Types of Sunglasses: Complete Buying Guide for Beginners
Walking into a sunglasses store can feel overwhelming. Rows of different shapes, sizes, and styles stare back at you, each promising to be “the one.” But here’s the truth: not all sunglasses are created equal, and the type you choose can make or break your comfort, style, and eye protection.
Whether you’re squinting through your morning commute, hitting the beach, or just want to look effortlessly cool, understanding the different types of sunglasses will help you make the right choice. By the end of this guide, you’ll know exactly which style suits your needs, activities, and personal taste.

Understanding Sunglasses Basics
Before going into specific types, let’s clear up what actually makes sunglasses different from regular eyewear. The primary job of sunglasses is blocking harmful UV rays, specifically UV-A and UV-B radiation that can damage your eyes over time. Quality sunglasses block 99-100% of these rays, regardless of how dark the lenses appear.
Why sunglasses type matters more than brand: A $20 pair of sunglasses with the right shape and UV protection will serve you better than $200 designer frames that don’t fit your face or lifestyle. Smart shoppers focus on type first, then find quality brands within that category.
Types of Sunglasses by Lens Shape
1. Aviator Sunglasses
Aviator sunglasses were born out of necessity. In the 1930s, U.S. military pilots required eyewear that could reduce intense sunlight and glare at high altitudes while offering a wide field of vision. The signature teardrop shape was designed to cover more of the eye area than most other styles, making aviators a functional choice for anyone who spends significant time outdoors.
The classic aviator works best on people with:
- Square or rectangular faces (the curves soften angular features)
- Heart-shaped faces (the wider bottom balances a broader forehead)
- Larger facial features (small aviators can look disproportionate)
Modern aviator variations include the Ray-Ban Aviator Classic, which maintains the original proportions, and the Oakley Crosshair Aviator, which adds contemporary lens technology. For budget-conscious buyers, the Livho Classic Aviator offers a similar style at a fraction of the cost.
Aviators don’t work well on round faces because they emphasize the circular shape rather than adding definition. They’re also not ideal for very small faces, as the large lens area can overwhelm delicate features.
2. Wayfarer Sunglasses
Wayfarer sunglasses revolutionized eyewear when they debuted in the 1950s. Their thick plastic frames and rectangular shape introduced a casual-yet-sophisticated style that suits nearly any setting. This versatility has made Wayfarers one of the most enduring and popular types of sunglasses today.
The beauty of wayfarers lies in their universal appeal. They work on most face shapes because the rectangular frame adds structure without being too geometric. The thick frame also provides excellent durability – these sunglasses can handle daily wear and occasional drops.
Size variations matter: Standard wayfarers suit most people, but oversized versions work better for larger faces or those who want maximum sun protection. The Ray-Ban Original Wayfarer remains the gold standard, while the PolarSpex Polarized offers a similar style at a lower price point.
Wayfarers transition seamlessly from beach days to business casual settings. Pair them with a t-shirt and jeans for weekend errands, or wear them with a button-down shirt for a polished casual look.
3. Round Sunglasses
Round sunglasses experienced a major comeback in recent years, driven partly by vintage fashion trends and celebrity endorsements. The circular shape creates a softer, more artistic appearance compared to angular frames.
These work exceptionally well on people with:
- Square or rectangular faces (the curves balance sharp angles)
- Heart-shaped faces (the round bottom adds weight to the lower face)
- Those with angular features who want to soften their appearance
Size considerations: Small round frames create a subtle, intellectual look, while oversized versions make a bold fashion statement. The Ray-Ban Round Classic offers timeless appeal, while the Htms Retro Round provides trendy style at a budget-friendly price.
Round sunglasses don’t flatter round faces because they emphasize the circular shape. They also require confidence to wear – the distinctive shape draws attention and makes a statement.
4. Cat-Eye Sunglasses
Cat-eye sunglasses feature an upswept outer edge that mimics the shape of a cat’s eye. This vintage-inspired style peaked in popularity during the 1950s and 1960s but has remained a feminine favorite for its flattering, face-lifting silhouette.
