What are night driving glasses?
Night driving glasses are usually non-prescription glasses with yellow lenses and can be bought in many optical stores or online. Lenses range in color from light yellow to amber, and some night driving glasses have an anti-reflective coating. The yellow night driving glasses have been manufactured and sold for decades. They were originally sold to hunters as shooting glasses because they gave birds a sharper contrast to the sky on overcast or overcast days.
What is blue light?
Our daily lives are inseparable from mobile phones, computers, tablet computers, and other electronic products. Many people's eyesight is also going downhill due to long-term exposure to strong light electronic screens, and their eyes are more or less potentially adversely affected. It is found that many optical stores sell blue light filter glasses, which have the function of blocking 99.9% UV and scattered blue light, alleviating visual fatigue. They claim that these glasses can block short-wave blue light emitted by electronic products such as mobile phones and computers, and even prevent age-related macular degeneration so they are much sought after by consumers. The price of these so-called anti-blue-light glasses varies greatly, ranging from dozens of dollars to several thousand dollars. Do these blue light blocking glasses really have so many magical functions?
The natural light seen by the human eye is composed of a spectrum of different colors, including red light, orange light, yellow light, green light, blue light, indigo light, purple light, which gives people a visual feeling of white. Different wavelengths present different colors visually, and the shorter the wavelength, the higher the energy. At present, products with electronic screens such as computers and mobile phones use LEDs and other materials to emit light mainly in three colors of red, green, and blue, and blue light accounts for the main part. Blue light belongs to the range of visible light, belongs to short waves. And the wavelength is between 400 nanometers and 500 nanometers, which is close to ultraviolet and carries a large amount of energy. And this part from 400 nanometers to 450 nanometers is called high-energy short-wave blue light.

The lens material
Lens material affects the effect of protecting our eyes, so we should choose the kind of driving glasses made of polarized lens, which can effectively reduce the dazzling lights, and can filter out the redundant lights. When used at night, the powerful light is softened and the vision is clearer, thus ensuring the safety of drivers and relieving eye fatigue. If you can, let the seller dim the light when you buy, feel the softness and clarity of the light after wearing the product.
Different Types of Progressive Lenses
The ground-view progressive lenses are designed for people who enjoy the outdoors. These lenses are supposed to provide a natural feel to your vision and reduce lens distortion. Ground-view progressive lenses allow better vision through the sides and bottom of the lens, so they give you improved vision when driving, using computers and looking downwards.
The standard progressive lenses are exactly what they sound like. They offer a wide reading area and have a longer drop between prescriptions and require a larger frame. However, they are less specialized than other lenses.
OMBRE & TWO-TONED GLASSES
Gradient glasses and double-color glasses are popular for their visual appeal and ability to match almost anything in your wardrobe. Typically, these frames start darker at the top and then transit gently or abruptly to lighter shadows. Professional and fun all in one frame style.
How to buy glasses that have quality assurance online?
First of all, you need to find a good eyewear online store and determine if there is any discount information. Big glasses usually have preferential information, and there are certain preferential activities. Lenses are very important to us, so the best quality is good.

Choose a pair of good-quality glasses for this combination. Optometry is closely related to the quality of the glasses. If it's not accurate, your glasses must be substandard. If your optometry data is good, you will get a real pair of glasses. You need to make sure your optometric data is accurate, which is a process you must go through when wearing glasses online.
