Description
Technical field
This utility model relates to a kind of astigmatic chart combination optometry case.
Background technology
Current optician's shop generally adopts artificial inserted sheet optometry, strong optician's shop is equipped with comprehensive optometry instrument, first inserted sheet optometry is general understands refraction of eye character with rafractive, with crack sheet optometry or try eyeglass relative method on, tentatively determines this ball light and astigmatism degree.Comprehensive optometry instrument method is also first understand human eye dioptric character by computerized optometry, then by means of vision sighting target and astigmatic chart sighting target, tentatively determines this ball light and astigmatism degree.Above-mentioned two kinds of methods finally all by adopting the method for crossed cylinder lens, not only accurate adjustment axis of astigmatism, and will carry out accurate adjustment astigmatism degree with it.But when adopting crossed cylinder lens accurate adjustment astigmatism, it is the change that will have influence on ball luminosity number, namely often 1.00D astigmatism is increased, 0.50D ball light will be reduced, and the terminal of optometry is adjusted on the retina of human eye ball light focal plane and astigmatism focal plane simultaneously, due to the relatedness that crossed cylinder lens accurate adjustment astigmatism and ball light adjust, need by visual acuity chart and red green mark, repeatedly adjust astigmatism and the relation between ball light and retina, the object of final realization blur-free imaging on the retina, this process is more loaded down with trivial details, and have much relations with the experience of optometrist, be easy to occur optometry deviation.
Utility model content
It is simple that the technical problems to be solved in the utility model is to provide a kind of structure, uses, easy for installation, simple to operate, cost is low, precision is high, technical difficulty is low, easily grasps, and speed is fast, reliability is high, technological means is advanced, energy-conserving and environment-protective, control effects is good, applied widely, long service life, has the astigmatic chart combination optometry case of safe and reliable effect.
For solving the problem, this utility model adopts following technical scheme:
