Fog-free swimming goggles

Abstract

A type of fog-free swimming goggles for sports, which prevents fogging when worn, allowing swimmers to clearly see all objects within their field of vision throughout the swimming process.

Description

[0001] A type of fog-free swimming goggles, specifically designed for use during swimming.

[0002] Wearing goggles to protect your eyes while swimming on ice is something every swimmer should do. However, the goggles currently in use fog up after only ten minutes, making it impossible for swimmers to see anything in front of them.

[0003] There are currently two methods to solve the above problem:

[0004] The first method is for swimmers to repeatedly take off their swimming goggles, soak them in water to defog them, and then put them back on.

[0005] The second method is to spray a chemical anti-fog agent onto the lens of the swimming goggles, which can prevent fogging for several hours. However, the anti-fog agent can easily get onto the eyeballs and damage them. Except in competitions, swimmers generally do not use anti-fog agents.

[0006] The purpose of this invention is to provide a fog-free swimming goggle. This fog-free swimming goggle will not fog up when worn, allowing swimmers to clearly see everything within their field of vision while swimming.

[0007] This invention achieves its functional objective by leaving a space in front of the lenses of ordinary swimming goggles, and then adding another layer of lenses. This creates a sealed air gap between the two layers, which is filled with an inert gas to improve the heat insulation effect. This air gap utilizes the principle of hollow insulation to block the temperature difference between the outside environment and the face and eyes, thus preventing fogging.

[0008] The fog-free swimming goggles of this invention are simply ordinary swimming goggles with an added lens layer. However, the increased production cost and selling price are very low, yet they allow swimmers to see everything clearly. In particular, these fog-free swimming goggles do not fog up during use, effectively protecting the user's eye health and providing a clear and wide field of vision.

[0010] A type of fog-free swimming goggles for sports. These goggles prevent fogging, allowing swimmers to clearly see everything within their field of vision throughout the swim. The fog-free principle utilizes hollow insulation technology to prevent fogging.

[0011] Figure 1 This describes the specific details of the fog-free swimming goggles proposed according to the present invention.

[0012] The fog-free swimming goggles consist of a lens (1) and a lens (2) forming a sealed air frame (3). The air frame (3) is a completely enclosed hollow space that is completely isolated from the outside world. The manufacturing method of the air frame (3) is to first injection mold a whole lens (1), and then embed the lens (2) into the elliptical step reserved in the lens (1) to form a space (3).

Claims

1. A fog-free swimming goggle, the fog-free swimming goggle is composed of a lens (1) and a lens (2) forming a sealed air frame (3), the air frame (3) being a completely closed hollow space isolated from the outside world.
