Driver's protective glasses
The principle of the driver's protective glasses is to use the special film on the glasses to reflect the strong light hitting the glasses back to protect the eyes. It can protect against ultraviolet, infrared and blue light on foggy and rainy days. In snowy weather and at night, the wearer can see the scenery more clearly, and it can also increase the vividness of red, yellow, green, white, and other colors, and eliminate the glare and reflected light of the oncoming cars when meeting cars at night.
Why do people like wearing rimless glasses?
Rimless glasses are not heavy in weight, so they are suitable for all skin types. Even if you have oily skin, because the glasses themselves are not heavy in weight, they are not easy to slip off. Since rimless glasses have no frames and are made of memory titanium alloy, they are not heavy, which greatly alleviates the pressure on the bridge of the nose and eyes and makes them more comfortable to wear. And because there are no frames, the wearer has a wider field of view.
What is vision insurance?
The term vision insurance is commonly used to describe health and wellness plans designed to reduce the cost of regular preventive eye care (eye exams) and prescription glasses (glasses and contact lenses). Some vision plans provide discounts on elective vision correction precesses, like LASIK and PRK. But unlike large health insurance plans, most vision plans are discount or health benefit plans that provide specific benefits and discounts on annual premiums. They can be used to cover most of the cost of eyewear, or they can be used to make high-end eyewear products and improvements, like progressive lenses, anti-reflective coatings, and photochromic lenses, which are much cheaper. Vision insurance plans usually operate differently than other health insurance plans or large medical insurance plans.
Single Vision vs Progressive: What Are Their Differences
With single vision lenses, you can also just use the center of the lenses to avoid prismatic effects if your prescriptions are very unequal for both eyes.
As for progressive vs single vision, they also have differences in frame selection. You will stick to frames when choosing progressive lenses that will provide you with a minimum height of 14mm from the point you are looking through the lenses into the distance to the point you are looking down while you read.
Besides the above differences, they are also some other differences between single vision glasses and progressive lenses. You can choose either one based on your needs. To choose glasses, Koalaeye glasses are recommended. They come in stylish and at a cheap price.
