Why This Guide Matters
Choosing sunglasses isn't just about style - it's about protecting your eyes from Australia's harsh UV rays while ensuring comfort and performance. With so many options available, it's easy to get overwhelmed or make expensive mistakes.
We've tested dozens of sunglasses across different price points and categories. This guide will help you understand what features actually matter, what you can skip, and how to find the perfect pair for your needs and budget.
UV Protection: The Non-Negotiable Feature
Let's start with the most important factor - UV protection. In Australia, this isn't optional. Our UV levels are among the highest in the world, and inadequate protection can lead to serious eye problems.
Understanding UV Ratings
Look for sunglasses that block 100% of UVA and UVB rays. This is often labeled as "UV400" protection. Anything less isn't worth your money, regardless of how stylish the sunglasses look.
Category Ratings Explained
- Category 0: Very light tint (0-20% VLT) - Fashion only, minimal sun protection
- Category 1: Light tint (20-57% VLT) - Low sun intensity
- Category 2: Medium tint (57-82% VLT) - Medium sun intensity
- Category 3: Dark tint (82-92% VLT) - Strong sun intensity - Most common for Australian conditions
- Category 4: Very dark tint (92-97% VLT) - Extreme sun conditions
For most Australian conditions, Category 3 lenses provide the best balance of protection and visibility. Category 4 lenses are too dark for driving and should only be used for specific activities like high-altitude mountaineering.
Lens Materials: What You Need to Know
The material your lenses are made from affects everything - clarity, durability, weight, and price. Here's what each option offers:
Polycarbonate Lenses
These are impact-resistant and lightweight, making them popular for sports and active use. They're also affordable, which is why you'll find them in most mid-range sunglasses. The downside? They can scratch more easily than other materials.
Nylon Polyamide Lenses
This is what VALLON uses in their V52® technology. It offers excellent optical clarity, impact resistance, and is lighter than polycarbonate. It's more expensive but provides superior performance.
Glass Lenses
Glass offers the best optical clarity and scratch resistance, but it's heavier and can shatter on impact. It's also more expensive and less common in modern sunglasses.
CR-39 Plastic
This material offers good optical clarity and is lighter than glass, but it's not as impact-resistant as polycarbonate or nylon.
Lens Colors and Tints: More Than Just Style
Different lens colors aren't just about aesthetics - they affect how you see the world and perform in different conditions.
Gray Lenses
These provide true color perception and reduce brightness without distorting colors. They're excellent for general use and driving.
Brown/Amber Lenses
These enhance contrast and depth perception, making them ideal for low-light conditions or activities requiring good depth perception like golf or fishing.
Green Lenses
Similar to gray lenses but with slightly better contrast. They're good for general outdoor activities and provide comfortable vision.
Blue Lenses
These can enhance contrast in certain conditions but may distort colors. They're less common and not recommended for driving.
Yellow Lenses
These enhance contrast in low-light conditions but aren't suitable for bright sun. They're popular for shooting sports and low-light activities.
Polarized Lenses: Worth the Extra Cost?
Polarized lenses reduce glare from reflective surfaces like water, snow, and roads. In Australia, this can be particularly valuable for water activities and driving.
When Polarization Helps
- Water sports (fishing, kayaking, sailing)
- Driving on wet roads
- Snow activities
- Beach activities
- Any activity with reflective surfaces
When Polarization Can Be Problematic
- Using digital devices (can cause screen visibility issues)
- Flying (can interfere with instrument readings)
- Some LCD screens may appear darker or distorted
For most people, polarized lenses are worth the extra cost, especially in Australia's bright conditions. Just be aware of the potential issues with digital devices.
Frame Materials: Finding the Right Balance
The frame material affects comfort, durability, and style. Here's what each option offers:
Acetate Frames
These are made from plant-based materials and offer excellent durability and comfort. They're hypoallergenic and can be molded into various shapes and colors. Premium acetate frames feel solid and well-constructed.
Metal Frames
Usually made from titanium, stainless steel, or aluminum. They're lightweight and durable but can feel cold in winter and may cause allergic reactions in some people.
Nylon Frames
These are lightweight and flexible, making them popular for sports sunglasses. They're impact-resistant but may not feel as premium as acetate or metal.
TR-90 Frames
This is a type of nylon that's particularly flexible and lightweight. It's popular in sports sunglasses and offers good durability.
Frame Styles: Finding Your Perfect Shape
Frame style affects both aesthetics and functionality. Here's how different shapes work for different face types and activities:
Aviator Style
Classic teardrop shape that works for most face types. They provide good coverage and have a timeless appeal. Perfect for both casual and professional settings.
