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.
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.

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.
Difference between green film and blue film
In addition to the usual hardening, anti-fouling, anti-reflection, anti-radiation, and other functions, the green film has remarkable anti-ultraviolet performance, suitable for people who work outdoors for a long time to use. In addition to the general hardening, anti-fouling, anti-reflection, and anti-ultraviolet functions, blue film’s anti-radiation ability is very good, and it is suitable for computer workers and other people affected by radiation greater.
The coated lenses were originally produced in green, mainly to distinguish them from the uncoated lenses. At 515 nm, the reflection increases the reflectivity by about 2%, so there is a contrast, and the green film is seen in the reflection. This film is the most standard anti-reflective film, and it is the best and oldest one available.
What color lenses are good for driving?
The optometrist reminded us that it is not advisable to choose pink, purple, light blue, and other colors with obvious decoration effects for driving sunglasses. These colored glasses basically cannot protect the eyes. In addition, they may change the color and cause chromatic aberration. Generally speaking, you should wear brown and gray glasses when driving. The brown lens can filter out a lot of blue light, which can effectively improve visual contrast and clarity. The gray lens can absorb any color spectrum in a balanced manner and will not produce obvious chromatic aberration after wearing.
Nowadays, the colors of lenses for sunglasses on the market are dazzling. Many people only consider whether they look good when choosing colors, and do not pay attention to the impact of lens colors on vision. When choosing sunglasses, we should not only pay attention to their decoration but also pay attention to their protective function for the eyes. We should avoid using blue lenses when driving because it will make us unable to distinguish the color of the traffic signal lights.
