90-Day Test: Eyeglass Frame Size Chart for Mozaer Blue Light Glasses

Don't buy before you read this.

For 90 days, I used the eyeglass frame size chart from Official Mozaer to find the right fit for their Oversized Blue Light Blocking Glasses. Here's a day-by-day look at what really happened.

• Frame sizing matters more for comfort than you'd expect
• Oversized doesn't mean one-size-fits-all
• Blue light blocking works, but how well the glasses fit determines if you'll actually wear them

Day 1: First Impressions

The box arrived with the glasses and a small card showing basic measurements. There was no detailed eyeglass frame size chart included. I measured the frames myself: 145mm temple length, 54mm lens width, 18mm bridge width.

First try-on: They felt loose. The "oversized" label was accurate. My head measures about 56cm around. These frames are meant for medium to large faces.

Verdict: Measure your face before buying. Don't guess.

Week 1: Getting Used to Them

I wore them 4–6 hours daily at my computer. The loose fit bothered me at first; they slid down when I looked at my phone.

I checked standard eyeglass frame size chart sizes online:

• Small: 125–135mm temple, 48–52mm lens
• Medium: 135–145mm temple, 52–56mm lens
• Large: 145–150mm temple, 56–60mm lens

These Mozaer frames sit right on the medium-large border. If you have a narrow face (under 13cm width), skip these.

By day 5, I adjusted the nose pads slightly, which improved the fit—but it still wasn't perfect.

Verdict: Oversized frames need a face width of at least 13–15cm.

Month 1: Daily Use

Week 3 brought a discovery: the blue light blocking actually reduced my eye strain. I normally get headaches after 8-hour screen days, but with these glasses, headaches dropped by about 60%.

But the fit issue lingered. I compared them to my old reading glasses (140mm temple, 52mm lens), which stayed put much better. The extra 2mm lens width on the Mozaer frames made them heavier on my nose.

I started using them only at my desk, not while walking around—movement made them shift.

The vintage style looked good, and three coworkers asked where I got them. The anti-blue coating has a slight yellow tint visible under bright light; it's not obvious to others, but I noticed it.

Verdict: Great for stationary computer work. Not ideal for moving around.

Month 3: Long-Term Verdict

After 90 days, the frames held up well—no loose screws, no scratches on the lenses, and the coating stayed intact.

I learned to match the eyeglass frame size chart to my actual measurements:

• My face width: 14cm (medium-large)
• My temple-to-temple: 13.5cm
• My nose bridge: 17mm

The 18mm bridge on these glasses was slightly wide for me, which explains the sliding. If your bridge measures 18–20mm, these will fit better.

The presbyopia feature worked as expected. I tested them for reading small text; they were clear at 30–40cm distance—good for people over 40 who need reading help.

Price-quality tradeoff: These cost less than premium brands. You get basic blue light blocking and decent build quality, but not a custom fit or premium materials. A fair trade for the price.

Verdict: Solid budget option if your measurements match. Check real buyer photos before ordering.

Would I Buy Again?

No—but not because of quality.

The eyeglass frame size chart issue is the dealbreaker. I need frames with a 16–17mm bridge and 140mm temples, and these are too large for my face shape.

If your measurements match (14–15cm face width, 18mm+ bridge, 145mm+ temples), then yes, buy them. The blue light blocking works, build quality is good for the price, and the style looks sharp.

My advice: Research → Measure your face → Compare to frame specs → Check reviews that mention face size → Buy.

Don't assume "oversized" means comfortable. It means physically larger. Comfort depends on your actual measurements matching the eyeglass frame size chart.

Final Score: 7/10 for the right face size. 4/10 if you guess wrong on fit.
