The weight difference between pure titanium frames and titanium frames
Titanium frames are slightly heavier than pure titanium frames, but they are both high-quality materials, so they are more comfortable on the outside. The specific gravity of pure titanium is generally 4.5, while titanium alloy is 8.9, which means the material is equivalent to half of the titanium alloy. So the frames are lighter in your hand.
Glasses are frequently replaced.
In the United States today, there are more glasses than people. Counting prescription glasses, sunglasses, and over-the-counter readers, there are now more than 400 million pairs on the market. According to the Vision Council, an industry group, they swap out a brand new pair of glasses every two years on average.
Recommended Glasses for Heart Shaped Face
Wayfarers frames: to balance out a wider forehead is by finding frames that have wide, prominent endpoints that extend out past your temples. This can draw the gaze up and away from your cheekbones, making your eyes the focal point. So, the wayfarers frames are recommended.
Cat-eye frames: if you do not know how to choose the best glasses for heart shaped faces, you can try the cat-eye frames glasses. They can be quite versatile and help contour your face, either balancing or highlighting prominent features.
Aviator frames: the last glasses for heart shaped face we want to recommend is the aviator glasses. They can work to draw the eye downwards and flatten the bottom part of your face. The aviator frame glasses can also add a balanced look and soften prominent angular features.
Characteristics of titanium frames
Titanium is widely used in the eyewear industry because it is not easy to deform, fade and has strong stability. The glasses frame made of titanium can highlight the noble taste and elegant temperament. The glasses frame made of titanium can be divided into pure titanium, titanium alloy, and beta-titanium frame three kinds. To learn about titanium frames, how to identify pure titanium frames?
Titanium frame has the benefits of low density, high strength, good mechanical properties, and strong corrosion resistance. The frame is very light and not easily corroded by moisture. However, due to the poor process performance of titanium alloy, machining is very difficult, the glasses frame made of hydrogen, oxygen, nitrogen, carbon, and other chemical impurities are more absorbed. The wear resistance of titanium alloy is relatively poor, and the production process is relatively complex, so the cost is relatively high and the workmanship is relatively complicated when using this material to make the spectacle frame. The price is much more expensive than the common spectacle frame.
Transition Lenses Problems
Here, we will show you some common transition lenses problems.
Transition lenses are typically embedded with photo-sensitive chemicals or coated with similar films that produce the shading effect when exposed to light. This process makes the lens more expensive to manufacture and focuses on prescription glasses, thus raising the transition glasses cost. The transition lenses cost may be twice of the regular glasses lenses.
When you are driving with the transition glasses, they will fail to work. Car windshields typically come standard with anti-glare effects or films and laminates that break up some of the direct sunlight that enters the vehicle. This will reduce the transition lens effects, causing them to register a non-lit condition when the direct sunlight can actually be very bright.
An unlimited discount is not reasonable.
5 discount, 3 discount, 1.5 discount, we can see that glasses category discount is lower and lower. But glasses are not consumable, like cell phones, appliances, or even less frequently than they are. Because, unlike consumables, it has an incompressible cost structure. Behind such discounts, there is sometimes the marketing strategy of raising the price of glasses first and then lowering the price.
