The width of your glasses is important.
The width of your glasses is not just to make you look more attractive. It's related to the position of your pupils in each lens, which is inextricably linked to the quality of your vision. The frame could be slightly wider than the zygomatic bones. It should be wide enough not to touch the temple. It should be close to holding a finger. This is especially important for people who wear bifocals or progressive glasses, so you can see through the right part of the lens.
What Strength Reading Glasses Do I Need?
What strength reading glasses do I need? You can choose the reading glasses strengths by age or you can also perform a reading glasses test. If you are aging from 40 to 44, the +0.75 to +1.00 dioptre power is recommended. If you are aging from 45 to 49, the +1.00 to +1.50 dioptre is recommended. Age from 50-54, recommended power is +1.5 to +2.00 dioptre. Age from 55-59, recommended power is from +1.50 to +2.25 dioptre. Age from 61-65, recommended power is from +2.25 to +2.50 dioptre.
If you find two different strengths of reading glasses are available, choose the lower power because too strong strength can cause discomfort compared to weaker powered glasses and can even lead to nausea and dizziness.

Tungsten Carbon Steel Spectacle Frame
Tungsten-carbon steel is an upgraded version of TR90. Its characteristics are basically lighter, softer, and higher in hardness than the original TR90. It is said to be the material softer than water, lighter than paper, and harder than steel. Tungsten-carbon materials are also called yellow materials in the glasses industry, and the terms of tungsten-carbon plastic are only for consumers because consumers do not know what they mean.
In terms of raw materials, titanium is the most expensive material, and the value of raw materials determines the final retail price of the glasses. The cost of tungsten carbon is slightly higher than the price of TR90 by about 20%, which is about the same as the value of low-end alloy glasses. The cost and value of pure titanium are 3 to 4 times that of TR90 and low-end alloy glasses, so the basic price difference between a pair of brand new pure titanium glasses and TR90 glasses is very large.

Benefits and disadvantages of rimless glasses
Rimless glasses are more stylish colorful, and comfortable to wear, greatly easing the pressure on the bridge of the nose and eyes, and because there is no frame limitation, the wearer's field of vision is wider. They are loved by young people. After a period of time, the screws at the hole are easy to loosen. The wearer should often tighten the screws.(https://www.koalaeye.com/collections/rimless-glasses)
The quality and reputation of the store owner are affected. And because there is no support bracket, when the glasses are placed on a hard object, they will directly contact the lens, which is easy to cause lens wear. In addition, when the rotation or torque force is encountered, the force will directly act on the lens, so when the force is too large, it is easy to cause damage to the lens.
Who need progressive lenses?
There is no limit to the degree of progressive multifocal lenses. Whether it is nearsightedness, presbyopia or moderate astigmatism, it can be worn, but not everyone can wear it. There are two types of progressive multifocal lenses on the market, one is hard and the other is soft. The main difference between the two designs is the length of the progressive channel. The rigidly designed progressive film has a short progressive path and relatively less peripheral aberrations. In order to ensure vision at various distances, fewer vertical dimensions are required. For example, a teenage progressive film belongs to this design, but because of its short gradual path, the gradation process is too short. Fast. Compared with the elderly, this design is more difficult to adapt; the soft design of the progressive film has a relatively long gradation channel and relatively large peripheral aberrations, but due to its long gradation channel, the gradation process is relatively smooth, which makes it easy to wear glasses It is suitable for people with poor adaptability.
If you are a person who is able and willing to accept new things, understand and adapt to the temporary discomfort caused by progressive addition lenses, we suggest that he can wear a pair, if he has severe hypertension, dizziness and other symptoms, or People who have misunderstandings about progressive lenses and are unwilling to adapt should not try them. Because you first wear progressive multifocal glasses, you may experience: slight dizziness, shaking when walking, and being careful when moving up the stairs.
The perception of space has changed, the perception of the distance of the object, and the perception of depth have changed. New wearers should not drive immediately and do strenuous exercise. When you look close, you need to turn your eyes down, and your eyes are mildly uncomfortable. Seeing an object through the blurred vision area around the lens makes the object blurred. Therefore, when new wearers look at things, turn their heads more, turn their eyes less, try to use the far-use zone, the near-use zone, and the middle-distance zone to see objects.
Plate Frame
Glasses processed with acetate sheets become sheet frames. The plate frame is not easy to burn, the specific gravity is small, and the base arc is not irradiated by ultraviolet rays to change color. In addition, it has high hardness, good gloss, and durability, but it is not easy to bake and the temperature is 115-130 degrees. The style is more beautiful, and it is not easy to deform after wearing. The current market is that the plate frame combines the thickness of the plate and the metal texture, and combines different types of lenses to create fashion and personality. There are not only retro-style frames, but also popular frames, combining a variety of elements to create classic glasses frames. Its workmanship has undergone complex processes such as turning, grinding, and polishing, so it is relatively high-end.
