Limitations of NXT lenses
NXT lenses made from Trivex can't be cut by means of traditional edge cutting ways, requiring certain edge grinders, which has caused some problems for retail stores. Therefore, now NXT lenses are more used in some glasses, like sunglasses, protective goggles, and so on.

Advantages of Progressive Lens
Continuous and clear vision throughout the entire process is the advantage of progressive lenses. Because the added value continuously increases gradually in the gradient zone, the wearer can obtain continuous clear vision from the far point to the near point through the gradient lens under the appropriate head position. In line with physiological optics, better adaptation. The appearance is better than that of double-lens and triple-lens. There is no dividing line of sub-sheets, and there is no ring-shaped blind zone and invisible sub-sheets.

Do night driving glasses work?
Yellow lenses reduce the amount of light entering the eyes, thereby reducing visibility. At night, this may be harmful, not beneficial.
Night driving glasses are available in a variety of yellow and amber colors. The darkest lens filters out the most glare, but also filters out the most light, making it difficult to see in dim or dark conditions.
Some night-driving glasses wearers report that they can see better when they wear them at night. However, visual tests have shown that night driving glasses do not improve night vision, nor can they help the driver see pedestrians faster than without them.
Should I wear driving glasses at night?
In fact, it is not safe to use any colored lenses while driving. You might consider how much color plays in your average driving experience. Red, yellow, green, orange traffic signs, and other vital signs are designed to remind you to pay attention to safety signals and directions while driving. However, if you see everything turn yellow, you may miss a sign and end up making the wrong decision at the traffic light, or worse, an accident.
Another disadvantage is that they do not have a prescription. If you are looking for a pair of standard night driving glasses on the market, you will find that most of them are standard over-the-counter glasses. To have night-driving glasses that can correct vision, you must customize them in an optical shop, and the price is much higher. Under the hype of the night vision feature, you can expect the cost of prescription night driving glasses to be too high.

What is the processing technology to make the lens thin?
For myopic lenses, the larger the diameter, the thicker the edge. Therefore, for customers with high myopia, we will recommend frames with smaller ring diameters, so that the edges of the processed lenses will be thinner. The edges of farsightedness lenses are already very thin (convex lenses are thick in the middle and thin on the sides), and the key determinant of lens thickness is the center thickness. In addition to the refractive index, which affects the thickness of the farsightedness lens, the influence of diameter is more important. Therefore, for patients with farsightedness, the most effective way to make lenses lighter and thinner is to choose a smaller frame and then customize a pair of lenses with the right diameter.
