Your Eyes and the Sun: How to Protect Your Eyes in Summer Weather

Why Protecting Your Eyes in the Sun Matters

If you are travelling somewhere hot or spending long summer afternoons outside in the UK, your eyes need just as much protection as your skin. Unfiltered sunlight delivers far more than uncomfortable glare - it can gradually degrade your internal eye tissue, raising your lifetime risk of developing cataracts. While heat, wind, pollen and air conditioning can contribute to dry, irritated or watery eyes.

Protecting your eyesight doesn’t mean staying inside; it’s all about wearing UV-blocking shades, being aware of peak midday rays, and soothing dry eyes before inflammation sets in.

At 121 Pharmacy, we have put together this guide to help you understand how to protect your eyes in sunny weather, what can cause summer eye irritation and what can you do if your eyes become dry, itchy or uncomfortable?

How Does the Sun Affect Your Eyes?

We need sunlight, but unfiltered UVA and UVB radiation does quiet, gradual harm. According to the RNIB, long-term UV exposure steadily damages internal ocular structures, making you considerably more susceptible to cataracts later in life. The NHS warns that high-intensity exposure can also trigger photokeratitis. This is a sharp, temporary burn to the cornea that causes sudden redness, swelling, and severe light sensitivity.

Direct overhead sun is only part of the problem. UV bounces easily off water, sand, and pale pavements, which means your eyes absorb reflected rays even when you are resting in partial shade. This is just as relevant in the UK as it is overseas. British summer days deliver plenty of strong radiation, and low-angled sun during morning or evening driving creates fatiguing glare that demands eye protection.

Sunglasses Are One of the Best Ways to Protect Your Eyes

When it comes to summer eye protection, sunglasses are one of the simplest and most effective choices.

However, not all sunglasses offer the same level of protection. Rather than choosing a pair based purely on how dark the lenses are or how they look, check that they provide appropriate UV protection and meet the relevant quality standards.

The College of Optometrists recommends choosing sunglasses with good UV protection and looking for the appropriate British Standard, CE or UKCA marking. The RNIB similarly recommends sunglasses carrying a CE mark or British Standard BS EN ISO 12312-1.

Darker lenses do not necessarily mean better UV protection. What matters is whether the lenses have an effective UV filter.

For everyday summer use, larger frames or wraparound styles can also be useful because they reduce the amount of sunlight entering from the sides. This can be particularly helpful if you are sensitive to bright light or spend a lot of time outdoors.

If you wear prescription glasses, speak to your optician about suitable prescription sunglasses or lenses with UV protection.

Don't Forget Your Hat

A wide-brimmed hat is another simple way to reduce the amount of direct sunlight reaching your eyes.

Wearing sunglasses alongside a hat provides an additional layer of protection and can make bright summer days more comfortable. A hat can also help shade your face, ears and neck, making it a useful part of your wider approach to sun safety.

This is particularly important for children. Young eyes can be more susceptible to UV exposure because children's pupils are larger and their lenses are clearer, allowing more UV radiation to reach the retina. The College of Optometrists recommends that children wear sunglasses and a hat when spending time in the sun.

Don't Look Directly at the Sun

This may sound obvious, but it is an important reminder, particularly during very bright weather or while watching events outdoors.

Never look directly at the sun, even while wearing sunglasses. Doing so can cause permanent damage to the eyes. The NHS specifically advises against looking directly at the sun.

If you are watching an eclipse, use specialist eclipse viewing equipment designed specifically for that purpose. Ordinary sunglasses are not suitable for safely viewing the sun directly.

Summer Can Trigger Dry and Irritated Eyes

Summer creates a combination of environmental factors that strip moisture from the surface of the eye, leaving them red, stinging, or gritty.

Common summer factors include:

• Air Conditioning - Car vents, planes, and indoor cooling quickly evaporate your tear film.
• Warm Wind and Heat - Outdoor breezes speed up moisture loss across the cornea.
• Travel Screen Time - Staring at phones or tablets on long journeys cuts your natural blink rate in half.

Dry eyes don’t always feel dry. Irritation often triggers excessive watering as your eyes attempt to flush the surface with reflex tears.

To protect the ocular surface and reduce irritation, the following over-the-counter options help:

• Lipid-Replenishing Drops - Formulations like EvoTears Eye Drops coat the tear film to stop rapid evaporation in air-conditioned spaces.
• Eyelid Mists - Sprays such as Viz Opti Double Action Dry Eyes Eyelid Mist offer quick, on-the-go hydration if you struggle with eye drops.

If your symptoms persist, ask a pharmacist or optometrist to help identify the exact trigger.

Hay Fever Can Make Summer Eye Symptoms Worse

Summer weather and rising pollen counts create a frustrating double-hit for your eyes. If your tear film is already thinned by warm breezes or dry air conditioning, airborne pollen penetrates the ocular surface much faster, leading to sudden burning, grittiness, and heavy watering.

Try not to rub your eyes when pollen flares up. Rubbing creates friction and forces mast cells to dump more histamine into the surrounding tissue, which escalates the problem.

