How to clean the lenses?
When wiping lenses (especially the rimless glasses of resin lens), you must use a special wipe lens or soft handkerchief or paper. When you wipe the lens, you can only wipe it in one direction, not in circles, and don't touch the lens with your fingers. When the lens is stained with dust and sand, it should be washed with water before wiping, otherwise, the lens is likely to be abraded, and the operation should be gentle. At ordinary times, when cleaning, do not exert too much force, pay attention to the grasp of strength. When wiping the lens, it is best to take the side frame with one hand, and the other hand takes the glasses cloth to wipe gently. In order to prevent the lens film layer falls off, do not use alkaline detergent to wipe the lens. Therefore, when bathing or playing at the seaside, glasses should be properly kept to avoid water vapor or seawater caused by corrosion of glasses.
Can clear lenses be polarized?
At present, there are no clear polarized lenses. A polarized lens is a thin film vertically arranged with silicon crystal coating placed inside the lens, just like a shutter, which covers the parallel light and only allows the vertical light to pass through. In this way, the glare from all directions can be eliminated, so it is clear and comfortable to wear. Transparent polyamide, the material of nylon lens, is a new variety of polyamide. The material of the nylon lens is mainly transparent polyamide. Due to the effect of the light filter, only light from a specific direction is allowed to pass through the lens, which filters the dazzling light from the sun on the water, land, or snow very well. It can not only make the landscape soft, clear, and natural but protect the eyes to a certain extent.
The Price of Progressive Lens
On both sides of the lens of the progressive lens, some places are deformed, which makes the image blurred. In addition, it has a narrow field of view in the near and middle distances. The narrow focus point for a long time can easily make the eyes tired. It is suitable for the alternate vision of far, middle, and near. Under normal circumstances, the price of the progressive lens is different from the purchase merchant, region, brand, and quality, but the price of the progressive lens on the official website is between 30-85 US dollars. Of course, some products will be less than $30, or more than $85.
Dark-rimmed glasses with wider frames
When choosing dark frames for round faces, one should pay attention to the width of the frames. If dark frames give people a feeling of narrowing, then the frames will appear smaller. Small frames make your face look bigger and rounder, so choose frames that are wide. If you can't wear a wide frame because the lenses are too strong, skip black and opt for something lighter.
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.
