About this site

Blue Block Review helps people choose blue light glasses without overpaying for the part that isn’t proven. We read the published research, we are explicit about what we have not tested, and we tell you when the right answer is to skip the purchase.

Last reviewed August 2026. We update a page when the underlying evidence changes, not on a schedule.

Who writes this

A small independent editorial team. We are not optometrists, ophthalmologists or vision scientists, and we do not present ourselves as any of those. What we do is read primary sources carefully, check what manufacturers actually commit to in writing, and write up the result in plain language.

You will not find invented staff biographies or fabricated credentials here. Those are common in this corner of the web and they are a reason to distrust a site, not to trust it. If a claim on this site carries weight, it is because of the source attached to it, not because of who we say we are.

What we actually do

  • Read the primary research. Systematic reviews first, then individual trials, with attention to sample size, blinding and who funded the work. Every finding on the site links to its source.
  • Separate claims from measurements. A manufacturer's filtering percentage is labelled as their claim. We do not restate it as fact, and we explain why most such numbers are unverifiable.
  • Say when the evidence is thin. Some questions here are genuinely unresolved. We label them that way instead of picking a side for the sake of a cleaner conclusion.
  • Make a call. Every pick names who should buy it and who should skip it. A roundup that recommends everything has recommended nothing.
  • Say when not to buy. For some readers the right answer is an eye exam, not a purchase. We say so, and an affiliate site that never does is not doing its job.

The longer version is on the how we work page.

How we make money, and why it matters less than you might think

We earn affiliate commissions on some outbound retailer links. If you click one and buy something, we receive a small percentage of the sale; the price you pay is unchanged.

The usual defence offered by affiliate sites is that they earn the same rate regardless of which product you buy, so they have no incentive to steer you. That is only half true — commission is typically a percentage, so a more expensive product does pay more. We would rather state the conflict accurately than offer a reassurance that does not survive inspection.

The real check on us is the writing itself. We recommend spending on the frame rather than the filter, which points readers at the cheaper half of the category. We publish the evidence that undercuts the industry's main selling point on the same pages that carry the affiliate links. If commissions were shaping the content, both of those would be the first things to go.

What we will not do

  • Claim hands-on testing we have not done.
  • Publish star ratings or review counts we cannot verify, or embed them in structured data to win search results.
  • Repeat a filtering percentage as though it were a measurement.
  • Print hard prices that will be wrong within weeks, or "was" prices we cannot substantiate.
  • Use countdown timers, fake scarcity, inflated "was" pricing, or invented urgency of any kind.
  • Recommend a product we would not suggest to a friend spending their own money.
  • Give medical advice, or imply that we are qualified to.

Corrections

If something here is wrong, we want to know, and we will correct it in public rather than quietly editing the page. Email corrections@blueblockreview.com. Corrections that change a conclusion get noted on the page itself.
