J+S Haka LCD Rectangle Review – Is It Worth It?
I spend a good chunk of my day staring at screens—between work and relaxation, my eyes are glued to a computer or a phone for at least eight hours. I noticed I was having headaches and trouble falling asleep, which I suspected was due to the prolonged exposure to blue light. Enter the J+S Haka LCD Rectangle blue light glasses. These glasses are designed to filter out the most harmful blue light, and they caught my attention immediately. After using them consistently for a few weeks, I can honestly say they’ve made a noticeable difference. The eye strain I used to experience has significantly decreased, and I feel a lot more comfortable during long work sessions. My expectations were cautiously optimistic, and I’m pleased to report that these glasses have exceeded them.
???? Quick Verdict:
If you’re someone who’s in front of screens for hours on end, the J+S Haka LCD Rectangle glasses could be exactly what you need. They effectively reduce eye fatigue and are comfortable for prolonged use. However, if you only spend minimal time on devices, these might not be necessary. They’re perfect for anyone in need of stylish, practical blue light protection.
Design & Build Quality
The first thing I noticed when unboxing the J+S Haka LCD Rectangle glasses is their sleek design. The black glossy frame has a classic rectangular shape that feels both modern and timeless. Made from polycarbonate, both the frame and lenses are lightweight, which is a huge plus for extended wear. I’ve worn them for full workdays and never felt discomfort or pinching thanks to the premium spring hinges. The glasses come in a well-crafted PU leather metal case with a microfiber cleaning cloth—nice touches that add to the overall premium feel.
Features & Performance
Focusing on the performance, the J+S Haka LCD Rectangle is engineered to block around 90% of the most harmful high-energy blue light. In my testing, I found that when working on graphic design projects or binge-watching shows, the low color distortion feature truly shines. Colors remain vibrant without the typical yellowish tint you get with some other blue light glasses. While the lenses have a slight yellow tint, it didn’t bother me or distort colors significantly. Compared to the Gunnar Vertex Onyx glasses, I’d say J+S offers comparable protection but with a more comfortable design for my face shape. However, keep in mind that these are most effective if you’re planning to use them for less than four hours a day. Because the low color distortion lenses only block 52% of overall blue light, I found that during my longest 8-to-10-hour editing shifts, my eyes still felt fatigued by late afternoon. If you need protection for all-day screen marathons, you might need a heavier amber-tinted lens that blocks a higher percentage of light.

This makes them a highly budget-friendly option compared to the Gunnar Vertex Onyx (typically $50) and premium brands like Felix Gray, which often exceed $100.

Frequently Asked Questions
Can I wear the J+S Haka glasses over my prescription contacts?
Yes. Since these feature non-prescription (plano) lenses with zero magnification, I wore them comfortably over my daily contact lenses without experiencing any dizziness or visual distortion during my testing.
Do the J+S Haka lenses have an anti-reflective coating?
Yes, during our hands-on review, we noted a multi-layer anti-reflective coating on both the front and back of the lenses. This significantly reduced screen glare from overhead office lights and nearby windows.
Are the frames adjustable for wider faces?
While the polycarbonate frames themselves aren’t heat-moldable like acetate, the built-in premium spring hinges allow the arms to flex outward. This accommodated wider face shapes on our testing team without causing pinching behind the ears.
