Introduction

The widespread use of various electronic visual display terminal products and LED lighting products not only bring convenience to people, but also cause The problem of visual fatigue seriously affects the physical and mental health of users, causing problems such as reduced sensitivity to light and decreased adjustment ability, which affects to varying degrees. It affects people's visual perception function, and even leads to decreased vision. At present, the problem of decreased visual perception caused by the use of visual display or lighting products The lack of unified and standardized test methods and standards affects the healthy development of the industry. The formulation of this document provides various visual displays for relevant departments Or a quantitative measurement method of the impact of lighting products on the main visual perception functions of the human eye, aiming to standardize test methods, reduce production costs, and promote industry healthy growth. According to the impact of different types of electronic visual display terminal products and lighting products such as LEDs on users' visual fatigue, GB/T 40230 The visual fatigue test is divided into four aspects. optics, visual perception, cognitive function, and other functions, and finally based on different evaluations The evaluation results of the aspects give a comprehensive evaluation, which is to be composed of five parts. ---Part 1.Optometry. The purpose is to introduce the long-term use of different types of electronic visual display or lighting products to users A test method that affects performance in terms of vision. ---Part 2.Visual perception function. The purpose is to introduce the long-term use of different types of electronic visual display or lighting products. A test method for impaired visual perception of households that affects performance. ---Part 3.Cognitive function. The purpose is to introduce the long-term use of different types of electronic visual display or lighting products to users Methods of testing the effects of cognitive decline. ---Part 4.Other functions. The purpose is to introduce the long-term use of different types of electronic visual display or lighting products to users Emotional, social function and biological rhythm test methods. ---Part 5.Comprehensive evaluation. The purpose is to perform multi-dimensional fusion calculations on the results of different evaluation methods, and finally give different electronic The overall situation of the impact of visual display or lighting products on the eyestrain of users. Asthenopia test and evaluation method Part 2.visual perception function

1 Scope

This document specifies the visual perception function test methods and related technical requirements for visual fatigue. This document is applicable to the visual perception function caused by long-term use of display products or lighting products by users in various places such as work and life. The visual fatigue test of the influence of the face. This document does not apply to the measurement of the photobiological safety impact of display or lighting products on people.
