METRONOME DESIGN INC.

This is OKD from METRONOME-Tokyo.

I've gotten used to living in a sleeping bag recently (although I still have a home to go back to).

That aside, the sun has been really strong recently.

It's been hot lately.

First attempt at sunglasses for the summer

Or perhaps many people will buy new ones.

So this time,

OKD, a staff member at a sunglasses store,

Basically, the thing to check is the size.

If I'm not making a huge mistake here,

It's fine for everyday use.
(*Only applies to non-prescription eyewear)

First of all, when it comes to choosing sunglasses,

At the very least, you should check the size.

Frame size notation

Take a look at this image.

You may often see notations such as 46□22-138,

At a glance, it's hard to tell which is which.

From left to right, these are the lens width, bridge width, and temple length.

In the diagram below, these are 1), 2) and 3).

In other words, the size notation is 46□22-138

When I saw them, I realized that the size of the sunglasses was

It is as follows:

Size (mm)

1: Lens width 46

2: Bridge width 22

3: Temple length 138

How can I make sure the size is right?

First, compare it with the total lens width + bridge width (in the example above, 46 + 22 = 68).

Is there any deviation in the width of the center of your eyes?

Let's check.

This is PD,

In Japanese, it is called interpupillary distance (Dokkokankyori).

This is called the distance between the centers of the left and right eyes.

In the case of non-prescription lenses, this must not be significantly misaligned.

There's no way you won't be able to use it.

Also, be sure to check the length of the temples (3) .

This is also an eyewear (decorative item)

If that's your primary use, it's fine as long as it's not too far off.

Of course, you can also consult with an eyeglass store about fitting.

That's fine.

If the frame is designed and sold for Japanese people,

The numbers around here don't match up significantly.

I don't think this happens very often.

However, foreign brands and

When it comes to products aimed at foreigners, the design itself is

Since it is intended for overseas markets, the width and temple length are

There may be cases where it doesn't fit .

Therefore, when purchasing a brand for overseas markets,

Pay close attention to the size label.

lastly,

Other options include lens color and blue light processing.

I think it's best to customize it to your liking.

The design also depends on the face,

Basically, I think it's fine to like what you like.

If you are still concerned, ask your optician to recommend a similar shape.

Trying on sunglasses,

You can also ask people around you for their opinion on whether it suits you.

Although the above is simple,

How to choose sunglasses for summer.

Well then.
