Abstract

The utility model relates to a vision-strengthening protecting lens, composed of an ordinary optical spectacle lens (1), a titanium dioxide plated film (2) and a zirconium dioxide plated film (3). The thickness of the film is 800 to 1100 angstroms. The utility model causes a driver for a motor vehicle to see things clearly in a strong light environment (daylight, vehicle lamp light and snow light) or a weak light environment (female, rain, fog days and nighttime), thus avoiding traffic accidents. The utility model is a novel protective lens for an ordinary person.

Description

Vission-strengthening protecting lens

This utility model is that a kind of increasing looks the safety goggles sheet.

In order to make motor vehicle driver under high light or low light environment, see object clearly, avoid accident, the lens that development is suitable for is very necessary." the safe driving lens " that China's patent 91212649.3 is provided, materials such as SnO2 and SiO-NiO or MgF2 are plated on the common eyeglass, form two layers of composite film coating, existing " dazzling Xiao decays " function, have again " to increase and look " ability in the low light level, not less than being a kind of novel glasses.But still can not eliminate the blind phase in vision wink since to blue, purple, the green glow reflectance is too high, influences the resolution that scenic focal point is looked for, MgF2 belongs to mantle, and is firm inadequately.

The purpose of this utility model is to adopt new film system, makes to be applicable to that motor vehicle driver sees object clearly under the high light or the low light level, has both eliminated the blind phase in vision wink, can differentiate the multi-functional glasses sheet of scenery color again.

The technical solution of the utility model:

Alternately plate titanium dioxide film and zirconium dioxide film on the ordinary optical lens, wherein the titanium dioxide plating is three layers, two layers of zirconium dioxide platings, the thick 800-1100 dust that is of each tunic.

Main feature of the present utility model and effect:

1, this film system is to all filterings of ultraviolet light, reflectance to purple light, blue streak reaches 70%, absorbance to green glow, gold-tinted and orange-colored light also reaches about 70%, has significantly reduced the stimulation of high light (daylight, car light light) to human eye like this, and has eliminated the blind phase in vision wink.

2, this film system is owing to visible light partial reflections selectively such as purple light, blue streak, green glow, gold-tinted, HONGGUANG, make human eye can normally differentiate scenery color (comprising the identification to red, green, yellow traffic light color).

3, this film system reflects snow light effectively, can eliminate snow blindness.

4, whole film is wear-resisting, corrosion-resistant, and is therefore durable.

5, the transillumination of this film system is dark brown, makes us feeling comfortable, can be the ordinary people a kind of ideal novel protected glasses are provided, as computer operation person's protective glass.

6, this eyeglass improves the visibility in the moon, rain, mist, snow sky.

Accompanying drawing is a lens section structure sketch map:

1 ,-ordinary optical glass eye eyeglass;

2 ,-titanium dioxide film;

3 ,-the zirconium dioxide film.

Embodiment 1: go up plated film at ordinary optical glass eye eyeglass (1), and ground floor plating titanium dioxide (2), second layer plating zirconium dioxide (3), alternate plating in this order, titanium dioxide film plates three layers altogether, two layers of zirconium dioxide film platings.Every layer of coating film thickness is the 800-1000 dust, and can add protective film coating.

Claims

A kind of increasing looks the safety goggles sheet, is made up of ordinary optical lens (1) and multilamellar inorganic dielectric film system (2), (3), it is characterized in that alternately plating on eyeglass titanium dioxide film and zirconium dioxide film, forms assembly of thin films, and each thicknesses of layers is the 800-1100 dust.
