When selecting eyeglasses, it is essential to take into account the material which best meets your prescription and frame style. Lenses come in a range of materials such as plastic, glass and polycarbonate.
Plastic lenses are lightweight and cost-effective, but they may scratch easily. For a more robust option, consider polycarbonate lenses which offer better impact resistance.
“Classic Cool: Aviator Shades”
If you’re channeling your inner Tom Cruise or simply wanting to add a stylish flair, aviator sunglasses are the ideal choice. Not only are they timeless and functional, but come in an array of styles so they’ll go with virtually any outfit.
Bausch & Lomb originally developed these eyewear styles for military pilots to provide optimal sun protection and visibility while flying at high altitudes. Their large teardrop-shaped lenses shielded pilots from both direct sunlight and subzero temperatures that could cause condensation on goggles.
They featured a prominent rubberized brow bar to prevent sweat from getting into the eyes during hot, sweltering cockpits. Soon enough, these became standard issue for U.S. fighter pilots and eventually adopted by civilians as well.
Aviator glasses have always been a timeless classic, and this pair is no exception. Featuring gold frames and green lenses, they offer the classic colorway of this style while being polarized to reduce glare.
They come in a range of sizes, from Medium (58mm) to Large (62mm), so you can find the ideal fit for your face shape. Plus, these lenses are scratch-resistant and offer 100% UV protection – meaning you can wear them wherever life takes you without fear for your eyesight.
Eyeglasses Online: Finding the Perfect Pair for You
Glasses have evolved beyond just being a way to correct your vision; they’ve become an accessory that lets you express yourself with unique frames and styles. From vintage looks and patterned frames to combining both, the choice is yours when it comes to selecting the perfect pair!
When searching for the ideal pair of glasses, it’s essential to identify your requirements and which lenses will provide the most benefit. Consider what materials are available and their advantages, as well as additional treatment options like UV blocking or scratch resistance coatings.
Another factor to consider is the Abbe value of lenses. This number indicates the quality and dispersing power of the material, while low Abbe values may cause chromatic aberration – a visible haze around the edge when light hits them.
If you need a lens material that’s both strong and durable, polycarbonate or Trivex plastic lenses are your best bet. These lenses have less shattering potential than glass and can withstand extensive use and abuse. Furthermore, these lenses are very lightweight and comfortable – perfect for people who play sports or spend time outdoors.
Glasses are more than just a fashion statement – they’re an integral part of your lifestyle. To look your best and stay contented, it’s essential that you find the perfect pair that meets all of your requirements.
For instance, you may require a pair of sunglasses that block harmful UV rays. In such cases, ensure the material meets ANSI guidelines for UV protection.
Additionally, ensure the lenses are designed in such a way that they evenly disperse different wavelengths of light. This property, known as Abbe value, plays an essential role in maintaining the optical integrity of a lens.
If you’re searching for a cheaper alternative to glass lenses, there are several plastic options. Polycarbonate is one popular option due to its high Abbe value and lightweight nature.
