Reading glasses are a necessity for those who are having difficulty seeing at hand.

However, reading glasses can be obtained at a 100-yen store, or at our store, they cost several tens of thousands of yen.

The price difference between a pair of reading glasses costing 100 yen and those costing tens of thousands of yen is roughly 100 times or more! What is the difference?

I would like to explain.

1 The left and right seldom have the same degree.

The basic premise is that there are seldom people whose left and right eyes have the same power (not vision).

It is only natural that the right eye and the left eye should be given different degrees of power for each eye.

What would happen if reading glasses with the same power on the left and right sides were put on a person with different power on the left and right sides?

The focal distance seen by the right eye and the focal distance seen by the left eye will be shifted, resulting in reading glasses that are very tiring.

2 Align the center of the lens with the center of the black eye

The size of the face and the distance of the eyes from the nose are different for everyone.

If the lens is not aligned with the center of the black eye, the force of the lens power will force the eye muscles to pull and turn the eye outward or inward. This is very stressful to the brain, which controls the eye muscles. This is called the "prism effect.

Just remember that if the center of the lens is not aligned with the center of the black eye, you will get tired.

3 Focal distance can be set to the distance you want

Those who sew, those who look at the computer all the time, those who like to read, in fact, often have different distances they want when it comes to looking at their hands.

For some people, 25 cm is best, while for others 40 cm is best.

If your reading glasses focus on 25 cm, they will be a little blurry when you look at 40 cm. The reverse is also true.

Professional reading glasses can be made for you if you ask us to make them so that they focus well at this distance.

If you have read this far, you have understood.

Reading glasses from a 100-yen store cannot fulfill even one of the above three requirements for most people.
(Or maybe you're one of those rare people who just happened to be there.)

We do not deny that it is a very tiring tool for long hours of concentrated work, although we do not deny that it can be used for emergencies, such as forgetting your glasses on the way out the door.

Professional reading glasses are personalized reading glasses that are made to minimize the stress of the user after careful consideration of the above three factors. We hope you can understand the difference.

Although we have focused on reading glasses in this article, there are various lenses that can solve inconveniences other than just reading glasses, so if you are interested, please let our staff know about your vision problems.
