Visual Acuity
Visual Acuity describes the ability to distinguish fine details and perceive shapes and contours clearly. It is a key parameter for assessing the quality of vision and the effectiveness of ophthalmic lenses.
What is Visual Acuity?
Visual Acuity refers to the eye’s ability to perceive details at a given distance. It is expressed in terms of values that indicate the level of sharpness achievable with or without lenses.
- Sharpness — Indicates how clearly the details are perceived.
- Contrast — It affects the ability to distinguish shapes and outlines.
- Perceptual stability — It helps maintain natural vision.
Why it is important
- Visual quality — Adequate visual acuity enables clear and distinct perception.
- Comfort — Reduces fatigue and perceptual instability.
- Choosing lenses — It guides the selection of materials, geometries and surface treatments.
- Evaluation of optical solutions — It allows you to compare different options.
