Watery Eyes: What’s Really Going On and How to Fix It

We all know to put on sunscreen when the sun comes out. But how many people think about their eyes with the same urgency? In my experience, almost nobody – until something actually starts bothering them. Here’s what genuinely matters for your eyes over a Scottish summer, and what’s more marketing than medicine.
Ultraviolet radiation doesn’t just burn skin. Long-term UV exposure contributes to cataracts, pterygium (a growth on the surface of the eye), and macular degeneration. The awkward truth is that a Scottish summer still produces enough UV to matter, especially between 10am and 4pm, and especially around water, sand, or when the sun is low and directly in your line of sight.
The good news is that protection is straightforward – it just needs to be the right kind.
Polarised lenses cut glare from reflective surfaces (wet roads, water, car bonnets) on top of UV protection – useful for driving and time near water, but not essential for everyday wear
The sunglasses test If your sunglasses don’t have a CE mark or UV400 label, they might be doing more harm than good. A dark tint without UV protection widens your pupils while letting damaging light through – the worst of both worlds. |
If your eyes are red, itchy, and watering every June, you already know this one. Antihistamine tablets help the nose and the sneezing, but they’re not always enough for the eyes specifically. As an IP-qualified practice, we can prescribe targeted eye drops for allergic eye reactions directly – stronger and more specific than anything over the counter – without you waiting for a GP appointment. If drops alone aren’t enough, or your eyes feel dry and gritty on top of the allergy symptoms, our dry eye clinic can assess what’s actually going on beneath the surface.
People spend more time outdoors in summer, but screen hours don’t tend to drop – they just shift to phones and tablets instead of desktop monitors. The same reduced blinking and dry-eye cycle applies. If that’s something that bothers you year-round, our piece on blue light glasses and what actually causes screen fatigue is worth a read.
Children’s eyes are more vulnerable to UV than adults’ – their lenses are clearer and let more UV through to the retina. Sunglasses with proper UV protection aren’t a luxury for kids, they’re genuinely important. And more time outdoors in summer is actually protective against myopia progression, so getting them outside (with sunglasses on) is a double win.
If you’re due an eye test anyway, summer is a good time to get it done – we can check your UV protection, assess any hayfever-related irritation, and make sure your prescription is right before the holidays. Get in touch or call 0141 427 4040.

Yes - long-term UV exposure contributes to cataracts, macular degeneration, and surface growths on the eye. Protection with UV400-rated sunglasses significantly reduces this risk.
Not necessarily. What matters is the UV rating (UV400 or CE mark), not the price. A cheap pair with proper UV protection outperforms an expensive fashion pair without it.
Yes - as an IP-qualified practice, we can prescribe targeted anti-allergy eye drops directly, without a GP referral. These are often more effective than over-the-counter options.
Yes - children's eyes are more vulnerable to UV damage than adults' because their lenses are clearer and let more UV through. Sunglasses with proper UV protection are genuinely important, not just cosmetic
Both work, but prescription sunglasses give better optical quality and full UV coverage. We can make up polarised prescription sunglasses in your correction if that's something you'd find useful.
