasses can help reduce eye strain and improve sleep for many people, especially those who work on screens most of the day. They're not a miracle solution, but they're a reasonable tool when combined with better habits and proper eye health management.
You don't need them if you're not experiencing symptoms. You don't need them if you're only on screens a few hours daily and feel fine. But if you're working on a computer for 6+ hours daily, experiencing eye strain or sleep issues, and you've already tried other solutions, they're worth trying.
The key is getting personalized advice from someone who knows your eyes and your situation. Dr. Shlivko will evaluate whether blue light filtering glasses are right for you or whether other solutions would work better. That evaluation is part of a comprehensive eye exam.
If you're dealing with screen-related discomfort, digital eye strain, or sleep problems related to evening screen use, it's time to get your eyes checked. Dr. Shlivko at Nostrand Optical can assess your situation and recommend the right solution—whether that's blue light filtering glasses, dry eye treatment, better screen habits, or a combination of approaches.

FAQ: Blue Light Filtering Glasses in Brooklyn
Do blue light filtering glasses really work?
They reduce blue light exposure and can improve comfort for people who spend significant time on screens. The benefit is modest but noticeable for many people, especially when combined with other strategies like better breaks and reduced evening screen time.
Will blue light filtering glasses help me sleep better?
They can help, especially if you use screens in the evening. But putting your phone down an hour before bed is more effective. Blue light glasses work best when combined with better sleep habits.
Are blue light filtering glasses expensive?
A blue light coating typically adds $20-50 to the cost of your glasses. At Nostrand Optical, we accept Medicaid and Medicare, so cost shouldn't prevent you from getting what you need.
Do I need prescription blue light glasses or can I buy them over the counter?
If you need vision correction, prescription glasses with blue light filtering are much better. Over-the-counter options don't account for your prescription and have variable coating quality. If you don't need vision correction, over-the-counter computer glasses are an option, but professional-grade options are usually better.
Should I wear blue light filtering glasses all day or just when I'm on screens?
Most people wear them when they're working on screens or using devices in the evening. If you spend most of your day on screens, you might wear them most of the day. Dr. Shlivko can recommend what makes sense for your routine.
Can blue light filtering glasses cause any side effects?
They're very safe. The main potential issue is slight color distortion from the coating, which some people find annoying. Beyond that, no serious side effects.
Should my kids get blue light filtering glasses?
Kids are spending more time on screens than ever, so it's a reasonable question. The research on blue light in children is limited, but general screen time reduction and 20-20-20 breaks are more important than special glasses. Dr. Shlivko can advise based on your child's specific situation during a pediatric eye exam.
Are blue light filtering glasses better than regular anti-reflective coatings?
They serve different purposes. Blue light filtering specifically targets blue wavelengths. Anti-reflective coating reduces all glare. For screen use, blue light filtering is more targeted, but anti-reflective coating also helps. Sometimes both are useful together.
