Sunglasses Selection Guide: 5 Key Directions to Help You Choose!

Whether it's observing celebrities' airport fashion or following the style guides of internet trendsetters, sunglasses are always an essential accessory to enhance an overall look! If you want to own a stylish and trendy pair of sunglasses but don't know how to choose, then this article is perfect for you! In this article, we will share five key directions to help you choose sunglasses that not only look good but also serve their purpose.

Wearing sunglasses offers numerous advantages, such as filtering excessive glare, protecting against the harmful wavelengths of ultraviolet radiation, and shielding against airborne particles. Moreover, by choosing the right frame, sunglasses can also effectively enhance your facial features and complement your overall style. Let's explore the five key benefits of wearing sunglasses!

Filtering Polarized Light

Polarization refers to the phenomenon when light rays strike a flat surface and reflect off, creating intense and blinding glare. This glare can come from various sources, including overhead light sources and direct sunlight. At times, it can even come from the ground or surrounding surfaces, causing discomfort and potentially leading to feelings of dizziness and eye strain. Sunglasses are effective in filtering out polarized light, reducing the impact of intense glare and providing protection for your eyes.

Combatting Ultraviolet (UV) Radiation

UV radiation, often mentioned in the context of sun exposure, poses various risks to your eyes. Prolonged exposure to UV radiation can accelerate skin aging and harm your eyes. It has been linked to conditions such as macular degeneration, cataracts, and pterygium. Sunglasses equipped with UV protection act as a shield, safeguarding your eyes from the harmful effects of UV radiation. UV radiation comes in two main forms:


UVA refers to ultraviolet A radiation, which has good penetration capabilities and can lead to skin tanning. Prolonged exposure of the eyes to UVA can increase the risk of conditions such as malignant eyelid tumors and photokeratitis.


UVB, although less penetrating than UVA, has higher energy levels and is more likely to contribute to skin aging. Additionally, UVB is absorbed by the cornea, and prolonged exposure to UVB-containing light may result in conditions such as cataracts, keratitis, and retinal damage.

Filtering Airborne Particulate Matter

In recent years, environmental pollution has become a pressing issue, especially air pollution. Apart from affecting lung function in humans, airborne particulate matter in the air can also lead to eye allergies. In severe cases, it may cause eye inflammation. During such situations, choosing to wear sunglasses can effectively block these airborne particles, promoting eye health.

Effective Facial Contour Enhancement

Sunglasses not only protect your eyes but also have a great impact on enhancing your facial features when you choose the right frame proportions and frame shape. Sunglasses can conceal wide cheekbones, creating the illusion of a smaller face and making your facial features appear more three-dimensional. It's like achieving a celebrity-like, high-end look without the need for plastic surgery.

Adding Style to Your Outfits

Often feel like your outfits lack a certain flair? Well, sunglasses can help you elevate your fashion game and add depth to your attire. By carefully selecting sunglasses and complementing them with items like necklaces and bracelets, you not only enhance the details of your outfit but also exude a unique sense of style and charm.

How to Choose the Right Sunglasses? Wearing sunglasses offers numerous benefits, not only elevating your style but also providing protection for your eyes. But what should you consider when selecting sunglasses to ensure they are a perfect fit for you? Below, we share five key factors to help you effortlessly find the sunglasses that best complement your individual style!

Lens Color

As mentioned earlier, sunglasses are effective at filtering polarized light. However, if you choose the wrong lens color, it might not effectively block intense light, leading to discomfort. We recommend selecting lens colors such as gray, brown, or green. Gray and green lenses evenly absorb the color spectrum without altering the original colors of objects. Brown lenses are excellent at filtering out blue light and blocking reflective rays. Additionally, yellow lenses are a good choice for their strong ability to block harmful blue light, making them suitable for night driving to reduce glare. Among the various lens colors, we advise against opting for blue lenses as they tend to attract more harmful blue light, potentially causing macular degeneration over time.

Scratch-Resistant Coating

While it's true that no sunglasses lens is entirely scratch-proof, it's advisable to handle them with care. Common situations that can lead to lens scratches include wiping them with tissues that contain lint or debris after cleaning. By choosing sunglasses with a scratch-resistant coating, you can reduce the likelihood of minor scratches that may develop during regular use. This not only enhances the durability of your sunglasses but also helps maintain clear vision.

UVA and UVB Resistance

As mentioned earlier, both UVA and UVB rays can potentially harm your eyes when exposed over time. Therefore, when choosing the right sunglasses, it's essential to pay special attention to whether they offer protection against UVA and UVB. Without adequate UV protection, your pupils will naturally dilate when you wear sunglasses, potentially causing more significant harm. It's crucial to select sunglasses that clearly indicate their ability to resist UVA and UVB rays to ensure your eyes are adequately shielded.

Purchase Sunglasses Tested for Quality Sunglasses undergo rigorous quality testing to assess various factors, including light transmittance, uniformity of light, polarization efficiency, lens quality, and more. These filters are typically classified into five levels, each affecting the amount of light that can pass through the lenses. Additionally, optical quality is categorized into two levels, although distinguishing between them may require specialized equipment. To ensure you're getting high-quality sunglasses, we recommend choosing ones that have passed the testing, indicating that they meet stringent quality standards.

By considering these five key factors when selecting sunglasses, you can make an informed choice that not only enhances your style but also provides optimal protection and comfort for your eyes.

Choosing Sunglasses According to Face Shape

How can you pick the right sunglasses?

In addition to the protective features mentioned earlier, it's essential to consider your face shape when making your selection. Since everyone's face shape varies, suitable frames will also differ. Below, we provide a table to help you easily understand how to choose:

By matching your sunglasses to your face shape, you can enhance your appearance while ensuring a comfortable and stylish fit.

What's the Difference Between Generic and Branded Sunglasses?

There are various sunglasses available in the market, ranging from budget-friendly generic options to high-end branded ones that can cost thousands of pounds. So, what sets these two categories apart? The primary distinctions lie in their ability to protect against ultraviolet (UV) radiation and whether they meet optical standards. However, purchasing sunglasses doesn't necessarily require you to invest in luxury brands. As long as you ensure the lenses provide UV protection, meet optical standards, and the frames fit comfortably, it's highly recommended to make the purchase!

Generic Sunglasses:

  • Generic sunglasses refer to those priced below a certain threshold, often found at flea markets, roadside stalls.
  • While these products may indicate a level of sun protection, they often lack professional quality control to guarantee their effectiveness against UVA and UVB rays.
  • In terms of design, generic sunglasses tend to prioritize aesthetics, which can result in discomfort during prolonged wear. They may press against the nose bridge or cause discomfort around the ears.
  • It's advisable to reserve generic sunglasses for short outings or purely for enhancing your style.

Branded Sunglasses:

  • Branded sunglasses, on the other hand, prioritize various factors when designing their products, including customer comfort, the ability to block intense light, and protection against UVA and UVB rays.
  • These sunglasses combine functionality with fashion, ensuring that customers have a comprehensive eyewear experience.
  • For example, our Georgia series features sleek traveler frames that effectively complement facial contours. Additionally, the lenses are equipped with UVA and UVB protection, allowing for extended and comfortable wear while maintaining a stylish appearance.
