TIJN Blue Light Blocking Glasses, TR90 Frame

Long stretches at a computer can leave you wanting a more comfortable screen-wearing setup. These TIJN glasses pair clear, non-prescription lenses designed to help filter blue light with a lightweight TR90 frame, so you can wear them for work, reading, gaming, or everyday screen use without adding prescription correction.

They come in Square, Oval, and Cat-Eye shapes, with a retro Y2K look.

Technical details

The frame is made from TR90, described as flexible and durable, and the lenses are clear and non-Rx. The design is a medium fit intended for most adult faces. That is a useful starting point, but the listed dimensions matter more than the general fit description if glasses often feel too wide or narrow on you.

• Square: 51-17-146 mm, lens height 32 mm, frame width 140 mm
• Oval: 49-20-148 mm, lens height 34 mm, frame width 145 mm
• Cat-Eye: 53-17-146 mm, lens height 20 mm, frame width 140 mm

The product is presented as blue-light filtering eyewear, not prescription glasses. Its lens design is intended to help filter blue light from digital screens, according to the maker, the information provided does not specify a filtering percentage or establish a particular effect on eye strain or sleep. Treat it as a screen-use accessory, not a substitute for corrective lenses.

Getting the most from it

These glasses are intended for computer work, office or work-from-home setups, reading, gaming, travel, and casual daily wear. For example, you could keep a pair by your laptop and put them on for a long stretch of emails, then wear them again while gaming in the evening. The clear lenses and everyday frame styling make them less conspicuous than tinted eyewear, while the three shapes give you a choice of look.

A solid pick if you want clear, non-prescription glasses for screen-heavy routines and care about choosing a specific frame shape. If your priority is correcting vision, or you need a stated lens-filtering specification to compare products, the details here do not answer that need.

Usage tips

Choose the shape by comparing its frame width and lens height with glasses you already find comfortable. The Cat-Eye option has the shortest listed lens height, while the Oval has the widest frame, those differences can affect how the frames look and sit. The dimensions are given for each style, so avoid choosing based on the shape name alone.

Because the lenses are non-Rx, they are not described as providing vision correction. These are best considered for adding a lightweight frame and clear filtering lenses to screen time, rather than as a replacement for prescription eyewear. The product details also do not include a case or other accessories, so don’t assume one is included.

Practical doubts

Are these prescription glasses? No. The listing describes clear non-Rx lenses, so they do not provide a prescription correction.

Which frame styles are available? Square, Oval, and Cat-Eye, each with its own listed frame dimensions.

Can they be worn away from a computer? They are also described for reading, gaming, office use, travel, and casual daily wear. The lenses are clear, and the product is positioned as everyday eyewear as well as a screen-use accessory.

Buying verdict

Not the best choice if you need prescription lenses, or if your decision depends on a specific blue-light filtering rate that is not provided. For someone who wants clear non-Rx lenses, a lightweight TR90 frame, and a choice between three retro-inspired shapes, the appeal is more about convenient everyday screen eyewear than a specialized optical solution. Compare the measurements with a pair you already wear comfortably before picking a style.
