How To Choose Sunglasses: A Guide To Lenses

Sunglasses are ubiquitous tokens of style, but to protect your eyes, they’re also necessary. If you try to choose the perfect pair of sunglasses for you, it helps to consider what to look for when you browse, other than the shades that aesthetically express the real you. Good looks are important, but there’s more to know about them. When picking the right sunglasses, there are many different construction configurations to remember, each having specific advantages worth weighing before you purchase. However, we can overlook aesthetics, but we’ll help you pick sunglasses according to your style and with the right lens.


Sunglasses Styles

Casual sunglasses: Casual sunglasses do an outstanding job of shielding your eyes from the sun as you drive to work and stroll around town, suitable for daily use and simple leisure activities. Casual sunglasses are usually not meant to handle the power of action sports.

Sport sunglasses: Sport sunglasses are designed for sports such as biking, climbing, and cycling and provide a lightweight and a perfect look for fast-paced adventures. High-end fabrics for frames and lenses are more resistant to impact and lightweight than casual sunglasses. Grippy nose pads and temple ends are often usually used in Sport sunglasses, a design that helps keep the lenses in place even though you are sweating. Some sports sunglasses have removable lenses such that various light conditions can be changed.

Glacier glasses: Glacier glasses are unique lenses specially designed to shield the eyes from high altitudes with bright light and sunshine reflected off the snow. They also have wrap-around extensions to keep light from touching the edges.

Features Of Sunglass Lens

Polarized lenses: Polarized lenses minimize glare significantly. If you like watersports or are incredibly vulnerable to sunlight, polarization is a beautiful feature.

Polarized lenses react with the tints on windshields in some instances, causing blind spots and decreasing the illumination of LCD readings. Consider mirrored lenses as a glare-reducing solution if this happens.

Photochromic lenses: Photochromic lenses respond dynamically to the changing strength and conditions of light. On sunny days, these lenses get darker and lighter as temperatures get darker.

A few caveats: It takes longer for the photochromic method to operate in cold weather, and it doesn’t work at all when driving a vehicle, so UVB rays do not penetrate the windshield.

Interchangeable lenses: Certain types of sunglasses come in various shades with interchangeable (removable) lenses. These multi-lens systems help you to adapt the safety of your eyes to your operations and conditions. If you need consistent results in a wide range of circumstances, consider this alternative.

Lens Materials For Sunglasses

  • Optical Glass Sunglasses Lenses

To guarantee distortion-free vision, optical glass lenses are ground and polished to exacting specifications. Optical glass is highly durable and resistant to cracks. High levels of distortion-free vision and scratch-resistance are the significant benefits of optical glass lenses. However, the downside is that they appear to be more costly and often spider or crack, which may threaten physical sports when afflicted.

  • Polycarbonate Sunglasses Lenses

For people who would be moving ‘and shaking’ in their sunglasses, Polycarbonate plastic lenses are the safest bet. Lenses made of polycarbonate are made of a substance identical to those of aircraft windshields and are nearly indestructible. Polycarbonate is lightweight and scratch-resistant, has a high degree of optical transparency, and is 50 times more damage resistant than optical glass, which makes it an excellent lens distortion-free. A marginally lesser degree of scratch resistance and optical transparency that is not as strong as optical glass or NXTT are the only drawbacks.

  • NXT Polyurethane Sunglasses Lenses

This content for the lens is top of the line. It incorporates all the advantages of optical glass with all the durability strengths of polycarbonates. NXT Polyurethane lenses are the perfect option for anyone willing to fork out the cash to get them. Trivex, an advanced polymer material whose benefits include extreme impact tolerance, superior optical clarity, and ultralight weight, is manufactured with NXT lenses.

  • Acrylic Sunglasses Lenses

The go-to for a cheap sunglass solution is acrylic lenses, and an excellent option for casual or fashion sunglasses. These maintain much of the longevity and optical consistency with minor compromises of top-shelf possibilities without the hefty price tag.

Sunglass Lens Coatings

The more expensive the sunglasses are, the more likely they are to have several coating layers. This may include a water-repellent hydrophobic coating, an anti-scratch coating to maximize longevity, and an anti-fog coating for damp environments or high-energy operations.

Mirrored or flash coating refers to a translucent film applied to each of the sunglass lenses’ exterior surfaces. By absorbing most of the light entering the lens surface, they minimize glare. Mirrored coatings render products look darker than they are, but softer tints are also used to compensate for this.
