Nicolas | Opticien & Santé Visuelle on Instagram: "Lunettes pour l'observation de l'éclipse, attention à cette erreur à laquelle on ne pense pas. Tu as acheté des lunettes pour observer l'éclipse solaire du 12 août et c'est très bien, si tu la regardes avec des lunettes de soleil tu vas te brûler les yeux, et je ne te parle pas de l'observation à l'oeil nu... Mais si tu as déballé tes lunettes pour l'éclipse, même juste pour te rendre compte de comment on voit avec, tu as fait une grosse erreur. Tu les gardes de côté sans protection et une toute petite rayure, invisible à l'œil nu, peut te le faire regretter à vie, tu vas te brûler la rétine et les dégâts sur ta vue seront irréversibles. Et attention aussi aux enfants. Alors dis-moi, tu les as déballées, parce que personne ne te l'avait dit ?"
Verdict: Mostly accurate, but it overstates the need to keep eclipse glasses sealed and unused.

The video is right that ordinary sunglasses are not safe and that damaged eclipse glasses should not be used. But it is misleading to say they should never be unboxed before the eclipse or that any tiny invisible scratch automatically makes them unusable.
Claim-by-claim breakdown
- Accurate (98% confidence): Regular sunglasses are not safe for viewing a solar eclipse. NASA and the American Astronomical Society both say regular sunglasses are not safe for solar viewing.
- Accurate (90% confidence): You can safely reuse eclipse glasses if they are undamaged and compliant with the safety standard. AAS and AAO say modern eclipse glasses do not expire and may be reused if they have no scratches, punctures, tears, or other damage.
- Accurate (97% confidence): If eclipse glasses are scratched, torn, punctured, or otherwise damaged, they should be discarded. NASA says to inspect eclipse glasses before use and discard them if they are torn, scratched, or otherwise damaged; AAS gives the same advice.
- Misleading (85% confidence): You should not unwrap eclipse glasses before the day of observation because even a tiny invisible scratch could make them unsafe. Guidelines emphasize inspection and damage checks, not keeping them unopened. The video turns a caution about damaged filters into a blanket ban on unboxing.
- Accurate (88% confidence): Using damaged eclipse glasses could cause irreversible eye damage. Official eclipse-safety guidance warns that unsafe solar viewing can permanently damage vision, but it does not claim every minor defect will necessarily cause injury.
