As the near-total solar eclipse looms, a timely reminder before the evening of 12 August 2026: using inadequate protection can cause irreversible damage to the retina. Looking at the Sun without proper protection can lead to solar retinopathy—a retinal burn that may leave lasting, permanent effects.
The DGCCRF reminds us that glasses used to observe an eclipse must be specifically designed for that purpose and must block all ultraviolet rays. But can you still use the glasses bought for the occasion of the total eclipse in 1999, or should you avoid using old eclipse glasses? Here’s a briefing on the warnings and official recommendations.
Experts emphasize three key points above all: eyewear must comply with the ISO 12312-2 standard, bear no scratches, punctures or deformations, and have a clearly identifiable origin and manufacturer.
In theory, a perfectly preserved pair since 1999 could still filter light effectively. But in practice, after more than 25 years in storage, it’s very hard to guarantee that the filters haven’t suffered any time-related degradation, from heat or humidity.
The problem isn't the manufacturing date itself: the real risk is the impossibility of guaranteeing their condition after many decades. That's precisely why authorities urge replacing older glasses with a newer, certified model, rather than taking any risk.
Be cautious with older eclipse glasses (there were plenty for the total solar eclipse of 1999, etc.): the filtering power can fade with time and, even more so, if storage was careless, the glasses may have suffered damage (cracks, holes in the film...). We should therefore opt for newer glasses (under one year old) says the Observatoire de Paris on its site.
Before watching the solar eclipse on August 12, check several essentials: the ISO 12312-2:2015 or ISO 12312-2 designation must be present, the CE mark must appear, a French-language instruction leaflet along with the manufacturer or distributor details must be provided, and the filters must be perfectly intact.
As the event draws near, authorities are warning about a proliferation of counterfeit certified glasses being sold on certain platforms or at outlets with little oversight. Prudence is advised, and it’s wiser to head to a pharmacy or an optician rather than buying a pair online!
The answer is no. Even very high-end sunglasses do not filter sunlight sufficiently to permit direct viewing of the Sun. Only glasses specially designed for eclipses meet the safety requirements.
To safely watch the solar eclipse on August 12, 2026, authorities keep the guidance simple: wear new glasses, ISO 12312-2 certified, in pristine condition and bought from a trusted seller. Faced with a risk of permanent vision damage, the price of a brand-new pair is well worth it compared with an uncertain protection.
