Some combination racks are made of different discountglasses materials to create different parts, usually considering cost reduction or appearance requirements. If you're just a moat, go straight to the branded pure titanium.

If you can't afford pure titanium and have a particular preference for titanium and want to pursue cost-effectiveness, then choose titanium alloy. Its performance will not be inferior to titanium, and of course, some prices will not be cheaper than pure titanium.

Memory alloy is the most recommended frame in eyewear stores best place to buy eyeglasses because its characteristics are very obvious and can be easily demonstrated. There are many components of memory alloys, such as nickel-titanium alloy, gold cadmium alloy, and copper-zinc alloy, and the better quality is nickel-titanium alloy, which is also relatively expensive. The mirror legs of this memory alloy are usually made very thin like iron wire, so their weight is also relatively light.

An injection molded frame is a frame made of resin injection molding, which is cheaper than a sheet metal frame. The frame is softer and less elastic, and a line trace can be seen at the junction of the template. There is not a metal wire inside the mirror legs like a sheet metal frame. More commonly used on sunglass near me, optical glasses are generally not recommended.

PC frames have high strength, and hardness, and are not easily deformed. The obvious disadvantage is their low toughness, which makes it difficult to adapt to the head curve and is also prone to breakage. Generally, a metal wire is added to the lens legs of PC materials to increase toughness, which is not found in injection molded frames. PC frame has a variety of colors and can also be made semi-transparent, so it is often used for sunglasses or fashionable and decorative glasses.
