Driving Varifocal Thin & Lite High Definition Lenses - Crystal Vision

This prescription lens package will be fitted into your chosen eyewear and quality control checked by Eyekit prior to dispatch to ensure the quality and accuracy of your prescription. It comprises the following as summarised in the title:

Driving Varifocals - These personalised progressive lenses incorporate a power distribution across the lens specifically adapted for driving. Most driving time is spent looking ahead, which requires wide, clear visual fields. However, the eyes also have to shift quickly between different viewing distances with minimal head movements: from the road to the navigation device, from the mirrors to the dashboard. Focusing and refocusing can be especially challenging for mature drivers. Driving varifocal lenses provides maximised distance and intermediate zones and a smaller near zone. They also incorporate a night vision zone for greater visual quality and less fatigue when driving at night. Many general varifocal lenses by contrast can make it uncomfortable to drive having an inadequate distance visual field or limited peripheral vision.

Thin & Lite Lenses These 'Thin & Lite' lenses are thinner and lighter than our standard 'Lifestyle' prescription lenses. They reduce the edge thickness in minus prescriptions and the centre thickness in plus prescriptions. This makes the lenses thinner and lighter to wear for both types of prescriptions while maintaining their optical performance. Recommended for prescriptions where your prescription is between 2 and 4 spheres.

High Definition - The High Definition Varifocal lenses are the best and latest lens designs on the market today. They offer all the advantages of the Performance lenses but are optimised in such a way that they provides a wider distance, intermediate and near area.

They use the latest free-form technology, 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 standard 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.

Crystal Vision - These lenses include our 'Crystal Vision' coatings. A multi-layer anti-reflective coating on both sides of the lens with hydrophobic top coat applied over a hard coat to give excellent visual performance and durability. 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.

Specification:

• Lens Type: Hoya.There are two options:

  • EnRoute- Developed by Hoya to meet the visual demands of today's drivers, EnRoute lenses are equipped with a specially developed Glare Filter. This specifically cuts light in the blue spectrum, significantly reducing light scatter and distracting glare from the dashboard, streetlights and LED and Xenon headlights from oncoming traffic. At the same time, it enhances the transmittance of necessary light, improving contrast and brightness perception, even in poor light and bad weather. The result is more comfortable, relaxed vision even in stressful driving situations.
  • EnRoute Pro- Offers all the benefits of Enroute and adds:
  • A contrast-enhancing filter for improved contrast and colour perception, and even better glare reduction.
  • A lens design that features integrated Double Surface Technology and Balance View Control for stable image perception, clear vision at the far distance, the dashboard and in mirrors and easy switching between them for a natural, relaxed driving posture.
• Index - 1.6. (The higher the index, the thinner and lighter the lenses).
• Abbe - 41.(The higher the abbe value, the better the optical clarity of the lens).
• Density - 1.3g/cm cubed.
• UV Protection - 395nm.
• Prescription Range: +6.00 to - 8.00 Spheres with opposite cyls to 4.00. Higher powered prescriptions are available for certain styles. If needed, please contact us to check availability.

Options available:

• Single Vision
• Mirror options - Gunmetal, Blue Mirror, Green Mirror, Copper, Silver, Gold.
