How to Use Solar Eclipse Glasses
The spectacle is cosmic. The routine should be simple: check, cover, look, turn away, remove. Practise it before eclipse day, especially with children.
1. Inspect every pair
Check both sides of the filter. Do not use glasses that are scratched, punctured, torn, creased through the viewing area or separating from the frame. Check the printed model and instructions. Tember models C2026, B2026, G2026, P2026 and Y2026 are listed on certificate CE-PC-260615-499-01-9A; see Compliance.
Verify this certificate directly with CCQS: enter CE-PC-260615-499-01-9A on the CCQS certificate verification page.
2. Put them on before facing the Sun
Stand still and look down or away. Fit the eclipse glasses securely, then turn toward the Sun. If you wear prescription glasses, keep them on and place the solar viewer over them or hold it securely in front.
3. Keep protection on during partial and annular phases
A Sun that is 99% covered is still a partial eclipse. Ordinary sunglasses are not enough. During an annular eclipse, the bright ring remains direct sunlight, so glasses stay on throughout.
4. Understand totality
Only observers inside the confirmed path of totality may remove glasses, and only while the Moon completely covers the Sun's bright face. Replace them immediately when any bright point returns. If your location is partial or you are unsure, keep them on. Check our Spain 2026 guide.
5. Turn away before removing them
After viewing, turn your face away from the Sun. Only then remove the glasses.
Children, smartphone photos and optical equipment
Not for children under 3. Ages 3+ need close adult supervision. Do not use the eclipse glasses on a phone or camera. For casual, non-magnified smartphone photography, use only the separate Tember phone-camera filter supplied with the pack, secured over every active lens before aiming at the Sun. Protect your eyes separately and look only at the screen. The phone filter is outside the EN ISO 12312-2 assessment for the direct-viewing glasses. Optical viewfinders and magnifying equipment need their own purpose-built front-mounted solar filter.
After use
Store glasses flat, dry and protected from heat, pressure and sharp objects. Inspect them again before every use. Follow the supplied IFU and any obsolescence period printed on the product or packaging.
