  • câu hỏi: What are the commonly used distances for testing visual acuity with this chart?

    trả lời: The standard distances for testing visual acuity with the Snellen LED Visual Acuity Chart are typically 20 feet (6 meters) or 10 feet (3 meters).

KASHSURG Eye Charts Editorial Review

The Snellen LED Visual Acuity Chart 18.5 is an all-in-one unit with a table stand, wall hanging, and remote control for easy use. It includes optotypes that are easy to set at any reading distance with the option to set between 2.5 to 6 ft. The monitor has built-in features that do not require a computer, and it can display recorded data through a USB connection. However, it is not suitable for measuring contrast sensitivity and providing parameters other than visual acuity. The product receives mixed reviews from customers. While some are happy with the quality and performance of the chart, others complain about the lack of support for the product and the lengthy boot-up process after a power interruption. One user warns that the item stopped functioning correctly after less than a year of use and does not recommend purchasing it due to poor support.
