Protecting Your Eyes This Summer: UV Myths and Must-Knows
Summer in Aotearoa is something many of us look forward to each year. Long, bright days and warm evenings make it easy to spend more time outdoors, whether you are enjoying the beach, working in the garden or simply soaking up the light after a busy day. With all this sunshine, it is important to think about protecting your eyes from the sun. New Zealand experiences some of the strongest sunlight in the world, and this affects not only our skin but our eyes too.
At Visique Eye Spy Optometrists, we often speak with patients who are surprised to learn how much UV exposure contributes to long-term UV eye health. The effects of sunlight on the eyes are cumulative, which means small daily decisions add up over time. In this guide, we explore the realities of New Zealand UV levels, address some persistent myths and offer practical ways to support healthy, comfortable vision throughout the season.
Understanding the Impact of UV on Eye Health
The eyes are particularly sensitive to UV radiation. Over many years, excess exposure can contribute to UV damage to eyes, including cataracts and surface changes such as pterygia. Many New Zealanders recognise pterygium as “surfer’s eye”, although you certainly do not need to surf to develop it. One of the key pterygium causes is frequent time outdoors without adequate eye protection.
Because these conditions progress slowly, you may not notice a change right away. This is why good habits matter, especially in summer when the sun is highest and brightest. Sunglasses that provide strong UV protection help significantly, as does choosing shade during peak hours and staying aware of how long you are outside.
Good protection does not need to be complicated. A well-fitting pair of UV400 sunglasses filters out both UVA and UVB rays, allowing you to enjoy space and sunshine comfortably. Many people also find that polarised lenses support summer eye health by reducing glare from reflective surfaces.
Dispelling Common Myths About UV Exposure
There are several myths that can give people a false sense of security. Here are a few we hear often in practice.
Myth 1: Sunglasses are only necessary on very bright days
Even when the sky looks grey, cloudy day UV exposure remains surprisingly high. Clouds soften visible light but do little to reduce UV radiation. Wearing sunglasses consistently helps protect your eyes throughout the year, not only during clear blue days.
Myth 2: Children do not need the same level of protection
Children’s eyes are still developing, and their natural lenses let in more UV than adult eyes. Because kiwi kids often spend hours playing outside, children’s eye protection is especially important. Choosing comfortable, durable sunglasses for kids encourages habits that support healthy vision well into adulthood.
Myth 3: Dark lenses offer better protection
Lens darkness has very little to do with UV filtering. A dark tint may feel comfortable but cannot guarantee protection unless the lenses themselves are designed for it. This is why choosing sunglasses with clear UV labelling is essential for effective eye safety outdoors.
Myth 4: Polarised lenses block UV
Polarised lenses are excellent for reducing glare, which helps reduce eye strain from sun glare, especially when driving or spending time on the water. However, polarisation alone does not ensure UV filtering. When combined with a strong UV rating, you gain both clarity and comfort. These dual benefits are among the most appreciated polarised sunglasses benefits.
The Realities of Everyday Summer Exposure
Most UV exposure does not happen during planned beach days. It occurs during everyday activities such as driving, exercising outdoors or enjoying a morning walk. Each of these moments contributes to overall exposure.
Driving is a good example. Glare from the road, car bonnets and nearby water can make your eyes feel tired, particularly during summer evenings. A pair of well-fitted sunglasses helps reduce strain and allows you to stay more focused and relaxed.
Outdoor work and sport also lead to prolonged exposure. Whether you are cycling, gardening or enjoying a game of cricket, a pair of comfortable sunglasses provides protection without getting in the way of your routine.
Because UV exposure occurs in every season, year-round UV protection is something we speak about often. While sunlight feels strongest in summer, reflective surfaces in winter can also increase exposure, especially around water or snow.
Choosing Sunglasses That Support Your Eye Health
Many people ask how to choose the right sunglasses for New Zealand conditions. Here are a few simple factors to guide your decision.
1. Confirm the UV rating
Look for sunglasses labelled as offering full UV protection. This allows you to feel confident that your lenses support your UV protection for eyes no matter how bright the day becomes.
2. Consider lens type
If you spend time driving or near water, polarised lenses can make a noticeable difference to your comfort. They help manage reflections and support relaxed, clear vision during bright summer days.
3. Think about your prescription needs
If you rely on glasses for everyday tasks, prescription sunglasses NZ options allow you to maintain clear vision outdoors without juggling multiple pairs. Many people find that investing in dedicated prescription sunglasses becomes an essential part of maintaining their summer eye health.
4. Evaluate comfort and fit
Well-fitting sunglasses stay secure during outdoor activities and encourage regular wear. Choosing a frame that feels natural on your face means you are far more likely to use it consistently.
The Importance of Regular Eye Examinations
Even with diligent sun protection, regular check-ups remain essential for maintaining healthy vision. An assessment helps identify early signs of UV-related changes and allows you to discuss whether your current protection is working well for you.