The upward angle of cat-eye frames creates the illusion of higher cheekbones and a more defined jawline. This makes them particularly flattering for:
- Round faces (the angular shape adds definition)
- Square faces (softer cat-eye versions balance angular features)
- Those who want to appear more youthful or glamorous
Variation spectrum: Subtle cat-eye frames work in professional settings, while dramatic versions suit special occasions or fashion-forward individuals. The Versace Cat-Eye sunglasses represents luxury in this category, while the Guess Retro-inspired Cat-Eye sunglasses offers accessible style.
Cat-eye sunglasses can overwhelm small faces or clash with very casual outfits. They’re also less suitable for active pursuits due to their typically delicate construction.
5. Square and Rectangular Sunglasses
Square and rectangular sunglasses feature straight lines and defined angles. This geometric approach creates a modern, structured appearance that conveys confidence and professionalism.
These angular frames work best for:
- Round faces (the straight lines add definition and structure)
- Oval faces (most shapes work, but squares add interesting contrast)
- Professional settings where you want to appear authoritative
Sport vs. fashion applications: Athletic frames like the Oakley Holbrook focus on durability and performance, while fashion frames like the Gucci Rectangular sunglasses prioritize style. Budget options, such as the ZENOTTIC Polarized Square sunglasses, offer functionality without the premium price.
The key to wearing square sunglasses successfully is getting the proportions right. The frame should be roughly the same width as your face, and the height should balance your facial features without overwhelming them.
6. Oversized Sunglasses
Oversized sunglasses provide maximum coverage and UV protection while making a bold fashion statement. Popularized in the 1970s, they continue to offer practical benefits beyond their glamorous appearance, especially for shielding the delicate skin around the eyes.
Practical advantages include:
- Maximum UV protection for the eye area and surrounding skin
- Better coverage for those with larger faces
- Effective glare reduction due to a larger lens area
- Instant glamour factor
The Burberry Oversized sunglasses represent premium options, while the Bolon Oversized Fashion Sunglasses provide similar coverage at a lower cost.
When bigger isn’t better: Oversized frames can slip down the nose more easily, may cause pressure points behind the ears, and can look disproportionate on very small faces. They’re also less practical for active pursuits.
Types of Sunglasses by Frame Material
1. Plastic Frames
Plastic frames dominate the sunglasses market due to their versatility and affordability. Modern plastic construction uses materials like acetate, which offers excellent durability and color options.
Benefits of plastic construction:
- Lightweight and comfortable for extended wear
- Available in virtually any color or pattern
- Less likely to conduct heat in sunny conditions
- Generally more affordable than metal alternatives
Plastic frames require minimal maintenance but can become brittle over time, especially if left in hot cars. They’re also harder to adjust for fit compared to metal frames.
Quality indicators: Look for thick, substantial plastic that doesn’t feel flimsy. Higher-end plastic frames often use acetate, which feels heavier and more substantial than cheap plastic.
2. Metal Frames
Metal frames offer durability and adjustability that plastic cannot match. Common metals include stainless steel, titanium, and aluminum alloys, each with distinct characteristics.
Advantages of metal construction:
- Superior durability and longevity
- Adjustable nose pads and temple arms for a custom fit
- Thinner profile for a more sophisticated appearance
- Corrosion resistance (in quality metals)
Metal frames typically cost more than plastic but justify the investment through longevity. They’re also easier to repair if damaged.
Material considerations: Titanium offers the best strength-to-weight ratio but costs more. Stainless steel provides good durability at a moderate price. Avoid cheap metal frames that may contain nickel, which can cause allergic reactions.
3. Composite Materials
Modern composite materials combine the best aspects of plastic and metal. These advanced materials appear in high-performance sunglasses designed for specific activities.
Performance benefits:
- Excellent impact resistance
- Lightweight despite durability
- Flexible frames that return to shape after bending
- Often hypoallergenic
Composite frames typically cost more than basic plastic or metal but offer superior performance for active lifestyles. Brands like Oakley and Nike frequently use proprietary composite materials in their sports-focused designs.
Types of Sunglasses by Activity and Lifestyle
1. Sports Sunglasses
Sports sunglasses prioritize performance over fashion. They feature wraparound designs for peripheral vision protection, secure fits that stay in place during activity, and specialized lens technologies.
Key performance features:
- Wraparound design prevents side glare
- Secure grip points to prevent slipping
- Impact-resistant lens materials
- Ventilation to prevent fogging
The Oakley Flak 2.0 XL represents the gold standard for sports sunglasses, while the Tifosi Slip offers similar functionality at a more affordable price point.
