JP2017003714A - Exhalation clouding prevention sheet for spectacle - Google Patents

Abstract

PROBLEM TO BE SOLVED: To prevent clouding of spectacles by changing flow of exhalation even when wearing a mask, by solving the problem that, when wearing a mask owing to pollinosis, and putting on spectacles, the spectacles are heavily clouded, and securement of a visual field becomes difficult.SOLUTION: A sheet (1) is connected to each frame of spectacles (2) or to a lower part of each lens, and a mask is worn from over the sheet (1). Hereby, moist exhalation leaking out from a mask upper part is prevented from entering a space between the lenses and eyeballs, to thereby prevent clouding of the spectacles.SELECTED DRAWING: Figure 1

Description

    The present invention prevents the glasses from becoming cloudy due to the exhalation of the person when wearing the mask.

    Conventionally, to prevent fogging of glasses when wearing a mask, the shape of the mask has been changed in various ways to make it difficult for exhalation to leak from the top of the mask, or an anti-fogging agent is attached to the spectacle lens. It is low.

JP2008-148984

Conventional anti-fogging methods are less effective and it is difficult to ensure visibility. In particular, with glasses that easily retain air in the space between the lens and the eyeball, such as pollen countermeasure glasses, the cloudiness is severe and dangerous.

  A flexible sheet (1) like a cloth is connected to the frame of the glasses (2) or the lower part of the lens, and a mask is mounted on the sheet. As a result, the flow of exhaled moisture leaking from the upper part of the mask is changed to prevent exhalation from entering the space between the lens and the eyeball, thereby preventing fogging.

  Even when wearing a mask, the inner lens of the glasses does not fog up, so a sufficient field of view can be secured and it is safe.

It is a spectacles attachment perspective view of the sheet | seat of this invention. It is a spectacles bottom view and a detachable seat figure. Example 1 It is a bottom view of glasses and a fixed seat diagram. (Example 2)

  A portion connectable to the lower part of the glasses is provided at the upper end of the sheet (1) having flexibility such as cloth, and the sheet (1) is attached to the glasses (2). The sheet (1) is connected so as not to be detached from the glasses (2) when the head is shaken.

  The sheet (1) is about the bulge (nose wing) on both sides of the nose and has a shape that avoids the nose wing and the bulge of the nose (back of the nose).

  This invention is a sheet | seat which changes the flow of an expiration | expired_time when a mask is mounted | worn with the above structure, and prevents fogging of glasses (2).

  The detachable sheet, which is one of the connection methods shown in FIG. 2, has a magnet (11) fixed to the upper end of the sheet, a metal piece (3) is fixedly attached to the lower side of the glasses, and the glasses (2) are attached by magnetic force. Connect the sheet (1). When not in use, remove the seat and take off easily. A magnet may be attached to the glasses side, and a metal piece may be attached to the sheet.

Moreover, it is also possible to take the form which can be attached or detached with a hook-and-loop fastener or a hook.

  A fixed sheet, which is one of the connection methods shown in FIG. 3, connects the glasses and the sheet with an adhesive (12) such as an adhesive or a double-sided tape. When not in use, peel off the sheet and take a disposable form.

Since the sheet comes into contact with the skin, the sheet can be used more comfortably by opening the hole (13) to the extent that the anti-fogging function is not lowered in order to reduce the contact area.
