Short answer: if you want a dedicated red lens for the last hour before bed, BLUblox (now usually sold under the Bon Charge name) makes a genuinely good one. If you live at screens from your first coffee through your late-night wind-down, you will end up buying two or three separate BLUblox pairs to cover the whole day. LITEZ puts day, focus, and night lenses inside a single frame for $99, so you change the tint instead of changing the glasses.
What BLUblox (Bon Charge) gets right
BLUblox rebranded to Bon Charge, and the eyewear line carried over. Their strength is a clear three-stage lineup. The SummerGlo yellow lens is aimed at daytime screens, the BluLite lens is a lighter clear-ish computer filter, and the Sleep+ red lens is built for night: it blocks 100% of blue and green light across the range that matters most before bed. They also carry a wide catalog of 20-plus frame styles and offer prescription and reader options, which is real and worth naming.
If your main problem is sleep, and you want one pair that you put on after dinner and take off at bedtime, a red Sleep+ pair does that job well. Bon Charge has spent years refining that lens.
Where it falls short for screen-heavy people
Here is the honest gap: with Bon Charge, each tint is its own pair of glasses. The yellow daytime lens, the clear computer lens, and the red sleep lens live in three different frames. If your day looks like screens at 9am, a long focus block in the afternoon, and more screens after dark, you are buying multiple pairs to be covered, at roughly $130 each for non-prescription frames.
That is a lot of money, and it is also a lot of friction. Three pairs means three cases, three things to lose, and a decision every time your lighting changes. Most people give up and just wear one tint all day, which means they are either too dark during work or not protected enough at night. A single fixed-tint pair cannot follow your schedule.
How LITEZ compares
LITEZ is built around one idea: screen-heavy people need a lens system, not one random pair. The 3-Lens System is $99 and puts three pop-in lenses in one frame, which works out to about $33 per lens. Swaps are tool-free and take seconds.
You get a Day (yellow) lens for daytime screens with minimal color shift, a Focus (orange) lens for long editing, coding, or gaming stretches and early evening, and a Night (red) lens that blocks up to 99% of blue light for the last hour before bed. Every lens is UV400 rated and shipping is free. Instead of owning three pairs, you own one frame and change the lens as your day changes.
Who should still pick BLUblox
Be fair: BLUblox / Bon Charge is the better buy in a few cases. If you need a prescription blue light lens, they offer Rx and readers and LITEZ does not. If you want the widest possible selection of frame shapes and colors, their catalog is deeper. And if you genuinely only care about one moment of the day, usually sleep, and never plan to swap tints, a single dedicated Sleep+ pair is a clean, focused choice. There is nothing wrong with buying exactly one tool for one job.
Frequently asked questions
Is LITEZ cheaper than BLUblox?
For full day-to-night coverage, yes by a wide margin. One LITEZ frame with all three lenses is $99. Matching that with Bon Charge means buying separate daytime, computer, and sleep pairs, and their non-prescription frames run around $130 each.
Does the LITEZ night lens block as much blue light as a red sleep lens?
The LITEZ Night lens is red and blocks up to 99% of blue light, which is the range you want in the last hour before bed. It is designed for the same evening wind-down job as a dedicated red sleep pair.
Can I get LITEZ in my prescription?
No. LITEZ is non-prescription only right now. If you need an Rx blue light lens, Bon Charge is the better fit, or you can wear LITEZ over contacts.
The bottom line BLUblox, now Bon Charge, makes a strong red sleep lens and a broad frame catalog, and if you only care about one part of your day or you need a prescription, it is a fair pick. But covering day, deep work, and night with fixed-tint pairs means buying two or three of them. If you are at screens all day and want one frame that adapts, the LITEZ 3-lens system covers the same ground for $99.
