Short answer: blue light glasses cost anywhere from about $5 to over $200. Non-prescription pairs from a specialist brand usually cost $30 to $80; most Sleep ZM pairs are between $30 and $60. Prescription glasses with a blue light filter cost more, because you're paying for the prescription lenses. Price is a poor guide to how much blue light a lens filters: what you want is a measured blocking figure, with the wavelength range it applies to.
Below: what you get at each price, what drives the cost, and how to get good value.
Blue Light Glasses Price Range: What to Expect
| Price | What you usually get | Good for |
|---|---|---|
| $5–$30 | Basic plastic frames; blocking figures often missing or vague | Trying the idea out, or a spare pair |
| $30–$80 | Better frames and lenses, published specs from good brands, a return policy | Most people, for daily or evening wear |
| $80–$200+ | Designer frames, premium materials, extra coatings, prescription options | Style, a specific frame, or a prescription |
Budget Pairs ($5–$30)
Cheap blue light glasses are easy to find. Some filter a reasonable amount of blue light; many don't say how much, and some filter very little. Frames and hinges tend to wear out sooner.
Mid-Range Pairs ($30–$80)
This is where most people land. You should expect a sturdier frame, a clearly stated blocking figure and a proper return policy. Our glasses sit here: for example, ReadAid reading glasses, ScreenAid yellow and SleepAid orange, with lens figures measured by Micro-Light Optics and a 30-day return guarantee.
Premium and Prescription ($80–$200+)
At the top end you're mostly paying for the frame (designer brands, titanium or acetate), extra coatings, or prescription lenses. That can be worth it if you want a particular look or need a prescription. It doesn't mean the lens filters more blue light.
What Affects the Price
- Prescription or not: prescription lenses are made to order, so they cost more. The blue light filter is often an add-on your optometrist can quote for.
- Frame material: metal, titanium and good acetate last longer than thin plastic, and cost more.
- Coatings: anti-reflective, scratch-resistant and water-repellent coatings each add cost.
- Testing: brands that pay an independent lab to measure their lenses, and publish the results, have costs that brands selling unmeasured lenses don't.
- Brand and design: some of the price is simply the name on the frame.

Do Cheap Blue Light Glasses Work?
Some do, some barely filter at all, and you often can't tell from the price or how the lens looks. A 2020 study in Clinical and Experimental Optometry measured a range of blue light filtering lenses and found that blocking in the lenses it tested ranged from about 6% to 43%. Two pairs that look the same can filter very differently.
So rather than paying more and hoping, look for:
- A blocking percentage with a wavelength range, such as "blocks 60% across 400–500nm". "Blocks blue light" on its own tells you nothing.
- Light transmission or filter category, which tells you how dark the lens is and where you can wear it.
- Who measured it: an independent lab is better than the brand's own claim.
- UV protection (UV400) and a return policy.

Are Expensive Blue Light Glasses Worth It?
Only for the frame, the coatings or a prescription. A higher price doesn't make the filter stronger, and no price buys benefits the evidence doesn't support: a 2023 Cochrane review found blue light filtering glasses probably make no difference to eye strain in the short term.
What matters more than price is choosing the right lens for when you'll wear it. Our four main lenses, measured by Micro-Light Optics:
- Clear (InvisiAid): blocks 35% across 400–500nm, 86% light transmission. For daytime screens.
- Yellow (ScreenAid): blocks 60% across 400–500nm, 79% light transmission. For daytime screens.
- Orange (SleepAid): blocks 99% across 380–550nm, 48% light transmission. For the two to three hours before bed.
- Red (SleepAidMax): blocks 99.7% across 380–580nm, 22% light transmission. For the last hour before sleep.
Orange and red lenses are not for driving.
Tips for Getting Good Value
- Decide what they're for first: daytime screens, the evening, or reading. That decides the lens, and the lens matters more than the price.
- Check the specs, not just the reviews.
- Look for a return policy of at least 30 days.
- If you wear glasses, compare a clip-on or fit-over pair with adding a filter to your prescription lenses.
- Look after them: a case and a microfiber cloth make any pair last longer. See how long do blue light glasses last?
Frequently Asked Questions
How Much Should You Pay for Blue Light Glasses?
For most people, $30 to $80 buys a well-made, non-prescription pair with published lens figures. Pay more for a designer frame or a prescription.
Are Cheap Blue Light Glasses Fake?
Not always, but many don't say how much blue light they filter, and some filter very little. Look for a measured figure rather than going by price.
How Much Does It Cost to Add Blue Light Filtering to Prescription Glasses?
It varies by optometrist and lens. Ask for a quote when you order your lenses, and ask what percentage of blue light the filter blocks.
Are Blue Light Glasses Worth It?
They're most useful in the evening, when an orange or red lens cuts most blue light before bed. For daytime screens, many people like a clear or yellow lens, but the evidence doesn't show they reduce eye strain.
Conclusion
Blue light glasses cost from about $5 to over $200, and most good non-prescription pairs are $30 to $80. Above that, you're paying for the frame, coatings or a prescription, not a stronger filter. Whatever you spend, check for a measured blocking figure and choose the lens for when you'll wear it.
