low-vision glasses

Abstract

A low-vision eyewear eyeshade comprises an eyeshade body. An outer exhaust hole is arranged on the outer side of the upper portion of the eyeshade body, inner exhaust holes are arranged on inner walls on two sides of the upper end of the eyeshade body respectively, the outer exhaust hole and the inner exhaust holes are connected through an exhaust passage, an outer air inlet is arranged on the outer side of the lower portion of the eyeshade body, inner air inlets are arranged on inner walls on two sides of the lower portion of the eyeshade body respectively, the outer air inlet and the inner air inlets are connected through an air incoming passage, and tiny particles are arranged on the inner wall and the left-side outer surface of the eyeshade body and regularly distributed in an array-shaped manner. Consequently, air inside the whole eyeshade is permanently in a flowing state, so that a user wearing eyewear cannot feel stuffy and tight when the low-vision eyewear eyeshade is in use, water vapour cannot appear on the low-vision eyewear to influence visual effect, and outside stray light can be blocked well.

Description

technical field [0001] The invention relates to an eye mask, in particular to an eye mask for low vision glasses. Background technique [0002] Ordinary goggles are airtight to block external stray light, but the eyes are constantly dissipating heat and breathing, so that the generated water vapor blurs the image observed by the wearer, and makes the patient's eyes very easy to fatigue and very painful. Uncomfortable, and if you directly open holes on the eye mask for ventilation, the external stray light will directly enter the user's eyes, and it will not be able to block the stray light from entering the user's eyes; and the inner wall of the eye mask is either too smooth or It is too rough to play the role of extinction of internally reflected stray light. The light emitted by the vision aid irradiates the inner wall of the eye mask and then reflects one or more times into the user's eyes, which will seriously interfere with the user's observation effect; general eye mas...

[0002] Ordinary goggles are airtight to block external stray light, but the eyes are constantly dissipating heat and breathing, so that the generated water vapor blurs the image observed by the wearer, and makes the patient's eyes very easy to fatigue and very painful. Uncomfortable, and if you directly open holes on the eye mask for ventilation, the external stray light will directly enter the user's eyes, and it will not be able to block the stray light from entering the user's eyes; and the inner wall of the eye mask is either too smooth or It is too rough to play the role of extinction of internally reflected stray light. The light emitted by the vision aid irradiates the inner wall of the eye mask and then reflects one or more times into the user's eyes, which will seriously interfere with the user's observation effect; general eye masks The contact surface of the eye contact part is designed to be smooth for shading and sealing, which leads to the formation of vacuum bonding between the eye skin and the contact surface of the eye mask, making the user uncomfortable
