Functions
Uncorrected Visual Acuity (UCVA) Test
Uncorrected visual acuity, noted as UCVA, is the best possible vision that an eye can achieve without the use of glasses or contact lenses.

Best Corrected Visual Acuity (BCVA) Test
Best corrected visual acuity, noted as BCVA, is the best possible vision that an eye can achieve with the use of glasses or contact lenses.

Low Vision and Amblyopia Test

Refraction Test

Astigmatism Test

Power of Accommodation Test

The ability of the eye to adjust its focal length is known as accommodation. A healty eye is able to bring both distant objects and nearby objects into focus without the need for corrective lenses. That is, the healthy eye is able to assume both a small and a large focal length; It would have the ability to view objects with a large variation in distance. The maximum variation in the power of the eye is called the power of accommodation, which can be tested by CHE-S180.

Accommodation Training
Like any other group of muscle in the body, the cliary muscle can be exercised. They can regain flexibility and tone by correct exercises. The continuous use of CHE-S180 will provide a ciliary muscle-stretching effect, leading to an improvement in visual acuity.
