Why UV Protection for Your Eyes is Essential in New Zealand
As New Zealanders, we're all too familiar with the sun’s intensity. We’re quick to apply sunscreen to our skin before heading outdoors — but there’s one area many people forget: our eyes.
Unlike skin, you can’t apply sunscreen to your eyes, which makes UV protection for your eyes a vital part of your everyday health routine. And because New Zealand has some of the highest UV levels in the world, the risks here are even greater.
How UV Radiation Affects Eye Health
UV rays from the sun come in two forms that affect the eyes differently:
UVA rays go deep into the eye and can damage the retina, leading to conditions like age-related macular degeneration.
UVB rays are more intense on the eye’s surface, increasing the risk of cataracts, pterygium, and photokeratitis (a type of painful sunburn on the cornea).
Because of New Zealand’s thin ozone layer and clear atmosphere, UV exposure is stronger here than in many other countries. In fact, Healthify NZ reports that we experience around 40% more UV radiation than similar latitudes in the Northern Hemisphere.
What Happens If You Don’t Protect Your Eyes?
Without protection, UV radiation builds up over time, leading to both short- and long-term eye damage.
Short-Term Risks:
Photokeratitis: Essentially a sunburn of the eye — causes pain, tearing, redness, and temporary vision loss.
Photoconjunctivitis: Inflammation of the eye’s surface due to too much UV.
Long-Term Risks:
Cataracts: Clouding of the lens that reduces vision.
Macular degeneration: Damage to the retina that can lead to vision loss.
Pterygium: A fleshy growth on the white of the eye that may need surgical removal.
Increased risk of eye and eyelid cancers.
UV damage is cumulative — so the more unprotected exposure you have over time, the higher your risk.
The Truth: You Can’t Sunscreen Your Eyes — So You Need to Shield Them
Protecting your eyes from UV rays is simple but incredibly important. Here’s how:
1. Wear Sunglasses That Block 100% UV
Not all sunglasses are created equal. Look for lenses that:
Block 100% of UVA and UVB rays
Are certified to AS/NZS 1067:2003 standards
Have a wraparound shape to protect from side exposure
Fashion sunglasses may look great but might not offer the full protection your eyes need.
2. Use Prescription Glasses with UV Protection
If you wear prescription glasses, ask your optometrist about:
UV-tinted lenses; These can be perfectly clear to look through while still giving UV protection
Photochromic lenses that darken in sunlight
Polarised lenses for reducing glare (great for driving and water activities)
3. Consider UV-Blocking Contact Lenses
Some contact lenses come with built-in UV protection — but they don’t cover the whole eye. Always pair them with sunglasses for complete safety.
4. Wear a Hat
A wide-brimmed hat can reduce UV exposure to your eyes by up to 50%. Combine this with quality sunglasses for maximum protection.
5. Be UV-Smart Year-Round
UV rays are present every day, even on cloudy or overcast days. They reflect off water, concrete, and even snow — so it’s important to protect your eyes no matter the season.
Do UV-Coated Lenses Really Make a Difference?
Yes, absolutely. Research shows that UV-coated lenses significantly reduce the risk of eye damage. According to the Cancer Society NZ, only lenses labeled UV400 or “100% UV protection” offer full coverage.
Wearing non-protective lenses can be worse than wearing nothing — because your pupils dilate behind tinted lenses, allowing even more UV rays in if the lenses aren't properly coated.

When Should You Bring Your Child to the Optometrist?
When Should You Bring Your Child to the Optometrist?
As parents, we want the best for our children, and that includes ensuring their vision is clear and healthy! But knowing when to take your little one to the optometrist can be tricky. Here’s a friendly guide to help you navigate those important eye health milestones.
The First Eye Exam: The Earlier, The Better!
Did you know that the New Zealand Association of Optometrists (NZAO) recommends that children have their first eye exam between 6 and 12 months old, and then again at 3 and 5 years old? It may seem early, but catching any potential issues while they’re young can make a world of difference. If your child hasn’t had their first check-up yet, don’t worry—there’s still time!
Key Ages for Eye Exams
6 Months: The first exam, just to ensure everything is developing normally.
3 Years: A crucial time to check for vision problems as your child starts preschool.
5 Years: Before they enter kindergarten, it's essential to ensure they’re ready for school.
Signs It’s Time for a Check-Up
Even outside these recommended ages, keep an eye out for certain signs that may indicate it’s time to schedule an appointment:
Squinting or Covering One Eye: This could be a sign of vision issues.
Frequent Eye Rubbing: If your child is constantly rubbing their eyes, they might be experiencing discomfort or strain.
Complaints About Blurry Vision: If your child mentions that things look fuzzy, it’s time for a check-up.
Poor concentration or sluggish academic performance: If you have concerns about your child's performance at school, consider getting an eye exam to rule out vision issues.
The Importance of Regular Check-Ups
Just like regular pediatric check-ups, eye exams should be a part of your child’s health routine. Regular visits can help identify issues like nearsightedness, farsightedness, or even more serious conditions that could affect their overall development and learning.
What to Expect During the Visit
Bringing your child to the optometrist doesn’t have to be a daunting experience! Our team is trained to make the process fun and engaging. Here’s a quick overview of what you can expect:
Friendly Environment: Our office is designed to be welcoming for children.
