Transitions® Photochromic Lenses

When you step outside, it immediately begins to darken. The lenses help prevent harmful blue light from digital devices, screens, and sunlight to help reduce glare and prevent eye strain. They have the function of 100% UV blocking,anti-reflection treatment with blue light protection. They can constantly adapt to changing daylight conditions to reduce excess light and optimize color contrast and polarized light to prevent dazzle. They filter out excess light to provide maximum comfort. And provide high contrast and minimize glare. They provide increased color recognition and depth perception.



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. The price can be considered as the average level because low-level lenses are best not to prevent damage to our eyes. The frame is not that important, and it is only used to support the lens. 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.


How to buy contact lenses online?

Choose a standard retailer. Contact lenses belong to three types of medical device products, and the sale of contact lenses and their care solution belongs to medical behavior. No matter it is an optical shop or contact lens e-commerce website, it must have a Medical Device Trading Permit before it can be sold. The trend of buying contact lenses online is obvious, and there are a lot of websites of individuals and contact lenses that do not have business licenses. Therefore when the user buys a contact lens on the net, be sure to look for management qualification of Medical Device Trading Permit, guard against being cheated.



The design evolution of progressive lenses

Spherical and aspheric designs

The design of the front surface of the far-use area of the early progressive lens is similar to that of the ordinary spherical single vision lenses, so it is called a spherical progressive lens. Since 1974, the front surface of the far-use region of the lens is designed to be aspheric by designers, which not only reduces the peripheral aberration but makes the lens thinner, lighter, and less powerful.

Hard and soft design

For hard design, the channel is short, and the gradient is large. The near-use area position is high. The effective visual area of remote and near-use areas was larger. Peripheral astigmatism is relatively concentrated. Because surrounding astigmatism increases rapidly and the distribution is dense, the curve effect is more obvious. The gradient area is narrow. It is more difficult and takes longer for wearers to adapt.

Lenses with soft designs have slower gradients, longer gradients, and wider gradients. The angle of rotation of the eye from the far area to the near area is greater. It's easier to get used to. Compared with the hard design, the effective visual area of the far and near use areas is smaller, and the location of the near use area is lower.

Single, diverse, and individualized design

Initially, the progressive lenses used a single design, in which each basic curve was scaled equally and a luminosity combination was added within the range of its semi-finished lens blanks. The steepest base curve uses the same lens design as the flattest base curve. Lenses designers quickly realized that the overall performance of the lens could be improved by microcustomizing the lens design, leading to progressive lenses with multiple designs. This kind of design is called diverse design. By the mid-1990s, there was the emergence of individualized lens designs. In addition to using different gradients, these first individualized lens designs used steeper baseline curves with a slightly larger approach area to compensate for increased magnification and reduced field of view.

Symmetrical and asymmetric design

There is no difference between the left and right eyes in the symmetrical design of progressive lenses. As the eyes turn inward when they see near objects, the gradual gradient area gradually tilts to the nasal side from top to bottom, so the left/right progressive lenses should be rotated clockwise/counterclockwise respectively during processing. An asymptotic lens with left and right eye divisions is called an asymmetric design. The gradient is gradually and moderately inclined to the nasal side from top to bottom. The refractive force, astigmatism, and vertical prism of the two sides of the left and right gradient of the asymmetric design lenses are basically similar. At the same time, considering the characteristics of eye movement parameters in binocular vision, the peripheral aberrations of the corresponding positions of the left and right lenses were appropriately balanced to improve the visual effect of the wearer.


In recent years, the glasses chain has developed fastly, especially in large and medium-sized cities. The professional glasses stores use their own technical force, progressive optometry equipment, and years of store reputation, which drives the whole industry to improve the quality of products. Nowadays, with the development and expansion of the eyewear industry, eyewear chain stores have become the main force of eyewear product sales in China and even the world. Moreover, tens of thousands of people are directly or indirectly engaged in the operation or management of eyewear chains or related to them. The eyewear industry provides us with a large market and benefits.
