Driving Varifocal Lifestyle Performance Lenses - PhotoPolar Crystal Drive

Lifestyle Lenses   These lenses are made from high quality CR39 resin which is the most common optical material for prescription glasses today. They provide very little distortion and are lighter and thinner than glass making them comfortable to wear. They are not recommended for impact sports/work environments as they can break.

Performance - These are high definition (HD) varifocal lenses use the latest free-form technology. They use a digital design process that gives lens designers the ability to reduce lens aberrations even more than they can using conventional lens design and processing techniques with the Premium option. Lighter and thinner than standard lenses they provide exceptional night/low light vision reducing glare and halo effects from car headlights. They also offer exceptional contrast perception sharpening vision and improved colour rendition providing brighter and more intense colours. This is particularly important for varifocals and highly curved lenses as it ensures they provide the best vision across the whole curvature of the lens avoiding optical distortions that can occur in the periphery area of vision.

PhotoPolar - There are three options to choose from dependent on your requirement:

1. Infinite Grey Lenses - NuPolar Infinite Grey are a new generation of prescription sun-wear products. They combine the award winning NuPolar polarisation technology with state of the art photochromic. NuPolar Infinite Grey offers the widest range of light transmittance while maintaining 99% polarisation efficiency. In its lightest state, it has 40% light transmittance providing great vision in overcast weather or even indoors. When fully activated, lens transmittance goes down to the lowest permissible level for driving reaching 9%, great for bright sunny days.

• Lens Category – Cat. 2 to 3. With a visible light transmission of 40% to 9%, they are ideal for wearing in bright cloudy to sunny days.
• Tint Colour - Grey

2. DriveWear Lenses - These are made from advanced Transitions photochromic technology and breakthroughs in NuPolar polarising technology. The photochromic lens which get darker or lighter in accordance with the intensity of visible light has been specially developed to work effectively behind car windshields. These DriveWear lenses are capable of sensing and reacting to varying light conditions both outside and behind the windshield of the car or aeroplane canopy. The polarising lens will eliminate glare from all reflective surfaces such as the road surface or other cars. Unlike other polarising lenses they have been developed to work across the photochromic range of the lens.

• Lens Category – Cat. 2 to 3. With a visible light transmission of 35% to 12%, they are ideal for wearing in bright cloudy to sunny days.
• Tint Colour - Amber

3. Transitions XTRActive Polarised Lenses - Made from advanced Transitions photochromic technology and breakthroughs in variable polarising technology. They are light reactive lenses that changes lens tint density with the changing light conditions providing comfortable vision whatever the light intensity. 

• Indoors - Lenses are clear with a hint of tint to provide extra protection from harsh blue light.
• Behind the windshield of the car - Lenses darken to protect eyes from sunlight while driving. However, polarisation is not active.
• Outdoors - Uniquely designed to darken according to the amount of light. The XTRActive dyes enable the lens to reach its darkest state inwhen the lens is at its darkest state. brightest light conditions.
• Blinding glare conditions - Variable polarisation activates in bright outdoor conditions reaching a maximum of 90% polarisation efficiency when the lens is at its darkest state.
• Lens Category Cat. 0 to 3. With a visible light transmission of clear to 12%, they are ideal for wearing in very low light conditions such as experienced in rain and fog to partially cloudy/sunny days. Ideal for wearers who require clear lenses indoors and at night that provide comfort and convenience by darkening outdoors dependent on the light conditions.
• Tint Colour - Grey

Crystal Drive - Specifically designed for those who drive, offering improved comfort in all driving conditions with improved comfort during the day and night. The lens coating offers the highest transmission across the visible spectrum but does reduce the overall amount of blue light entering the eye.There is a slight filter to achieve this but the lens still remains almost clear. Key benefits:

• Scratch Resistant Coating - Reduces scratching and abrasions over time, keeping the lens clearer for longer and maximising vision quality and useful life of the lens over non coated lenses.
• Anti-reflective Coating - Prevents those annoying reflections, eliminating interference glare and ghost images, reducing eye strain and improves vision.
• Hydrophobic Coating - This water repellent coating is similar to a wax coating on a car, it helps to shed water droplets and avoids smudging. Also, water is not attracted to the lens surface in humid conditions (steam, condensation etc). Ideal for outdoor use such as playing football on rainy days or for spray when sailing.
• Blue Light Filter - Reduces eye fatigue and eye strain from light reflections during the day and car headlights at night. It keeps the eyes in better condition, offering more comfortable and relaxed vision and a better contrast perception while driving.

Prescription strength of up to a combined maximum power of +6.00 to -8.00. That is the combined power of your sphere and cylinders together must not be more that +6.50 to -8.00 for this frame.
