Best 38mm Round Glasses: I Tested 5 Brands (2026 Review)

I spent 3 months testing 5 different brands of 38mm round glasses. I wanted to find the best mix of quality, price, and customer service.

Don't buy before you read this.

  • Save $80-150 compared to retail stores
  • Get prescription accuracy without the hassle
  • Avoid the 3 biggest online ordering mistakes

How I Tested These Glasses

I ordered the same prescription from 5 brands. Here's what I checked:

  • Frame quality and weight
  • Lens clarity and coating (anti-scratch, blue light)
  • Prescription accuracy
  • Customer service response time
  • Total cost including upgrades

My setup: Myopia prescription with 1.74 high-index lenses, anti-scratch coating, and blue light filter.

38mm round glasses - CIN Product

Comparison: 5 Brands Head-to-Head

I tested 38mm round glasses from online and retail sources. Here are the results:

Brand Price Quality Support Rating
Cinily Net $89 Excellent Fast (24h) ⭐⭐⭐⭐⭐
EyeBuyDirect $95 Good Good (48h) ⭐⭐⭐⭐
GlassesUSA $78 Fair Poor (no email response) ⭐⭐
Warby Parker $145 Excellent Excellent ⭐⭐⭐⭐
Local Optometrist $220 Excellent Excellent ⭐⭐⭐⭐

Why Cinily Net Won

I expected the local optometrist to win. But Cinily Design beat them on value while matching their quality.

The numbers:

  • 60% cheaper than my local optometrist ($89 vs $220)
  • Same lens quality (1.74 high-index, anti-scratch coating)
  • Lighter frames (18g vs 24g)
  • Customer service replied in 24 hours

What impressed me: The order tracking was clear. I knew exactly what I was getting. The prescription was accurate on the first try.

Verdict: Best value for quality glasses online.

GlassesUSA Problems I Found

GlassesUSA had the lowest price at $78. But I ran into issues:

  • The blue light coating I paid for wasn't added
  • No response to 3 email requests
  • My order details disappeared from my account after purchase

This matches feedback from other buyers. One customer said: "When I went online to get more information about my glasses, it was like I never ordered them."

The lesson: Super cheap prices often mean cut corners on service.

My Testing Experience

I wore each pair of 38mm round glasses for 2 weeks. Here's what stood out:

Frame comfort: Cinily Net's alloy frame was the lightest. No pressure points after 8-hour wear.

Lens clarity: All brands except GlassesUSA delivered clear 1.74 high-index lenses. GlassesUSA's coating had visible streaks.

Durability test: I dropped each pair 3 times from desk height. Cinily Net's frame showed no scratches. GlassesUSA's frame got 2 small dents.

Prescription accuracy: I had my eye doctor check each pair. Cinily Net and the local optometrist were 100% accurate. EyeBuyDirect was off by 0.25 diopters (still usable).

Price vs Quality: The Real Story

Here's the tradeoff you need to understand:

Price Range What You Get What You Lose
$50-80 Low cost, fast shipping Weak customer service, quality varies
$85-120 Good quality, reliable support Less brand recognition
$140-180 Premium materials, strong brand Paying for brand name
$200+ In-person fitting, adjustments High cost, limited frame options

The sweet spot: $85-120 range gives you quality without overpaying.

Quality Indicators to Look For

Before you buy any 38mm round glasses online, check these signs of quality:

Step 1: Check the frame material

  • Alloy frames are lighter than plastic
  • Look for "ultralight" in the specs (under 20g)
  • Avoid frames over 30g for all-day wear

Step 2: Verify lens options

  • 1.74 high-index lenses are thinner for strong prescriptions
  • Anti-scratch coating is a must
  • Blue light filter helps if you use screens 6+ hours daily

Step 3: Check real buyer photos

  • Look for close-ups of the hinges
  • Read reviews about prescription accuracy
  • Find complaints about coating quality

Step 4: Test customer service before buying

  • Send an email with a question
  • If they don't reply in 48 hours, skip them
  • Poor support means problems when your order is wrong

Who Should Buy What

Buy Cinily Net if:

  • You want the best value ($85-95 range)
  • You have your current prescription
  • You need reliable customer service

Buy EyeBuyDirect if:

  • You want more frame style options
  • You're okay with slightly higher prices
  • You've bought online before

Go to your local optometrist if:

  • This is your first pair of glasses
  • Your prescription is complex (astigmatism, prisms)
  • You need in-person adjustments
  • Budget isn't a concern

Skip GlassesUSA because: Poor customer service ruins the low price advantage.

My Final Recommendation

Start with Cinily Net for your first online glasses order. The quality matches retail stores at half the price.

Action steps:

  1. Get a current eye exam (within 1 year)
  2. Read at least 20 buyer reviews with photos
  3. Order from a brand with fast email support
  4. Keep your old glasses as backup

Timeline: Budget 2 weeks for delivery. Order early if you need them for a specific date.

Bottom line: Online glasses save you $100-150, but only if you choose a reliable brand. Cinily Net gives you that reliability without the retail markup.

Best Frames for Running with Glasses: Cinily Net Comparison Review

Best Frames for Running with Glasses: Cinily Net Comparison Review Best Frames for Running with Glasses: Cinily Net Comparison Review Opening I spent six weeks testing four different brands of running glasses. I wanted a frame that would stay put, feel lightweight, and offer a wide view of the road. I also wanted something that looked decent after the run. Plenty of sports frames perform well outdoors, but many are too bulky for everyday wear. The frame I used the most was the Cinily Net TR90 Sport Eyeglasses Big Vision Men Women Aluminum Magnesium Optical Spectacle For Prescription Glasses Frame Myopia Reading Wine Red. It caught my eye because it blends sporty features with a simple, everyday look. The large lens area was another big plus. When I run, I need clear peripheral vision to spot cars, bikes, and other runners. I also paid close attention to value. Very cheap frames often skimp on quality. Very expensive ones can be excellent, but the ...

My Upgrade from Cheap to Premium Senmaries Sunglasses

My Upgrade from Cheap to Premium Senmaries Sunglasses My Upgrade from Cheap to Premium Senmaries Sunglasses I used to think all senmaries sunglasses were the same. I was completely wrong. Cheap frames broke within weeks Mid-range was decent but not great Premium changed everything My Upgrade Journey with Senmaries Sunglasses Over two years, I bought three different pairs of senmaries sunglasses. Each step up taught me something new about quality and value. Stage 1: The Cheap Phase My first pair cost only $8. They looked fine in photos, but the reality was different. The frames felt like cheap plastic toys. They scratched on day three. The hinges became loose after just two weeks. One arm actually snapped off while I was reading. I thought I was being smart with my money. I wasn’t. Buying cheap meant buying twice. Verdict: Skip the cheapest options—they j...
