As summer approaches in the UK, many of us look forward to longer days, warmer weather, and time spent outdoors or travelling abroad. While we are often mindful of protecting our skin from the sun, eye health is frequently overlooked. However, increased exposure to sunlight, heat, and environmental factors during summer can pose significant risks to your vision.
As a Consultant Ophthalmologist specialising in cataract and glaucoma, Gurjeet Jutley often sees patients whose eye conditions are influenced or exacerbated by prolonged exposure to ultraviolet (UV) light and other seasonal factors. Taking simple, preventative steps can help protect your eyes and preserve your vision in the long term.
Why Eye Protection Matters in Summer
Sunlight contains harmful UVA and UVB rays, which can damage both the surface and internal structures of the eye. Over time, excessive exposure to UV radiation has been linked to conditions such as:
- Cataracts
- Age-related macular degeneration
- Corneal damage (photokeratitis)
- Growths on the eye surface (such as pterygium)
Unlike some other conditions, this damage is often cumulative and irreversible, making prevention essential.
Choosing the Right Sunglasses
Sunglasses are not just a fashion accessory, they are a vital tool in protecting your eyes.
When selecting sunglasses, ensure they:
- Provide UV400 protection, blocking 100% of UVA and UVB rays
- Carry the CE mark or British Standard (BS EN ISO 12312-1)
- Offer good coverage, ideally with larger or wraparound frames
It is important to note that contact lenses with UV filters do not provide full protection, and poorly made or counterfeit sunglasses may offer little to no defence against harmful rays.
Even on cloudy days, UV rays can penetrate through clouds, so regular use of protective eyewear is recommended.
Avoid Peak Sun Exposure
The sun is strongest between 11am and 3pm, and during this time UV exposure is at its highest. Where possible, seek shade and wear a wide-brimmed hat in addition to sunglasses to provide further protection.
Be particularly cautious near reflective surfaces such as water, sand, or pavements, which can intensify UV exposure.
Protecting Your Eyes While Swimming
Swimming is a common summer activity, but both chlorinated pools and natural bodies of water can irritate the eyes.
- Chlorine can strip away the tear film, leading to dryness and discomfort
- Saltwater may cause redness and irritation
- Bacteria in water can increase the risk of infection
Wearing well-fitted swimming goggles can help protect your eyes. It is also advisable to avoid swimming with contact lenses, as they can trap harmful microorganisms.
Preventing Irritation from Sun Cream and Debris
Sun cream is essential for skin protection, but it can irritate the eyes if applied too close to the eye area.
- Avoid spraying sunscreen near your face
- Apply carefully around the eyes
- If irritation occurs, rinse immediately with clean water
Similarly, sand and dust can easily enter the eye during outdoor activities. Avoid rubbing your eyes, as this can cause further irritation or even corneal damage.
Eye Safety During Outdoor Activities and DIY
Summer often brings an increase in outdoor projects and DIY activities. When working with tools, chemicals, or in dusty environments, wearing appropriate protective eyewear is essential.
Polycarbonate lenses are particularly effective as they are lightweight, durable, and impact-resistant.
Managing Dry Eyes While Travelling
Travel, particularly long journeys by car or aeroplane, can contribute to dry eyes.
- Air conditioning can reduce moisture, causing irritation
- Cabin air on flights is dry and recirculated
To maintain comfort:
- Stay well hydrated
- Direct air vents away from your face
- Use lubricating eye drops if needed
- Avoid wearing contact lenses for extended periods during flights
Hydration and Overall Eye Comfort
Staying hydrated plays an important role in maintaining healthy tear production. Dehydration can lead to dry, uncomfortable eyes and blurred vision.
Drinking sufficient water and maintaining a balanced diet rich in nutrients can support overall eye health, particularly during warmer months.
A Proactive Approach to Eye Health
Summer is a time to enjoy outdoor activities and travel, but it also brings increased exposure to environmental risks that can affect your eyes. By taking simple precautions, such as wearing appropriate sunglasses, protecting your eyes during activities, and maintaining hydration, you can significantly reduce the risk of damage.
