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 they only block 52% of overall blue light to maintain low color distortion, I found that during my longest 8-to-10 hour editing shifts, some eye fatigue still crept in by the end of the day. If you’re looking for glasses for all-day marathon sessions, you might need a pair with a stronger amber tint and higher blocking percentage.

Frequently Asked Questions
Can I wear the J+S Haka glasses over my prescription contacts?
Yes. During our testing, we found the lightweight polycarbonate frame sits comfortably on the face without interfering with contact lenses, and the non-magnified lenses won’t disrupt your prescription.
Do the J+S Haka lenses have a strong yellow tint?
No. These feature J+S’s “Low Color Distortion” lenses. While there is a very slight yellow hue to achieve the 52% blue light blocking rate, we found it barely noticeable during daily use, making them great for graphic design or watching movies.
Are the spring hinges durable?
In our weeks of daily wear, the premium spring hinges held up well, providing enough flex to accommodate different head sizes without feeling loose or fragile.
