Dark-rimmed glasses with wider frames

When choosing dark frames for round faces, one should pay attention to the width of the frames. If dark frames give people a feeling of narrowing, then the frames will appear smaller. Small frames make your face look bigger and rounder, so choose frames that are wide. If you can't wear a wide frame because the lenses are too strong, skip black and opt for something lighter.



Titanium frame machining is complicated.

The elastic modulus of titanium alloy is small, which is easy to produce large deformation, springback, distortion, and vibration in cutting, resulting in poor geometric shape and accuracy of the workpiece. As the surface roughness increases, the tool wear increases. The thermal conductivity of titanium alloy is poor and its thermal conductivity is small, 1/6 of that of 45 steel, so the high heat generated in processing cannot be effectively diffused. It is even harder to use titanium to make glasses. The frames are very thin and a lot of fine work is demanded. It's definitely a challenge for titanium, which is pretty difficult to work with. In addition, titanium alloy frames involve titanium alloy welding technology, which is more difficult.


How do I choose the right glasses frames?

Choosing a frame is largely a matter of personal preference. However, in addition to the style, you need to check the comfort level to see if there are problems like ear clips, nose compression, skin irritation, and so on. Please note that if you are highly short-sighted, try full-frame glasses, because full-frame glasses can hold heavier lenses more reliably. Below are a few easy ways to determine which frames would best flatter your face and show off your style and personality.

Step 1: Identify your face shape. Identifying your face shape is a good place to start when it comes to learning how to select frames which will suit your face shape.

Step 2: Choose colors that complement your skin tone. If you have a cool-colored skin tone, opt for shades of black, gray, and blue. If your skin tone is warm, you would benefit from warm colors, such as tan, pink, and red. As always, when you learn how to select frames, it is easy to know which colors suit your skin.

Step 3: Consider your way of living. When considering how to select frames for your lifestyle, one of the most important things is to make sure the frames fit at the bridge of your nose. This will allow your glasses to stay put better. If you exercise often, comfortable, sturdy frames are a must. If you want to look the part at an important business meeting, you can choose stylish frames with a variety of angles. If you need sunglasses for the beach, go for soft, colorful frames that will complement your relaxed vibe.

Step 4: Flaunt your personality.Frames are the perfect way to show off who you are and your personality. In the process of learning how to select your frames, you cannot forget to choose those that show off your personal style. You can find the perfect shapes, colors, or patterns, but those qualities mean very little if you aren’t comfortable.

Can You Put New Lenses in Old Frames?

In this section, we will show you how to replace new lenses with old frames. In general, optical shops will replace the lenses for you if your frames are in good condition and the shapes of the lenses is not too complicated.

So, can you put new lenses in old frames? Of course, you can do that if your old frame is good and shape of lenses is not too complicated.

However, glasses lens replacement depends on the quality of your existing frames, their conditions, and your prescription specifics. Not every pair of sunglasses or glasses for that matter can be reglazed. Sometimes fresh frames are required to match your new lenses. By far the most common reason for this would be because the existing frame is becoming brittle or is otherwise at risk of breaking. There is no point putting beautiful new lenses into a frame that breaks either during fitting or soon after.

In addition, when considering glasses lens replacement, you need to consider the materials of frames. In general, plastic frames are more likely to become brittle with age than metal frames. Of course, there are some other factors to be considered.

To protect the lens.

Avoid getting chemicals on your glasses, and if you do, rinse with water immediately. If there is sweat and grease on the glasses, they should be washed to avoid corrosion. Do not use clothes or towels to wipe the lenses. Rubbing the lens with a rough cloth can cause scratches on the surface of the lens. So it is best to use special glasses cloth when you wipe the lenses, and when you wipe the glasses, you must hold the glasses on one side of the frame with your hand, and then gently wipe the glasses with the glasses cloth. Remember not to overexert, otherwise, it is easy to cause frame and lens damage.
