They are lightier and cheaper than regular sunglasses because they are made from polycarbonates.
This classification includes establishments primarily engaged in manufacturing ophthalmic frames, lenses, contact lenses, and sunglass lenses.
Use toothpaste.... takes the scratches of and makes them look brand new! (:
I have used Pledge before and it usually works great on scratches.
Unfortunately, if you scratch your sunglass lenses - you will need to replace the lenses completely as the scratches cannot be polished out. If you purchase a pair of designer sunglasses from a reputable supplier, they can usually order replacement lenses for you.
It depends. Most large sunglass companies like RayBan install high-end sunglass lenses into their glasses and have been doing them for years.Do I think these lenses are better that the ones that are out now? No, but I think some eye protection is better than none.
Most sunglass frames can be fitted with prescription lenses. You probably need to visit an optometrist to get the right prescription lenses.
To tint sunglass lenses, you can use a lens tinting solution or film, which is often applied through a dyeing process. First, clean the lenses thoroughly, then immerse them in the dye solution for a specific duration, depending on the desired tint intensity. Alternatively, you can apply a pre-cut tinted film directly onto the lenses, ensuring there are no bubbles. After tinting, allow the lenses to dry completely before using them.
Blue sunglass lenses offer several benefits for eye protection and style. They can help reduce glare, improve contrast, and provide better color perception. Additionally, blue lenses can block harmful UV rays and blue light, which can help prevent eye strain and damage. In terms of style, blue lenses can add a trendy and fashionable touch to your look.
A polarized lens cuts more reflected glare but the actual protection of polarized lenses and G15 lenses are the same. Polarized sunglass lenses reduce glare reflected off roads, bodies of water, snow, and other horizontal surfaces where the G15 lenses do not.
the color of the lenses doesn't matter. It's the amount of protection on them. Often there is a sticker on the lens when you first buy the sunglasses that will tell you the amount of protection they offer. The higher percentage, the better!
Polarized sunglass lenses are typically made from materials like polycarbonate, glass, or CR-39 plastic. Polycarbonate is lightweight and impact-resistant, making it a popular choice for sports and outdoor activities. Glass lenses offer superior optical clarity and scratch resistance but are heavier. CR-39 is a lightweight plastic that provides good optical quality and is often used in prescription sunglasses.
To darken sunglasses lenses, you can use tinted sunglass lenses that are darker in color or have a higher level of UV protection. Another option is to use polarized lenses, which reduce glare and make the lenses appear darker. It's best to purchase sunglasses that already have the desired level of darkness rather than try to alter existing lenses.