Sport-specific considerations: Cycling requires aerodynamic frames and clear peripheral vision. Running demands lightweight, secure-fitting designs. Water sports benefit from polarized lenses and floating frames.
2. Driving Sunglasses
Driving sunglasses focus on reducing glare and enhancing visual contrast for safer driving. They typically feature polarized lenses and frames designed for comfortable extended wear.
Driving-specific benefits:
- Polarized lenses reduce glare from wet roads and other vehicles
- Enhanced contrast helps distinguish objects in varying light conditions
- Comfortable fit for long drives
- Quick on/off capability for tunnels and changing conditions
The Maui Jim Cliff House and Ray-Ban Predator 2 excel for driving, while the Duduma Polarized Sports offer budget-friendly driving performance.
Color considerations: Brown and amber lenses enhance contrast, while gray lenses provide true color perception. Avoid very dark lenses that may impair vision in tunnels or shaded areas.

3. Fashion Sunglasses
Fashion sunglasses prioritize style and trend-following over technical performance. They’re designed to complement outfits and personal style rather than excel in specific activities.
Style versatility: Fashion sunglasses should work with multiple outfits and occasions. Classic shapes like wayfarers and aviators offer the most versatility, while trendy designs make stronger statements but may date quickly.
Investment strategy: Consider building a small collection with different styles for different occasions rather than buying one expensive pair. A classic pair for daily wear, a trendy pair for special occasions, and a sport-specific pair for active pursuits cover most needs.
4. Outdoor Adventure Sunglasses
Outdoor adventure sunglasses handle extreme conditions and demanding activities. They feature rugged construction, specialized lens technologies, and practical design elements.
Extreme condition features:
- High-altitude UV protection
- Impact resistance for rough activities
- Secure retention systems
- Fog-resistant treatments
The Julbo Vermont Classic serves mountaineers and glacier travelers, while the Oakley Turbine works for general outdoor activities.
Practical accessories: Consider sunglasses with retention straps, protective cases, and lens cleaning cloths. These additions become essential during extended outdoor activities.
How to Choose the Right Type of Sunglasses
Budget Considerations
Sunglasses span a huge price range, from $20 gas station pairs to $200+ designer frames. Understanding what you get at different price points helps you make smart purchasing decisions.
$10-30 range: Basic UV protection and simple construction. Good for occasional use or high-loss activities like beach days.
$30-100 range: Better construction, improved optical quality, and often polarized lenses. Suitable for regular use and most activities.
$100-200 range: Premium materials, advanced lens technologies, and better durability. Worth the investment for daily wear.
$200+ range: Designer styling, luxury materials, and brand prestige. The performance gains may not justify the cost for most users.
Quality Indicators
Frame construction: Quality frames feel substantial without being heavy. Check that hinges move smoothly and temple arms maintain their shape. Avoid frames that feel flimsy or have obvious construction flaws.
Lens quality: Good lenses provide clear, undistorted vision. Look through the lenses and check for optical distortion, color shifts, or visible imperfections. Polarized lenses should eliminate glare when tested against reflective surfaces.
Hardware details: Quality sunglasses feature smooth hinges, secure screws, and well-finished edges. Cheap construction often shows in these details.
Sizing and Fit
Measurement guide: Sunglasses dimensions include lens width, bridge width, and temple length. These measurements help ensure proper fit when buying online.
Comfort factors: Properly fitted sunglasses should stay in place without pinching or sliding. The frames should sit comfortably on your nose and ears without creating pressure points.
Adjustment possibilities: Metal frames offer more adjustment options than plastic. Consider this if you have specific fit requirements or want to fine-tune the comfort.
Making Your Decision
Choosing the right type of sunglasses depends on balancing your style preferences, practical needs, and budget. Start by identifying your primary use case – daily wear, specific activities, or fashion statements.
Consider building a small collection with essential sunglasses rather than searching for one perfect pair. A classic everyday pair, a sport-specific option, and a fashion-forward choice cover most situations without breaking the budget.
Choose a style that feels comfortable, looks good on your face, and matches your lifestyle. With the right type of sunglasses, you’ll protect your eyes while looking great – and that’s a combination worth investing in.
