We are developing and manufacturing “Righton” Brand ophthalmic instruments for ophthalmologist of eye hospital & clinic and for optometrist in global market. ODM or OEM product supply are available not only product development and production in ISO13485 certified factory, but also obtaining medical device regulatory certification including MDR, MDSAP or FDA and global delivery service.
Proper eye refraction measurement is necessary to make eye glass or contact lens. We apply precise positioning focus technology for depth direction in addition to vertical/horizontal alignment detection for eye refraction measurement by objective refractometory instrument. For measurement of children, person on wheel chair or patients on the bed, our hand held type refractometer can be measured in equivalent measurement accuracy compare to conventional table type of refractometer.
Subjective optometry method is different in every country. Based on our own research of the optometry worldwide, we developed subjective instruments for usable by multiple optometry method. We also proposed eye glass prescription with combined technology of our unique accommodation microfluctuation analysis.
Handy type autorefractometer & keratometer Righton Retinomax Series is equipped with various ideal functions as handy device for precise measurement, user friendly light weight and longer time battery operation. Retinomax is our fundamental product with our unique downsizing and lightning technologies of global share Number 1 product.
Technology as retro observation for objective measurement instrument, on refraction measurement, the cloudiness in the eyeball optics system can be observed, and binarization of the opacity degrees and measurement of the opacity range. Stable measurement is possible for different eye condition or pupil size by our unique technology.
Normal eye condition
Retro illumination mode
Opaciy detected
PC, smartphone, digital devices force us to overuse our eyes. Crystal lens of human eyes are supported by ciliary muscle and slightly shaking to keep focus to see target. Ciliary muscle shrinks to give stress on crystal lens to see near distance, and relaxed to see far distance. Ciliary muscle slightly shaking measurement technology can be analyzed eye stress conditions which is impossible to diagnose by normal optometry.
Normal eye
Computer vision syndrome
Presbyopia
We apply advanced optical technology to develop slit lamp and aspherical lens for ophthalmologist and optometrist. We are keep developing lens design technology by microscope development, high resolution imaging technology for ophthalmology photo or high quality aspherical lens reducing aberration to the limit.
