The first number often refers to the lens width. Lens width is the horizontal diameter of the lens at its widest point. In optometry, another term is eye size.
The second number often means the bridge width. Bridge width is the part that joins the two lenses and sits over the nose. Some refer to this as the gap. The bridge width varies between 14 and 24 millimeters.
The third number often means the temple length. The temple is the arm that keeps the sunglasses on your face. That arm extends to the part that hangs on the ears. The length is usually 135, 140, or 145 millimeters.

Try not to choose the product with spray paint on the surface, because durable time is shorter.
You should pay special attention to that TR, plastic steel, stainless steel, wood, β titanium glasses temple may not be adjusted. When trying on, it should be noted that the weight of the lens has not been added to the trying frame, to avoid the problem of discomfort (such as an easy slip of the frame) found after the preparation.
What Is Photophobia?
There are a lot of reasons causing our eyes discomforts, such as moving between indoors and outdoors on bright sunny days, staring at computer screens all day, driving at night, or watching TV. If the discomfort worsens over time with accompanying symptoms such as intense pain, excessive squinting, excessive tearing or burning sensations, it may become an eye condition called photophobia or light sensitivity.
One of the symptoms of photophobia is intolerance of light. To some degree, most of us are sensitive to bright or fluorescent lights, but those suffering from photophobia may experience a range of symptoms - from minor or mild irritation to serious debilitating reactions. The symptoms can include dizziness, headaches, migraines, server eye pain, excessive blinking, blurriness, and eye inflammation.
So, they are a few ways to combat photophobia.
Should I wear glasses all the time for myopia?
Wearing glasses is more to correct your vision and protect your eyes, so as not to worsen myopia. If you are nearsighted but don't wear glasses, it will have a lot of impact on your eyes. First of all, after a person is nearsighted, seeing distant things requires a lot of adjustments to the eyeballs, which will make your eyes tired easily. Over time, your myopia will increase quickly. When we are nearsighted, sometimes the myopia of the two eyes is not the same. If we do not wear glasses and correct vision, this will affect the normal development of vision. The difference between the powers of the two eyes may become larger and larger, which is easy to cause a squint. After myopia, if you want to see far away things clearly, you need to squint your eyes harder to see clearly. Therefore, some nearsighted eyes often squint when they are not wearing glasses. However, the action of squinting will cause the upper eyelid to form a pressure on the eyeball, and squinting for a long time can easily cause amblyopia. Squinting your eyes for a long time will also make your eyes smaller and affect your appearance. Therefore, once your myopia exceeds 200 degrees, you must wear glasses in time.
Heart-shaped face with angular glasses
The heart-shaped face is also a common face shape in daily life. This face shape is somewhat similar to the inverted triangle face shape. Generally, the chin is a relatively sharp face shape. For this type of face, the most important thing is to modify the cheekbones above the nose to highlight the slenderness of the chin. Therefore, it is better to wear a pair of angular glasses, which can effectively modify the facial lines and look more perfect.
Features of pure titanium glasses frame
Due to the lightweight (ordinary nickel-based alloy frame weight 48%-60%), high strength, corrosion resistance, surface easy coloring, beautiful and durable features of spectacle frame made of pure titanium, they have been loved by most consumers. But the elastic modulus of pure titanium is higher (about 120GPa). The temples of the frames made from them are not elastic enough. After wearing the glasses for a period of time, the temples of the glasses need to be adjusted due to the relaxation of the stress. The processing plasticity of titanium metal is worse than that of other metal materials, so the processing technology of its wire is difficult. The surface quality is difficult to control, and the technical content is high. The surface quality of pure titanium wire produced by a few domestic manufacturers is poor.
