Light Transmission

What is Light Transmission?

The Light Transmission represents the amount of light that passes through a lens without being absorbed or reflected. It is a key parameter for assessing the optical quality of materials, coatings and tints.

• Percentage value — Indicates how much light reaches the eye.
• It depends on the material — Purity and refractive index affect transparency.
• It affects the visual output — It determines sharpness and the perception of detail.

Why it is important

• Sharpness — A good signal improves picture quality.
• Visual comfort — Reduces fatigue and perceptual instability.
• A luminous experience — It determines how natural the vision appears.
• Choosing lenses — Essential for selecting materials and treatments.

Factors influencing the Light Transmission

At Isolani Optical Centres, Light Transmission is taken into account when selecting lenses to ensure clear, stable and comfortable vision in all lighting conditions.

• Materials — Transparency and purity affect the amount of light transmitted.
• Anti-reflective coating — It reduces glare and increases the amount of usable light.
• Photochromic lenses — They adjust the transmission according to the light.
• Polarised lenses — Contrast and sharpness are improved when shooting 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 light management in every environment.

• 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 Light Transmission may vary depending on materials, treatments and conditions of use. At Isolani Optical Centres, we offer ongoing support with adjustments, non-medical check-ups and updates to your optical solutions where necessary, to ensure stable and comfortable vision over time.
