Experiment device used for refraction development action of light on eyeballs

Abstract

The invention relates to a device used for researching refraction development action of light on eyeballs. The experiment device comprises a voltage regulator, an electronic timing switch, an outer support and a cage. The voltage regulator is connected with the electronic timing switch, and the cage is located in the outer support. The outer support comprises a top plate, a bottom plate, a left side plate, a right side plate, a front side plate and a rear side plate. A transparent drawer type partition board is arranged between LED lamp tubes on the bottom plate and the cage. The partition board is provided with a water inlet and a discharge opening. The left side plate, the right side plate and the front side plate are each provided with an observation hole. The observation holes are rectangular. One side of each observation hole is provided with a curtain pulling rod. The curtain pulling rods are connected with a curtain. White reflective films and the LED lamp tubes are arranged on the inner wall of the top plate, the inner wall of the bottom plate, the inner wall of the left side plate, the inner wall of the right side plate, the inner wall of the front side plate and the inner wall of the rear side plate. The device has the advantages that different light intensities and spectra can be set, light intensity in a breeding space is uniform, and the device is suitable for systematic research and observation of actions of light on refraction development of the eyeballs.

Description

technical field [0001] The invention relates to the technical field of animal experimental devices, in particular to an experimental device for studying the effect of light on the development of eyeball refraction. Background technique [0002] The growth of the eyeball is not only regulated by the common development mechanism that governs various organs of the whole body, but also can coordinate the development of various parts of the refractive media through self-regulation. Studies have shown that eyeball self-regulation depends on the input of visual information. [0003] Visual information plays an important role in both normal and abnormal refractive development, and experimental animals from different species can provide evidence to prove the correctness of this conclusion. The classic research includes the interference of imaging to make the retinal image blurred or unable to image, thereby significantly accelerating the growth of the eye axis and causing myopic ame...

Problems solved by technology

However, there is no ready-made animal breeding device in the existing experimental equipment that can be directly used for light experiment research

[0005] Related animal breeding cages for this lighting experiment are currently unavailable on the market

The purchased animal breeding equipment is only suitable for the daily feeding of animals. Animals are kept under natural light or ordinary indoor fluorescent lamps. Different settings for the lighting environment (including spectrum and light intensity) cannot be made, and the light intensity in the cage cannot be guaranteed. Uniformity and consistency of light from cage to cage

[0006] To sum up, there is an urgent need for an experimental device that can set different spectra, different light intensities, and uniform light intensity for studying the effect of light on the refractive development of the eyeball. Not yet reported
