Best Eclipse Glasses and Gear for the 2027 Total Eclipse

One pair of ISO 12312-2 certified eclipse glasses is the single most important thing you will buy for 2 August 2027, and it costs only a few euros. Everything else on the gear list is optional. On eclipse day in southern Spain, the Sun climbs to around 38° for a late-morning total eclipse, and for every minute except the brief phase of totality itself, that Sun is bright enough to cause permanent eye damage without proper protection.

The reassuring part: your essential kit is cheap and small enough to fit in a pocket. The trap that catches people is timing, not budget. Certified glasses sell out in the weeks before a major eclipse, so the smart move is to buy early and buy enough for everyone in your group. This guide covers what you actually need, what is nice to have, and, most importantly, how to use each item safely.

The one thing you cannot skip: eclipse glasses

Regular sunglasses are not eclipse glasses. Even very dark sunglasses transmit thousands of times too much light for direct solar viewing. What you need are filters certified to the international standard ISO 12312-2:2015, which block essentially all visible, infrared and ultraviolet light except a tiny, safe amount. Only look at the partially eclipsed Sun through these.

A multi-pack is the sensible choice: you want spares in case one gets scratched, and everyone standing with you needs their own pair. Before eclipse day, inspect each pair in bright light, if the filter is scratched, punctured or peeling, throw it out and use a fresh one.

Buy early: this is the mistake people regret

Demand for certified glasses spikes in the final weeks before a major eclipse, and stock runs dry. Ordering months ahead costs the same and removes the risk entirely.

1. Order early. Buy your glasses well before summer 2027, not the week of the eclipse.
2. Buy for the whole group. Count heads, then add a couple of spares.
3. Check the certification. Look for the printed "ISO 12312-2" marking on the glasses themselves.
4. Store them flat. Keep filters away from scratches and heat until the day.

Protecting cameras, binoculars and telescopes

Here is the rule that surprises newcomers: any optical instrument concentrates sunlight, so pointing an unfiltered camera, binocular or telescope at the Sun is more dangerous than the naked eye, not less. A telescope can focus enough heat to cause instant, permanent injury, and it can melt the instrument's own internals. The filter must go on the front of the optic, over the objective lens or aperture, so the light is blocked before it enters and is magnified.

For photography, that means a purpose-made solar filter sized to your lens or telescope aperture. For the total phase itself, experienced photographers briefly remove the filter to capture the corona during totality only, then replace it the instant totality ends. If you plan to shoot the event, our guide to eclipse photography for the Sun and Moon walks through exposures and filter timing in detail.

Optional: binoculars for the corona

You do not need magnification to enjoy a total eclipse, the naked-eye view during totality is the main event. But a pair of astronomy binoculars can reveal delicate structure in the corona and make the partial phases more engaging, provided they are properly filtered.

The safe way to use binoculars around an eclipse: keep front solar filters fitted over both objective lenses for the entire partial phase. Only during the brief totality, with the Sun fully covered, may experienced observers remove the filters to view the corona, and the filters go straight back on before the first sliver of sunlight returns. If that timing makes you nervous, skip the binoculars and simply drink in the naked-eye view; it is spectacular on its own.
