Different Types of Lenses Explained for Sunglasses

Sunglasses are a staple accessory, especially during the summer months. Not only do they add a touch of style to your outfit, but they also serve a vital purpose in protecting your eyes from the harmful effects of the sun's rays. However, with the multitude of options available in the market, it can be overwhelming to choose the right pair of sunglasses. Understanding the different types of lenses is crucial in making an informed decision. In this article, we will explore the various types of lenses for sunglasses and their unique features.

Why Sunglasses Are So Important In Summer?

Before diving into the different lens options, let's first understand why sunglasses are essential, particularly during the summer season. The sun emits ultraviolet (UV) rays, including UVA and UVB, which can be harmful to our eyes. Prolonged exposure to these rays can lead to various eye conditions such as cataracts, macular degeneration, and photokeratitis. Wearing sunglasses with appropriate lenses can significantly reduce the amount of UV radiation that reaches our eyes, protecting them from potential damage.

Detailed Introduction to Different Types of Lenses


Different lens colors serve various purposes and offer specific benefits. Here are some common lens colors and their characteristics:

Grey: Most of the sunglasses are with grey lenses. They provide true color perception and are suitable for everyday use. The color grey reduces brightness and glare without distorting colors, making them a popular choice for many.

Yellow: Yellow lenses enhance contrast and depth perception, making them ideal for activities such as driving and sports. They are especially beneficial in low-light conditions.


Green: Green lenses provide excellent color contrast and visual clarity. They enhance natural colors while reducing glare, making them a versatile option for various outdoor activities.

Blue: Blue lenses are primarily chosen for their aesthetic appeal. They offer slight color distortion but effectively reduce glare. Blue lenses are commonly used for fashion purposes.

Purple: Purple lenses offer enhanced color perception and contrast. They are often preferred for activities like skiing or snowboarding, as they can improve visibility in snowy conditions.


In addition to lens colors, various coatings can be applied to sunglasses to enhance their performance and durability. Some common lens coatings include:

Mirrored: Mirrored coatings provide a reflective surface on the outside of the lenses, reducing the amount of light that enters your eyes. They are particularly useful in intense sunlight conditions and are popular among athletes and outdoor enthusiasts.

Polarized: Polarized lenses reduce glare caused by reflections from flat surfaces such as water, snow, and glass. They enhance visual clarity, reduce eye strain, and are highly recommended for activities near water or snow.

Anti-fog: Anti-fog coatings prevent the lenses from fogging up in humid or cold environments. This feature is particularly useful for individuals engaged in activities that generate perspiration, such as running or cycling.

Anti-flare: Anti-flare coatings minimize the reflection of light off the back surface of the lenses. They help reduce eye strain and improve overall visual comfort, especially when facing bright light sources.

Can Sunglasses be customized to prescription ones?

Yes, sunglasses can be customized to prescription lenses. Individuals who require corrective vision can opt for prescription sunglasses, ensuring both eye protection and clear vision. Consulting with an optometrist or eyewear specialist will help you find the right sunglasses that cater to your specific prescription needs.

Things You Must Know about Wearing Sunglasses

While sunglasses offer protection and style, there are a few essential points to keep in mind:

UV Protection: Ensure that your sunglasses provide 100% UV protection. Look for labels or tags that indicate their ability to block both UVA and UVB rays.

Fit and Coverage: Select sunglasses that fit comfortably and provide adequate coverage. Properly fitted sunglasses prevent UV rays from entering through the sides, top, or bottom of the frames.

Quality: Invest in sunglasses from reputable brands known for their quality and optical standards. High-quality lenses offer better visual clarity, durability, and protection.

Maintenance: Proper maintenance is crucial to prolonging the lifespan of your sunglasses. Use a microfiber cloth to clean the lenses and store them in a protective case when not in use.


Choosing the right pair of sunglasses involves understanding the different types of lenses available in the market. Whether you opt for grey, yellow, green, blue, or purple lenses, each color provides unique benefits. Additionally, lens coatings can enhance the performance and durability of your sunglasses. By considering these factors, you can confidently select sunglasses that not only complement your style but also safeguard your precious eyes.
