What is a good progressive lens?

No matter how close the objects you see, the lenses are guaranteed to give you a clear view. Whether it's working with a computer, using a smartphone or tablet screen, or simply reading the newspaper, it's all about bringing a comfortable feeling for you. At the same time, the lenses have greater contrast and clarity. The lenses have been tested and approved by the wearer to ensure customer satisfaction, including quick and easy adaptation.


Advantages of progressive multifocal lenses

The progressive multi-focal lens has a number of different focal points from top to bottom. There's a smooth transition between seeing far and seeing close. There is no clear dividing line in the middle, like the myopia glasses, quite beautiful, and it is not dangerous. Because the added value is continuously and slowly increased in the gradient area, the wearer can get a continuous clear vision from the far point to the near point through the progressive lenses with the appropriate head position. In line with physiological optics, They help a better adaptation. Since the lens degree changes little by little, there is no phenomenon like jumping. Because the degree of the lens is gradual, so the vision from far to near changes slowly increase, which will not produce the adjustment of the eye fluctuation. It is not easy to cause visual fatigue. Without a degree line, the appearance will be more beautiful. Clear vision can be obtained at all distances within the visual scope. A pair of glasses satisfies both close and middle distances.



The Advantages of Trifocal Lenses

The greatest advantage of trifocal lenses is that they have three prescriptions in one, which means that not only do you not have to buy three separate pairs of glasses, but you also won’t have to constantly change them as you go about your day.

Another advantage of trifocal lenses is that in some cases, they offer a broader viewing area for near and intermediate-distance applications like reading and using the computer.


What Are Transition Lenses?

Transition lenses, also called photochromic glasses are eyeglasses lenses that change their colors with light. The transition lenses darken in the sunlight and lighten in the softer light or the dark. These transition lenses provide the convenience of sunglasses without having to wear them over your prescription glasses and having to constantly switch between the two.

But there are some common transition lenses problems. So, we will list some of them. Are transition lenses worth it? After reading this post, you will find them.



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.


Recycling glasses is one of the projects.

Eyewear recycling is one of the Lions Club's most high-profile and well-known programs. Lions Club has been collecting eyeglasses for over 80 years and Vision Recycling has been the official program of Lions Clubs International since 1994. Refractive errors can be easily corrected by wearing glasses, but millions of people in developing countries still do not have this basic eye care. Lions' collection of glasses enabled many people in these countries to see clearly for the first time. Lions also collect used hearing AIDS!



How did the eyeglasses market develop?

With the discovery of clear glass paste in the 14th century, lenses became cheaper and easier to sell outside Venice. In the 15th century, the invention of the printing press made it easier to read, which greatly increased the demand for glasses. By the 16th century, frames were made of luxurious materials such as horn, leather, and whalebone. They used real turtle shells. The artificial plastic celluloid was later used to make frames that had never been seen before. In the 1950s, glasses became more popular than ever. Even today, glasses are considered one of the best fashion accessories. Different colors and styles of frames can be made according to the face shape. New technologies for lenses, contact lenses, and even frame materials continue to evolve year after year.
