If you're among the many people who waited too long to buy eclipse glasses and now find them sold out or delayed, there's a safe alternative that might surprise you: DIN 14 welding glass. These dark filters, commonly used in welding helmets, can protect your eyes during a solar eclipse—but only if you choose the right grade and use them correctly.
With the eclipse just around the corner, many retailers are out of certified eclipse glasses. But welding supply stores and online marketplaces like Amazon still have options. The key is understanding the DIN scale and knowing what to look for.
Why Eclipse Glasses Are Hard to Find
Solar eclipses create a surge in demand for ISO 12312-2 certified eclipse glasses. Manufacturers ramp up production, but supply often can't keep up with last-minute buyers. This year, many popular retailers sold out weeks in advance, leaving skywatchers scrambling for alternatives.

That's where welding glass comes in. Welders have used dark glass to protect their eyes from intense light for decades, and the same technology can shield your eyes from the sun during an eclipse.
What Is DIN 14 Welding Glass?
Welding glass is rated on the DIN scale (Deutsches Institut für Normung), which indicates how much light the glass blocks. The higher the number, the darker the glass. For solar eclipse viewing, the American Astronomical Society (AAS) recommends a shade number of 12 to 14.
At DIN 12 or 13, the sun may still be uncomfortably bright. At DIN 15, the image is too dark to see details. DIN 14 hits the sweet spot: it blocks enough light to be safe while still allowing you to see the eclipse clearly.
DIN 14 vs. Other Shades
| Shade | Light Transmission | Suitability for Eclipse |
|---|---|---|
| DIN 10 | Higher | Not safe |
| DIN 12 | Moderate | May be too bright |
| DIN 13 | Lower | Acceptable but bright |
| DIN 14 | Very low | Recommended |
| DIN 15 | Extremely low | Too dark |
Always check the shade number before buying. Some welding glass is unmarked or mislabeled, so purchase from a reputable seller.
Where to Buy DIN 14 Welding Glass
You can find DIN 14 welding glass at local welding supply stores, hardware stores, or online. A popular option is the PATIKIL Welding Lens Shade 14, available on Amazon for around €20.99. It comes in a pack of four 4-1/4" x 2" tempered glass plates, designed to fit standard welding helmets.
When buying, ensure the product explicitly states DIN 14 or Shade 14. Avoid generic "welding glass" without a grade, as it may not provide adequate protection.
How to Use Welding Glass for Eclipse Viewing
Welding glass alone is not a pair of glasses—it's a flat plate. You'll need to hold it securely in front of your eyes or mount it in a welding helmet or a homemade frame. Never look through the glass without ensuring it's firmly in place and free of cracks or pinholes. The longer history behind the story is traced in Andalusia Eclipse Glasses Warning: One-Minute Limit Debated.
Inspect the glass before each use. Hold it up to a bright light; if you see any light coming through other than the sun's image, discard it. Also, remember that welding glass is not designed for prolonged staring at the sun—limit your viewing to short intervals.

- Check the shade number: Only DIN 14 is recommended for eclipse viewing.
- Inspect for damage: Cracked or pitted glass is unsafe.
- Use a proper holder: Hold the glass securely or use a welding helmet.
- Supervise children: Never let kids view the eclipse without adult supervision.
- Limit exposure: Take breaks to avoid eye strain.
Safety First: What You Need to Know
Even with DIN 14 glass, you must follow safety guidelines. Never look at the sun without protection, even during an eclipse. The only exception is the brief total phase of a total solar eclipse, when the moon completely covers the sun. But if you're not in the path of totality, or during partial phases, always use protection. A closer look at the same subject appears in Solar Eclipse Glasses Demand Sparks Price Hikes and Queues.

Welding glass is a viable alternative when eclipse glasses are unavailable, but it's not a substitute for certified eclipse glasses if you can get them. The AAS recommends ISO 12312-2 glasses as the gold standard. However, DIN 14 welding glass is a recognized safe alternative.

FAQ
Is DIN 14 welding glass safe for viewing a solar eclipse?
Yes, DIN 14 welding glass is considered safe for eclipse viewing by the American Astronomical Society. It blocks enough sunlight to prevent eye damage while still allowing you to see the eclipse. However, always inspect the glass for damage and use it properly.
Can I use regular sunglasses to watch the eclipse?
No, regular sunglasses are not safe for viewing a solar eclipse. Even the darkest sunglasses let through too much sunlight and can cause permanent eye damage. Only use certified eclipse glasses or DIN 14 welding glass.
Where can I buy DIN 14 welding glass?
You can find DIN 14 welding glass at welding supply stores, hardware stores, and online retailers like Amazon. Look for products that explicitly state DIN 14 or Shade 14. A popular option is the PATIKIL Welding Lens Shade 14, available in packs of four.
How do I know if my welding glass is truly DIN 14?
Check the product packaging or the glass itself for a marking that says DIN 14 or Shade 14. If it's not marked, don't use it for eclipse viewing. Purchase from reputable sellers and avoid unmarked or generic welding glass.
