The spirit behind celluloid glasses
Because celluloid material is flammable, it cannot be mechanized and basically needs to be created by hand, which forms a unique set of handcraft modes of Japanese crafters. Today, there are only a few celluloid factories in Japan, and the unique manual process and production are relatively small. This makes celluloid handmade glasses even rarer and more valuable. Celluloid was originally a very common and cheap material, even with a certain degree of danger, but because of the unique craftsmanship of skilled craftsmen, its performance was brought to the extreme, so that celluloid glasses became unique and sought after by some people. The material of the frame is an important factor that determines the comfort of the glasses. While ensuring comfort, people hope that the glasses can have a decorative effect and play a role in clothing matching in different scenes.

What factors make you receive glasses on the same day?
Are your lenses anti-glare or anti-scratch? This may extend the time it takes you to buy glasses. Is your prescription complicated? If so, it could mean your lenses take longer to make. Your favorite frames that you tried out at the store are just for display, so you have to order frames for your glasses. If that particular frame style is in small quantities at the factory, your delivery may be delayed. Some optometrist offices and eyewear retailers have in-house optics LABS. These LABS can make some eyeglass lenses in an hour or so. But the power and design of the other lenses needed to be manufactured by an external optics lab, which took more time.
Choose lenses with good optical clarity.
If you're wearing low-cost glasses, the quality of the polycarbonate lenses may not be as good as expected. If you wear a pair of safety glasses and the lenses look cloudy or have tiny distortions, it's a sign of poor optical quality. Lenses with excellent optical quality are free from aberrations and imperfections, and they allow to be seen using as close to natural vision as possible.
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.
How many degrees of myopia do I need to wear glasses?
Students are the most nearsighted because they need to read and study every day. Many people have myopia during their student days. During the physical examination, everyone will check their eyesight first. Generally speaking, if the visual acuity is lower than 0.6, it means that you may be near-sighted to 0 degrees. At this time, you need to go for optometry to see the specific vision situation and see if you need to wear glasses. If the visual acuity tested exceeds 200 degrees, you must wear glasses at this time. If you do not wear glasses, your vision will be greatly affected, and the degree of myopia will rise quickly. For this reason, you must wear glasses in time to correct your vision. If the degree of myopia does not exceed 0 degrees, this is pseudo-myopia and does not require glasses. However, you should always take care to protect your eyes, avoid staring at things at close range for a long time, and don't let your eyes get too tired, so your vision will slowly return to normal.
