Contrast Sensitivity

What is Contrast Sensitivity?

Contrast Sensitivity measures how easily the eye can distinguish between objects that do not differ markedly in brightness. It is a different parameter from visual acuity, as it relates to the perception of detail in real-world conditions, not just in ideal situations.

• Details in low light — Essential in dimly lit environments.
• Perception of shapes — It helps to distinguish between outlines and surfaces.
• Dynamic vision — Important whilst on the move or in changing conditions.

Why it is important

• True visual quality — It affects our day-to-day perception more than visual acuity.
• Safety — Useful for driving, sport and dynamic activities.
• Comfort — Reduces eye strain and fatigue.
• Choosing lenses — Geometry and processing techniques can improve contrast.

Factors influencing Contrast Sensitivity

At Isolani Optical Centres, Contrast Sensitivity is taken into account when selecting lenses to ensure clear, stable and natural vision in all lighting conditions.

• Anti-reflective coating — Reduces glare and improves sharpness.
• Lens geometry — Optimise image quality.
• Materials — They affect transparency and visual rendering.
• Polarised lenses — They improve the contrast outdoors.

Isolani Experience

Each lens is designed with the frame, technical specifications and lifestyle in mind, to ensure an ideal balance between visual quality, comfort and the perception of detail in all lighting conditions.

• Bespoke glasses — Complete customisation of the frame and choice of lenses.
• Behavioural Centring — Real-world operating parameters for precise design.
• Simulation Room — Aesthetic and functional checks prior to production.

Ongoing support

The Contrast Sensitivity may vary depending on usage conditions and visual habits. At Isolani Optical Centres, we offer ongoing support through adjustments, non-medical checks and updates to your optical solutions whenever necessary, to ensure clear and comfortable vision over time.
