With the spread of personal computers, word processors, etc., there are more and more opportunities to use VDT, which is a contact point between computers and humans. The CRT is most commonly used as the VDT. However, it is known that this cathode ray tube radiates a lot of electromagnetic waves during operation, which adversely affects the human body. In particular, the work of visually observing the cathode ray tube at a close distance for a long time has a great influence on the optic nerve, and causes eye fatigue, visual acuity loss, cataract, visual acuity disorder, headache and the like.

In order to satisfy both properties, there are severe restrictions on the gap between threads. In addition, there is a problem of peeling of plating and rust, and in order to prevent peeling and rust, the shield material must be incorporated inside the lens. Therefore,
It is troublesome to manufacture the target spectacles.
