Abstract

The utility model belongs to lens design technical field, in particular to a kind of to avoid the eyeglass that the eyes are affected by the sunlight, it is in structure, the lateral surface of substrate or medial surface upper middle lower part region are provided with clear anti-fog layer, upper area is covered with transparent frosted layer, this makes the upper area of eyeglass thicken, and the sunlight at this is made to be broken up, be weakened, this direct projection of part light to eyes is avoided, the degree that the eyes are affected by the sunlight is greatly reduced.

Description

It is a kind of to avoid the eyeglass that the eyes are affected by the sunlight

Technical field

The utility model belongs to lens design technical field, in particular to a kind of to avoid the eyeglass that the eyes are affected by the sunlight.

Background technique

When weather clears up, outdoor sunlight is often very dazzling, although colourless eyeglass can ensure that the clear of the wearer visual field Degree, but do not have the effect for blocking, weakening strong light.People can also select wear dark glasses when outgoing, but sunglasses will affect wearer Sight often will appear biggish blind area at the moment especially when people are from light area just entry of backlight region, this Very big hidden trouble of traffic can be brought.In addition, having on sunglasses is not easy the case where seeing proximal end clearly, need to have a look during such as cycling Wrist-watch can not just be seen clearly immediately.

Utility model content

In order to solve the above technical problems, the utility model provide it is a kind of avoid the eyeglass that the eyes are affected by the sunlight, including transparent Bare substrate, layer of transparent anti-fog layer is provided on the lateral surface or medial surface of substrate, and clear anti-fog layer covers on the outside of substrate The middle lower zone of face or medial surface,

As preferred: clear anti-fog layer overlay area accounts for 3/4ths of substrate lateral surface or medial surface size；

As preferred: being covered on the substrate lateral surface or medial surface of clear anti-fog layer, remaining area in addition to clear anti-fog floor Domain is all covered with transparent frosted layer, and transparent frosted layer is equal with the thickness of clear anti-fog layer.

Detailed description of the invention

Fig. 1 is the schematic diagram of a layer structure that the eyeglass that the eyes are affected by the sunlight is avoided in the utility model,

Fig. 2 is in the eyeglass of this programme, clear anti-fog layer in the distribution schematic diagram on substrate lateral surface or medial surface,

Wherein, 1-substrate, 2-clear anti-fog layers, 3-transparent frosted layers.

Specific embodiment

It should be noted that word "upper", "lower" used in the description of the utility model refer to the direction in attached drawing 1 (in attached drawing 1 placement status of eyeglass this be also eyeglass when actual wear uses general state), word "inner" and "outside" point It does not refer to towards or away from the direction of (when lenses fitted) eyes.These are merely for convenience of description the utility model and simplification Description.

As shown in Fig. 1, the eyeglass that the eyes are affected by the sunlight that avoids of the utility model includes transparent blank in structure first Substrate 1, the substrate 1 are manufactured by CR-39 resin material, and clear anti-fog layer 2, clear anti-fog layer are covered on the lateral surface of substrate 1 2 cover the middle and lower part region on 1 lateral surface of substrate, and account for 3/4ths (such as attached drawings 2) of 1 lateral surface size of substrate,

On the lateral surface of substrate 1 in addition to clear anti-fog layer 2, remaining region is all covered with transparent frosted layer 3, transparent frosted layer 3 is equal with thickness of the clear anti-fog layer 2 on 1 lateral surface of substrate.

It is above-mentioned to avoid the eyeglass that the eyes are affected by the sunlight during the preparation process, first by the top of 1 lateral surface of CR-39 resin substrate (with film) shelters from, then forms clear anti-fog layer 2 to the exposed region plating in 1 lateral surface lower part of substrate；Then (using thin Film) clear anti-fog layer 2 is sheltered from just, and remove and blocked at 1 lateral surface top of substrate, to the upper of 1 lateral surface of substrate Portion's plating forms transparent frosted layer 3.

Applicant's plating on the lateral surface of substrate 1 forms clear anti-fog layer 2, is covered with the region energy of clear anti-fog layer 2 The clarity for keeping glasses for a long time avoids glasses from hazing and thickens, but the clear anti-fog layer 2 of this programme only covers mirror The middle and lower part of piece, and eyeglass top is without this functional layer,

This is because get off in view of sunlight is substantially from the angular illumination of oblique upper, direct arrival wearer's eyes Part sunlight be when passing through eyeglass the eyeglass walked top, therefore not in the position plating clear anti-fog layer in this programme 2, in order that the position on eyeglass is allowed to haze to thicken, so that the sunlight at this broken up, weakened, avoid this Direct projection of the part light to eyes, greatly reduces the degree that the eyes are affected by the sunlight,

Further, it is possible that there is the region that fuzzy region is limited only to eyeglass lateral surface top 1/4, and eyeglass middle and lower part For blank transparent region, and it is covered with clear anti-fog layer 2, will not influence sight；And due to being not directed to ink in entire eyeglass The material of mirror, therefore from the confusion region on eyeglass top to the clear area of middle and lower part, wearer can smoothly mistakes on visual perception Degree, is unlikely to the situation for occurring flickering or hazy.

Further, in order to ensure eyeglass top has light-dispersing effect, this programme forms transparent frosted in the region plating Layer 3, transparent frosted layer 3 is equal with the thickness of clear anti-fog layer 2 of middle and lower part, and this guarantees eyeglass in appearance regular Property.
