Many traditional optical stores are complaining about a drop in customer numbers. When we analyze it, we find that the decline in customer numbers is divided into two aspects. The first is the decrease in new customers, which is mainly because the Internet and eye hospitals are fighting for customers from optical stores. The other is the loss of old customers, which is entirely because the optical store did not do the best service, especially the after-sales service. Confirm the...

Confirm the optometric data

It is necessary to confirm the accuracy of optometric data. If you stay up late or look at the phone or computer for too long before the optometry, leading to visual fatigue, it will increase the degree. But if you can let your eyes have a good rest, and then take optometry, the degree may be restored to the original situation, so you need to know the state of optometry, to check if it really had increased in degrees. The main purpose of progressive lens is to use it for people who have bleached eyes and often take off the lens.



Disadvantages of Progressive Lens

There are deformation areas under the left and right sides of the lens, which make the image blurry and irregular. It takes 1-3 weeks to get used to it. In addition, it has a narrower field of view in the near and middle distances, and long-term concentration on the narrow focal point can easily make the eyes tired. Suitable for people who need to alternate between distant, medium, and near vision.

However, with the development of science and technology, more and more progressive multifocal glasses have emerged that have a wider field of view, more comfortable wearing, and better meet the needs of eyes. Nowadays, the use rate of progressive lenses among middle-aged and elderly people abroad is quite high. Single-lens and double-lens reading glasses are gradually being replaced by progressive multifocal glasses.


Use them in exchange for a new pair.

A trade-in would be an excellent option. The old eyeglasses can be recycled by taking them to the optical shop, which is a low carbon and environmentally friendly.



How to Choose Reading Glasses?

Choose big frames the first time. When choosing reading glasses, you can choose the big frames for the first time. You may need larger glasses frames or lenses to really get the sweet spot of where the prescription is.

And if you have never worn glasses for eye conditions such as nearsightedness, farsightedness or astigmatism, it is likely you will be able to see well with non-prescription reading glasses. So, you can buy these non-prescription reading glasses.


The effects of night blindness on driving

As we age, our pupils will be narrow little by little, so they can't dilate as quickly. The smaller the pupil, the less light reaches the retina, making it harder and harder for the retina to see at night. This is called night blindness, and it's a condition that makes it difficult for your eyes to adjust from bright light to dim light. This makes driving at night especially stressful in your 50s, 60s, and beyond.



What Is Progressive Lens?

Progressive lenses, also called multifocal lenses, have three prescriptions in one pair of glasses. So, it allows you to see near, middle distance, and far objects without changing your glasses. The progressive lenses are designed for people who are over 40 years old who are both nearsighted and farsighted. The progressive lenses come with the following features:

  • There is no distinct line between all visions(near, intermediate, and far).
  • Most popular lens for anyone with presbyopia who wears
  • Expanded intermediate zone for better computer vision.

From the above information, you may have known the differences between bifocal lenses and progressive lenses. As for progressive vs bifocal lenses, which one is better? It is difficult to judge because each of them has unique features. So, if you do not know choose which, you can listen to the eye doctor.
