People often wear metal eyewear will find metal eyewear nose pads are easy to get dirty and difficult to clean up. Some metal eyewear causes wearer allergic reactions, dirty nose pads may be one of the reasons, following we will discuss how to clean metal eyewear nose pads?

There are 80% metal eyewear wearers ignored for cleaning nose pads, some wear a pair of metal eyewear for a year without nose pads cleaned. As time passes, nose pads have turn to yellow and dusty. This is not right, metal eyewear nose pads should always be cleaned and replaced on time. Generally, nose pads lifetime is about six months, and metal eyewear nose pads need to be replaced every six months.

Metal eyewear nose pads are generally made of transparent silicone material, or soft PVC plastic material. These materials are friendly fit on face without nose pads indentation.

Metal eyewear nose pads cleaning refer to the following method:
Metal eyewear nose pads are generally active leaves of nose pads, simple to replace.
You can use a small screwdriver to remove nose pads, disinfection, cleaning and then put on.
For yellowed nose pads, you need a pair of new nose pad to replacement at your local optometrist.

Metal eyewear is one of the popular eyewear materials, Metal eyewear with small and delicate features. However, if you don’t pay attention to buying a piece of right metal eyewear, it is possible to buy a piece of relative not sophisticated metal eyewear. Then let us take a look at how to buy an excellent and reliable quality of metal eyewear.

First of all, the part of metal eyewear should be noted is the welding/ solder point, welding/ solder area is small but reflect the level of craftmanship of metal eyewear. When observing welding/ solder point, to pay careful attention on welding cracks. If there are cracks, then the metal eyewear manufacturer cannot properly dispose of welding/ solder effects, the metal structures were damaged.

And it should be noted that if there are any pseudo soldering, non symmetry welding/ soldering and material fatigue issues. If have any of these issues, it had better do not buy it to avoid breaking when wearing in daily life.

As for a piece of right metal eyewear, it must be very strong and immaculate clean welding/ solder points. Most important is where welding point to point need wrapped via molds called “Die mold” to processing welding. Thus welding effect will reach to very precise position between welding point and point.

B15 is Brown sunlens, the G15 is a grey/green sunlens, and both two sunlenses light transmittance are 15%. B15 and G15 sunlens are just different on colors.

G15 sunlens is more classic, G15 suitable for indoor and outdoors, while B15 more suitable for very much strong sunny days.

So G15 and B15 is light reduction lens, which banned 85% light and reduce overall brightness.

Polarized is just another function lenses, it can eliminate light in one direction, Polarized eyewear set a angle to eliminate reflections caused by such as water, moisture or strong light shining pavement and sandy ground, snow reflected light tec., it more suitable for driving, fishing and outdoors activities.

As professional eyewear supplier, we can produce Polarized metal eyewear, handmade acetate eyewear in various lens colors.

Usually there is a plating/painting layer on the surface of metal eyewear, there are following simple aspects to judge the plating or painting quality of metal eyewear.

Appearance

Observing metal eyewear plating layer, no pitting and uneven place, if there are pits or uneven place, the quality of metal eyewear is relatively poor.

It also can try to get metal eyewear cross on white A4 paper, see if there are any fading.

Touching

Metal eyewear under the rub with fingers, or gently claw with nails, see if there are any fade or the fingers tinted with painting colors. The quality of metal eyewear better, the fade or tinted won’t occurred.

Previous article we briefly introduced how to identify painting or plating finish for metal eyewear.

As we understand generally plating finish metal eyewear more firm and compact than the painting finish metal eyewear. According the disadvantages, how to make painting metal eyewear more firm and compact?

Normally, before metal eyewear painting processing, it should be plated a layer of chrome finish first, it can make painting metal eyewear as firm and compact as plating finish metal eyewear.

Chrome finish divide into white chrome and black-chrome finish. Black or matt black metal eyewear used black chrome finish; other painting metal eyewear used white chrome finish. To take an example, White, Red, Blue, Green, Purple, Yellow etc…

Why chrome finish can make painting finish metal eyewear as firm and compact as plating finish metal eyewear?

This is because chrome finished metal eyewear surface can form a honeycomb-like structure, which greatly improved the adhesion of painting on metal eyewear. Below picture under microscope for reference.

As for a metal eyewear supplier, the disadvantage of Chrome finish metal eyewear is that it is high difficult to rework .

During the metal eyewear production, the last producing process is painting or plating finish.

Painting or Plating finish is to spray or plating a layer of protective material on the metal eyewear; it can make the metal eyewear more beautiful, shiny, and more anti-corrosion.

How to identify the metal eyewear is painting or plating finish?

Generally, metal eyewear plating only three types: gold, silver, and gun with various colors such as light, middle, and dark colors.

Except for gold, silver, and gun, all other metal eyewear colors are panting finish.
To take an example, Black, White, Red, Blue, Green, Purple, Yellow etc…
These metal eyewear colors are all painting finished.

Compared with painting metal eyewear, plating metal eyewear plating layer is more firm and compact.

Choosing the perfect metal eyewear is not easy; learn how to buy high quality metal eyewear is very necessary. Following points to help consumers understand more about high quality metal eyewear.

In the earlier days, pure titanium metal eyewear processing is major on pure titanium, but in order to greatly pursue metal eyewear strength, flexibility, and improving welding difficulty grade, other metal elements such as aluminum, vanadium, molybdenum are added in pure titanium metal eyewear.

As pure titanium metal eyewear processing techniques and workmanship are difficult, titanium metal eyewear is high valued-added and sells much expensive than normal metal eyewear and has becoming the fashion trends, pure titanium is one favorite eyewear material now widely used in optical frame and sunglasses model. Refers to pure titanium metal eyewear, it means titanium components reaches to 99% or more. It has some difficulties in machining processing, welding, electroplating and so on, so the pure titanium application is subject to certain restraint.

In order to identify pure titanium and titanium alloy metal eyewear, consumers can refer to the below two points.

Pure titanium metal eyewear was marked with the abbreviations or full name in the frame, usually on the temples or on demo lens. It marked “Ti” “Ti-P” or “ Pure Titannium” or “Titannium”.

Usually, titanium alloy metal eyewear was marked with abbreviations in the frame, on the temples or on demo lens. It marked β-Ti or β-Titanium.
