Take Frame material selection seriously.
When choosing a frame, try to choose a light frame. At present, the glass frame material is relatively light titanium, tungsten carbon, TR90, and so on. Now based on the plate spectacle frame, the new plate spectacle frame implements thin processing, so the whole spectacle frame has become light up. You can use rimless light glasses. Usually, the nose pad will leave an indentation, possibly because the glasses are too heavy. Changing some light glasses can improve the problem of indentation of the nose pads.
Bifocal Lens
Bifocal lenses have two observation areas separated by visible lines, a larger observation distance area, and a smaller reading area. It may take some time for people who are wearing bifocal glasses for the first time to get used to the lenses. This is mainly due to learning how to move the eyes between the observation distance area and the reading area. Some people will also find that there will be an 'image jump' phenomenon at the visible line between the distance and the reading area, especially for those with limited mobility, who must look down when walking. The best way to get used to bifocals is to wear them as much as possible.
What symptoms does myopia have?
Myopia is a problem related to the eye's ability to focus on distant objects. The manifestation of myopia is that blurred vision at a long distance. But near-distance vision is good. Early myopia often has long-distance vision fluctuation and squinting when looking at distant objects. Because looking close need not or less use an adjustment, and set function is weakened correspondingly. Those with high myopic have poor far vision, often accompanied by poor night vision, floaters, and other symptoms. Changes in the fundus of the eye can occur to varying degrees. It can form irregular shape white atrophy spots and so on.
Blue light and anti-reflective lenses
They reduce the potential for cumulative damage to the eyes.Allowing the beneficial blue light through improves clarity, they reduce glare and reflection. They can improve your visuals and reduces eye strain and nighttime reflexes. They can reduce the symptoms of computer vision syndrome, including eye strain, eye strain, and headache.
Bertoni polarized glasses
Bertoni polarized night vision driving glasses are made of strong, flexible, durable, and ultralight polycarbonate. Yellow polarization increases contrast, improves visual acuity, and filters out blue light. They are great for drivers, cyclists, and winter sports enthusiasts. The driving glasses with polarized yellow lenses block glare from headlights, reduce night driving glare, improve night vision, and improve color clarity and visual clarity. They are ideal for driving in low-light conditions. Most sports sunglasses glasses frames and goggles are made of polycarbonate because of their strong, thermoplastic, lightweight, and impact resistance features.
How to choose progressive lenses
The progressive lens can effectively control the deepening of myopia, but there is no reliable empirical evidence. At present, the height of the lens frame is only about 30mm. The distance from the design of the transition interval is not enough, and the comfort of the eye is difficult to adjust the short distance. From the quality and technology, the foreign brand design process is stable and mature, but the price is too high, there are still a lot of people who are not easy to adapt. The parameters of progressive lenses need to be determined by strict optometry.
