从Hong Kong供应商批发进口38plates Ishihara Test Book — FOB条款

The 38-plate Ishihara test book from Labwre Tech. Inc. is a clinical diagnostic instrument for detecting congenital colour vision deficiencies, specifically red-green colour blindness. This edition comprises 38 pseudoisochromatic plates, each printed with carefully controlled dot patterns that present numbers or pathways visible only to individuals with normal trichromatic vision. The plates follow the standard Ishihara protocol established in the early twentieth century and remain the most widely administered screening method for colour vision defects in ophthalmic practice worldwide.

Each plate is produced using high-resolution lithographic printing on matte art card to minimise surface glare and ensure consistent colour saturation under varied clinical lighting conditions. The standard plate dimensions are approximately 17 cm by 24 cm, bound in a hardcover portfolio to protect against warping and fading. Typical industry practice requires storage away from direct sunlight and fluorescent exposure to preserve plate integrity, with replacement recommended if colour shift becomes perceptible. The test is designed for screening rather than precise quantification of colour vision loss, so results should be corroborated with anomaloscope testing where diagnostic certainty is required.

Ophthalmology clinics, optometry practices, occupational health departments, and medical schools represent the primary buyers for this instrument. Regulatory and military recruitment bodies also maintain stocks for mandatory colour vision screening. When sourcing from Labwre Tech. Inc., buyers should confirm whether the supplied edition includes the standard 38 plates or any supplementary transformation plates, and verify that printing adheres to the original colour specifications rather than unauthorised reproductions. Packaging and shipping terms are not specified in the source data and must be confirmed directly with the supplier.
