Adam RafaelMarch 2026 is shaping up to be the best month for northern lights viewing in nearly a decade — and thousands of UK residents are already scanning the skies. But as aurora mania peaks, ophthalmologists have a clear message: looking up doesn't mean looking carelessly.
Why March 2026 is special for aurora hunters
The spring equinox creates what scientists call the "Russell-McPherron effect": Earth's magnetic field aligns in a way that makes it significantly easier for solar wind to penetrate and trigger geomagnetic storms. Combined with the current solar maximum — the peak of the sun's approximately 11-year activity cycle — this makes late March 2026 one of the most aurora-active periods since the mid-2010s.
The Met Office confirmed this week that geomagnetic activity has been elevated throughout March, with several KP5+ events already recorded. AuroraWatch UK, run by Lancaster University, has issued multiple amber and red alerts this month. Visibility has been reported as far south as Yorkshire and Wales, with the strongest displays seen across Scotland's Highlands and Islands.
The last comparable period was during the September 2024 solar storm, when the aurora was visible across much of England — a rare event that drew thousands of people outdoors late at night, many of them ill-prepared for the experience.
Can the aurora damage your eyes?
The short answer is no — the aurora itself poses no direct risk to vision. Unlike a solar eclipse, the northern lights are not a concentrated source of harmful radiation. They occur when charged particles from the sun excite gases in the upper atmosphere at altitudes between 100 and 300 kilometres, producing the characteristic greens, pinks and purples. The light reaching your eyes is soft, diffuse and entirely safe to observe directly.
However, the conditions around aurora watching are a different matter. Ophthalmologists at leading UK eye health clinics have noted a consistent pattern: aurora season brings a rise in eye-related complaints that have nothing to do with the lights themselves, and everything to do with how people watch them.
The real eye risks in aurora season
Blue light exposure from screens. Most aurora chasers spend hours before and during a display staring at phones, monitoring apps and aurora forecast websites. Prolonged blue light exposure — especially at night, when the eyes are adapted to low light — can disrupt circadian rhythms and cause digital eye strain. Symptoms include dry eyes, blurred vision and headaches. An ophthalmologist can assess whether you need dedicated blue-light filtering lenses, particularly if you already wear glasses.
Night vision and sudden light transitions. Going from a brightly lit indoor space to a dark field and back again, repeatedly, over several hours stresses the eye's adaptation mechanisms. People with early-stage glaucoma or retinal conditions may be particularly sensitive to these transitions, though they might not yet have a diagnosis.
Cold and dry air. Outdoor aurora viewing in Scotland or northern England in March means exposure to cold, dry air for potentially hours at a time. This is one of the leading triggers of dry eye syndrome — a condition estimated to affect 17 % of UK adults, according to the College of Optometrists. Symptoms include stinging, a gritty sensation and intermittent blurring. Lubricating eye drops can help, but if symptoms are frequent, an ophthalmology consultation can identify whether there's an underlying cause that requires treatment.
Fatigue and vision quality. Sleep deprivation — which comes naturally with late-night aurora watching — measurably reduces visual sharpness, reaction time and the ability to distinguish contrast. For people who drive after a night of aurora chasing, this is a genuine safety risk that shouldn't be underestimated.
When is a good time to see an ophthalmologist?
Many people treat eye health as reactive — they book an appointment only when something goes obviously wrong. But ophthalmologists consistently argue for regular check-ups, particularly if you notice any of the following:
- Floaters that have appeared or increased suddenly
- Brief episodes of flashing lights in your peripheral vision
- Difficulty adjusting to light changes
- Persistent dryness or discomfort that doesn't resolve with over-the-counter drops
- Any change in the quality of your central vision
These symptoms don't necessarily indicate a serious condition — but some of them, such as sudden floaters combined with flashes, can signal a retinal tear that requires urgent attention. An ophthalmologist can examine the back of the eye with imaging equipment that a standard optician visit may not include.
How to enjoy the aurora safely
To make the most of what could be the peak aurora week of 2026 without straining your eyes:
- Spend 20 minutes in darkness before going outside to allow your night vision to fully adapt
- Avoid looking at your phone screen for at least 10 minutes before trying to spot the aurora
- Use red-light mode on your phone if you need to check apps — red light preserves night vision far better than white or blue
- Wear wraparound glasses or goggles in cold, windy conditions to protect against dry eye
- Limit total outdoor exposure to two to three hours and give your eyes rest time indoors between sessions
Book an eye health consultation
If the aurora season has reminded you that you haven't had a comprehensive eye examination recently — or if you've noticed any changes in your vision this month — Expert Zoom connects you with ophthalmologists and eye health specialists for online consultations across the UK. An initial assessment can provide clarity on your eye health status and flag any issues before they become serious.
The northern lights are extraordinary. Your vision is worth protecting so you can keep watching them for decades to come.
