In the realm of eye health diagnostics, visual field testing is an essential method that offers a comprehensive analysis of a patient’s visual fields, covering a wide testing range. This test is critical for detecting any field loss that may indicate underlying eye conditions.

Key Aspects of Visual Field Testing:

  1. Blink Control and Eye Tracking: Modern visual field tests incorporate advanced eye tracking and blink control mechanisms. These features ensure the accuracy of test results by accounting for natural eye movements and blinks during the testing process.

  2. Kinetic Testing: This method involves moving objects at various speeds and trajectories across the patient’s field of vision to map and measure their visual field dynamically. Kinetic testing is vital for identifying peripheral vision issues that static tests might miss.

  3. Blue on Yellow Testing: Also known as short-wavelength automated perimetry, this testing method uses blue stimuli on a yellow background to detect certain types of vision loss earlier than standard white-on-white testing. This contrast is particularly useful for assessing conditions like glaucoma.

  4. Projection-Perimeter: This technique involves projecting points of light of varying intensities across different parts of the visual field. It is a traditional approach that continues to provide valuable insights into the extent and nature of visual field loss.

Visual field testing is not just about detecting problems; it’s an ongoing part of eye care that helps to monitor the progression of eye diseases and evaluate the effectiveness of ongoing treatments. Regular and precise visual field tests are indispensable for maintaining optimal eye health.


1. Rigorous implementation of Goldman international standard.

2. Halogen projection system: stimulation light source is from wide band visible spectrum, fully meet colored cone cell stimulation.

3. Accurate and elaborate database of normal population of all age groups, recognition of more subtle early visual field defects.

4. GHT glaucoma semi vision analysis, make glaucoma diagnosis easier.

5. GPA glaucoma progression analysis upgrade, slight glaucoma development is obvious.

6. Standard SWAP blue-yellow visual field examination, sensitive to earlier visual field defects.

7. Scientific and intelligent interactive inspection strategy, 30 degree range visual field inspection only takes 3 minutes.

8. Simple one-stop modular software design, equipment operation learning only 2 minutes.