Tackle the problem with the following practical habits:

• Seal out drafts - Keep bedroom and living room windows closed when local pollen forecasts read high.
• Wash outdoor residue off - Shower, wash your hair, and gently wipe your eyelids after outdoor activities.
• Swap out your clothes - Change out of garments worn outdoors so you don't carry allergens into your living space.

For hayfever relief:

• Opticrom Hayfever & Allergy Eye Drops - These will give you targeted clinical action against seasonal allergic conjunctivitis, soothing irritated tissues.

Because hay fever and evaporative dry eye often share identical symptoms, speak to your pharmacist if you need help pinpointing the root cause.

Protect Your Eyes When Swimming

Swimming is one of the best ways to cool down on a hot summer's day, but your eyes can be exposed to irritants in both swimming pools and open water.

Chlorinated pool water can irritate the eyes, while open water may contain microorganisms that can cause eye infections. The College of Optometrists recommends using watertight swimming goggles to help protect your eyes.

If you wear contact lenses, take extra care. Always remove contact lenses before swimming. If you need vision correction while swimming, prescription swimming goggles may be an option to discuss with your optometrist.

Lastly, try to avoid rubbing your eyes after swimming. If your eyes feel irritated, rinse your face and allow your eyes to settle rather than repeatedly touching them.

Be Careful Around Reflective Surfaces

You might associate intense UV exposure with tropical holidays, but reflective surfaces can increase the amount of sunlight reaching your eyes anywhere.

Water, sand and snow are particularly reflective, but the NHS also highlights concrete as a surface that can reflect sunlight. This is worth remembering if you are spending the day in a garden, sitting beside a pool or walking around a bright outdoor area.

This is another reason why sunglasses should be part of your everyday summer routine rather than something you only pack for your holiday abroad.

Simple Ways to Protect Your Eyes This Summer

Protecting your eyes does not require a complicated routine. A few straightforward habits can make a meaningful difference throughout the summer.

Wear good quality sunglasses with UV protection whenever you are outside in bright conditions. Pair them with a wide-brimmed hat when possible, particularly during periods of strong sunshine. Seek shade when the sun is particularly intense and never look directly at the sun.

Remember to stay hydrated, especially during hot weather, and take care around swimming pools and open water. If you experience dry, irritated or allergy-related eye symptoms, consider speaking to a pharmacist about suitable eye care products.

It is also sensible to keep up with regular eye tests. An eye examination is not simply about checking whether you need new glasses. Regular appointments can help identify changes in your eye health and vision.

When Should You Get Help for Eye Problems?

Most minor summer eye irritations are temporary, but you should not ignore significant or unusual symptoms.

Seek urgent medical attention if you experience sudden changes to your vision, severe eye pain, significant sensitivity to light, a serious eye injury or a sudden loss of vision.

If your eyes remain red, painful, swollen or irritated despite taking steps to manage the symptoms, speak to a healthcare professional. The same applies if you regularly experience dry eyes or recurring allergy symptoms that are interfering with your everyday life.

FAQs: Protecting Your Eyes in the Sun

Protecting your eyes in the sun is an important part of looking after your overall eye health, particularly during the brighter summer months. Here are answers to some common questions about sunglasses, UV exposure, dry eyes and summer eye care.

Do I really need sunglasses in the UK?

Yes. UV exposure is not limited to hot or tropical countries. Sunny days in the UK can expose your eyes to UV radiation, while glare can also make bright conditions uncomfortable. Look for sunglasses that provide UV protection and have the appropriate quality marking, such as the CE or UKCA mark or relevant British Standard.

Can sunglasses help with hay fever?

Sunglasses can reduce exposure to wind, bright sunlight and some airborne particles around the eyes, which may make outdoor conditions more comfortable. However, they are not a treatment for hay fever. If you experience itchy or watery eyes due to allergies, speak to a pharmacist about suitable treatments.

Why are my eyes dry in summer?

Hot weather, wind, air conditioning, dehydration and prolonged screen use can all contribute to dry or uncomfortable eyes. If your symptoms continue, a pharmacist, optometrist or other healthcare professional can help you identify the likely cause and recommend appropriate treatment.

Can I wear contact lenses in the sun?

Contact lenses can be worn outdoors, but they should not be considered a replacement for sunglasses. If your lenses include UV protection, they may provide some additional protection, but they do not cover the entire eye. Sunglasses are still recommended.

Can I wear contact lenses while swimming?

It is generally recommended that contact lenses are removed before swimming. The College of Optometrists recommends using watertight swimming goggles to protect the eyes and taking contact lenses out before entering the water.

Enjoy the Sunshine While Looking After Your Eyes

Summer should be about enjoying the outdoors, not worrying about irritated or uncomfortable eyes. A few simple habits can help you make the most of the sunshine while taking better care of your vision.

Wear UV-protective sunglasses, use a wide-brimmed hat, seek shade, stay hydrated and take extra care around swimming pools and reflective surfaces. If dry eyes, hay fever or irritation are making summer less enjoyable, there are also pharmacy options that may help manage suitable symptoms.