Wayfarer Style
Rectangular frames that offer good coverage and a classic look. They work well for square and oval face shapes.
Round Frames
These work well for square faces and offer a vintage aesthetic. They may not provide as much coverage as other styles.
Wraparound Style
These provide maximum coverage and protection, making them ideal for sports and outdoor activities. They may not be suitable for professional settings.
Cat-Eye Style
These offer a retro aesthetic and work well for heart-shaped faces. They're more fashion-focused than performance-oriented.
Fit and Comfort: Getting It Right
Even the best sunglasses won't work if they don't fit properly. Here's what to look for:
Nose Bridge Fit
The sunglasses should sit comfortably on your nose without pinching or sliding. Adjustable nose pads can help achieve the perfect fit.
Temple Pressure
The temples should apply gentle pressure behind your ears without causing discomfort. They shouldn't be so tight that they cause headaches.
Coverage
The lenses should provide adequate coverage without obstructing your peripheral vision. For maximum protection, look for frames that wrap around your face slightly.
Weight Distribution
The sunglasses should feel balanced on your face. Heavy frames can cause discomfort during extended wear.
Adjustability
Features like adjustable temple ends (like those in VALLON's Howlin' sunglasses) allow for custom fitting, which can make a big difference in comfort.
Activity-Specific Considerations
Different activities have different requirements. Here's what to consider for common Australian activities:
Driving
Choose Category 3 lenses with good peripheral vision. Avoid Category 4 lenses as they're too dark for safe driving. Polarized lenses can help reduce glare from wet roads.
Water Sports
Look for sunglasses with secure fit features like headstraps or grippy nose pads. Polarized lenses are particularly valuable for water activities.
Hiking and Outdoor Activities
Choose sunglasses with good coverage and secure fit. Consider features like headstraps for active pursuits. Impact resistance is important for outdoor activities.
Beach Activities
Look for sunglasses with good coverage to protect against sand and wind. Polarized lenses help reduce glare from water and sand.
Professional Use
Choose classic styles that work in professional settings. Avoid overly sporty designs unless your workplace is casual.
Budget Considerations: Getting Value for Money
Sunglasses range from $20 to $500+, so understanding what you're paying for is crucial.
Under $50
At this price point, focus on UV protection and basic durability. Don't expect premium materials or advanced features. These are suitable for occasional use.
$50-$150
This range offers better build quality and materials. You'll find decent polycarbonate lenses and more durable frames. Good for regular use.
$150-$300
This is where you'll find premium materials like acetate frames and advanced lens technologies. These sunglasses should last years with proper care.
$300+
At this level, you're paying for premium materials, advanced technologies, and brand prestige. The performance improvements may be marginal compared to the $150-$300 range.
Value Considerations
Consider cost per use rather than just upfront cost. A $200 pair that lasts 5 years is better value than a $50 pair that needs replacing every year.
Common Mistakes to Avoid
We've seen plenty of people make expensive mistakes when buying sunglasses. Here's how to avoid them:
Prioritizing Style Over Protection
Don't sacrifice UV protection for style. No matter how good sunglasses look, they're useless if they don't protect your eyes properly.
Ignoring Fit
Even expensive sunglasses won't work if they don't fit properly. Always try them on before buying, or ensure you can return them if buying online.
Buying Based on Price Alone
Cheap sunglasses often cost more in the long run due to poor durability. Expensive sunglasses aren't always better, but very cheap ones usually are poor quality.
Not Considering Your Activities
Think about how you'll use the sunglasses. Fashion sunglasses won't work for sports, and sport sunglasses might not be appropriate for professional settings.
Ignoring Lens Quality
Poor quality lenses can cause eye strain and headaches. Look for lenses with good optical clarity, not just UV protection.
Maintenance and Care: Making Them Last
Proper care can extend the life of your sunglasses significantly. Here's how to keep them in top condition:
Cleaning
Use a microfiber cloth and lens cleaner designed for sunglasses. Avoid using clothing or paper towels, which can scratch the lenses.
Storage
Store sunglasses in their case when not in use. Don't leave them in hot cars or exposed to direct sunlight for extended periods.
Handling
Always use both hands when putting on or taking off sunglasses. Using one hand can bend the frames over time.
Regular Maintenance
Check screws and hinges periodically. Tighten loose screws to prevent further damage.
Professional Service
For expensive sunglasses, consider professional cleaning and adjustment services. Many manufacturers offer lifetime warranties that include maintenance.
