Description
Technical field
The present invention relates to a kind of visual function method of testing, particularly about a kind of may be used for carrying out in Healthy Youth volunteer simulating age-related cataract cause dysopia state based on the visual function method of testing of covering glasses.
Background technology
Age-related cataract is modal old illness in eye, and its Main Morphology changes into insoluble protein content in crystalline lens its colour changed into yellow and crystalline lens that the increase of lens nucleus density causes, and to increase the cortex caused muddy.The change of crystalline lens color makes crystalline lens increase the some light filtration rate in visible ray, and cortex muddiness then causes crystalline lens to the uniform barrier effect of visible ray.The different phase of this disease will cause visual disorder in various degree, and then reduce the activity of daily living of the elderly, needs, on the basis of assessment lenticular opacities degree, tentatively judge that phacoscotasmus also proposes to improve the possible measure (such as: raising ambient lighting degree or suggestion are treated surgically) of its viability to the influence degree of life of elderly person ability.
Because the elderly suffers from whole body system disease more, it is directly carried out about the constitution test of viability exists many potential risks.Therefore, it may be necessary the dysopia state of covering glasses simulation lens ages and causing, and function assessment is carried out to it, inquire into the age-related cataract of the different order of severity to the influence degree of individual viability.What existing simulation age-related cataract caused dysopia state covers glasses, its analog form is simulate aging crystalline lens by the translucent occluding lens of milky evenly to block effect to each wavelength light, the filtration of aging crystalline lens to specific wavelength light cannot be simulated, and shield coverage cannot be quantitative, such covers the vision condition after glasses accurately cannot to control subject wears.
Summary of the invention
For the problems referred to above, the object of this invention is to provide a kind of can simulate simultaneously muddy crystalline lens to the filtration of light with block act on and screening effect can fixing quantity based on the visual function method of testing of covering glasses.
For achieving the above object, the present invention takes following technical scheme: a kind of visual function method of testing based on covering glasses, it is characterized in that comprising the following steps: 1) corresponding to given age feature the human lens of the elderly to the corresponding optical filter box of light penetration curve plotting in 380 ~ 750nm wavelength coverage, make the optical filtering curve of optical filter box and the human lens corresponding to the age characteristics of the elderly consistent to light therethrough rate curve in 380 ~ 750nm wavelength coverage; 2) the human lens cortex cloudy state corresponding to given age feature corresponding to the elderly is selected to cover pad pasting accordingly, covers pad pasting and selects the amblyopia of certain eyesight grade to constrain film; 3) select frame, and determine that the concrete size in region inlayed by the eyeglass of frame; 4) size of optical filter box is carried out cutting and eyeglass to inlay region and match, and size amblyopia being constrained film to carry out the optical filter box size after cutting size and cutting consistent; 5) two optical filter boxes are embedded in eyeglass respectively and inlay region, and the inside surface of shiny surface and respective filter assembly that each amblyopia is constrained film is pasted integral production and formed and cover glasses; 6) eye of eyeglasses-wearing Healthy Youth volunteer is covered by what be made, to healthy volunteer carry out simulating age-related cataract cause the function experiment of dysopia state, to the elderly of given age, the possible measure improving its viability can be proposed according to test findings.
Further, optical filter box described in each includes an optical filter and some optical thin films, described optical filter adopts optical quartz glass as base material, the outside surface of described base material is alternately coated with described optical thin film successively, makes the described optical filter optical filtering curve after plated film consistent to 380 ~ 750nm wave band internal transmission factor curve with years old human lens in 380 ~ 750nm wave band.
Further, the amblyopia that described covering pad pasting adopts thickness to be about 1mm constrains film pad pasting, and it is translucent frosted film that described amblyopia constrains film pad pasting; According to needs blurring in an image in various degree, described amblyopia is constrained film pad pasting eyesight grade and is comprised 10 grades, is specially: no light perception, light sensation, eyesight are less than 0.1, eyesight 0.1, eyesight 0.2, eyesight 0.3, eyesight 0.4, eyesight 0.6, eyesight 0.8 and eyesight 1.0.
Further, the framed structure that described frame adopts temple and picture frame to be integrated, wherein, the picture frame beam overall of described frame is 130mm, eyeglass mosaic area is wide is 47mm, and eyeglass mosaic area height is 30mm, and eyeglass mosaic area inward flange has the groove of width 3mm, temple length is 140mm, and temple scope of activities is respectively 8mm to the inside, laterally.
The present invention is owing to taking above technical scheme, it has the following advantages: 1, each eyeglass embedding region of frame of the present invention is embedded respectively and fixes an optical filter box matched with lens area, optical filter box is all form light penetration curve plotting in 380 ~ 750nm wavelength coverage according to years old human lens, and therefore the present invention may be used for simulating aging crystalline lens to the filtration of specific wavelength light and realizes muddy crystalline lens in simulation age-related cataract and specific wavelength light filtration rate is increased to the visual state caused.2, the inside surface of each optical filter box of the present invention pastes a covering pad pasting respectively, due to hide pad pasting to have evenly wavelength light each in visible spectrum and degree controlled block effect, therefore while in simulation age-related cataract, muddy crystalline lens blocks effect to uniform light, achieve controllability and the predictability of shield coverage, after wearing the occluding lens being pasted with this covering pad pasting, the amplitude of visual impairment can be predicted.3, there is adhering plastic adhesive film as covering pad pasting because the present invention adopts, therefore easily covering pad pasting can be attached at the inside surface of optical filter box, the shield coverage that achieving experimentally needs can change the object of the covering pad pasting with different shield coverage easily.4, the present invention is the mirror holder of integral type structure because employing material is soft medical silica-gel, temple and picture frame, this mirror holder has elasticity, temple inside and outside both sides mobility all can reach 8mm, therefore the facial shape of user is fully adapted to, applied widely, the needs of various tester can be met better.In sum, the present invention can be widely used in the various simulation age-related cataract carried out in healthy volunteer cause the function experiment of dysopia state.
