Need to re-adapt to new glasses
When the glasses were damaged, the glasses were not replaced in time. As a result, the nearsighted person wears old glasses and continues to look at things. The old glasses have 'remodeled' the eyes in the long-term process, and the eyes have adapted to the old glasses. Therefore, even if the power of the new glasses is the same as that of the old glasses, the new lenses will feel brighter. In this case, eyes produce uncomfortable symptoms. It is recommended to use the new glasses early the next morning. After a night's rest, the eyes will be easier to adapt to the new glasses. After a few days of continuous wearing, the dizziness symptoms will disappear.
Cellulose Acetate
Acetate is a kind of thermoplastic resin obtained by esterifying acetic acid to acetic anhydride under the action of a catalyst. Acetate is resistant to water, gasoline, mineral oil, and lipids, weak alkaline solutions, and acids, excellent weather resistance, not resistant to ethanol, strong acids, and strong alkaline solutions. During thermoforming, it is very necessary to dry the material before forming. Acetate was born in the early 20th century, and was successfully trial-produced and industrialized by the UK in the early 1920s. At present, it is the second-largest variety in cellulose fiber after viscose fiber. Acetate can be used to make textiles, cigarette filters, film bases, and plastic products.
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.
How Do Progressive Lenses Work?
How do progressive lenses work? You may have this problem. As is well known, when you are over 40, your vision begins to deteriorate and you may suffer the presbyopia condition. So, with the progressive lenses, you can see at all distances with one pair of glasses. They start with your distance prescription at the top of the lens and increase as you move toward the bottom of the lens.
Then you move your head position to allow you to focus through different areas of the lens. Move your head upwards to see something in the distance, hold it straight for intermediate or arm’s length vision and down for near vision for objects that are close up.
In addition, progressive lenses avoid the visual discontinuity or image-jump when your eyes shift from one zone to the other in non-progressive multifocals since there are no distinct lines in progressive lenses.
Brick-and-mortar stores have fewer customers.
Brick-and-mortar stores are known to have a significantly smaller customer base, targeting a particular county or even a particular region and population. Mainly aimed at young students.For physical stores, their income range is relatively narrow. Therefore, in order to make more money, every physical store can only make a profit by raising the single sale price. Online stores attract consumer demand from all over the country and the world through the Internet.
The role of blue light blocking glasses
Blue light blocking glasses can effectively isolate ultraviolet rays and radiation, as well as filter blue light. They are generally used when watching computers, TVs and mobile phones. In daily life, especially office workers, they often feel eye fatigue, dry and sore eyes, which are all caused by staring at the electronic screen for a long time.
Blue light blocking glasses can effectively reduce the damage of blue light to the eyes. The blue light blocking lenses can effectively block harmful blue light within a certain distance, resist the damage of lens diseases to the eyes, and reduce the visual fatigue caused by blue light. Outdoors can also reduce the discomfort caused by strong ultraviolet rays to the eyes, and avoid the damage caused by ultraviolet rays to the eyes.
Our eye protection should be always all-time, and we can’t rely on blue light blocking glasses. It can only block some of the blue light’s damage to the eyes. Whether studying or working, you must pay attention to the rest of the eyes and try to reduce the brightness of the electronic screen. More importantly, developing good eye habits is better than anything else.
