Our highly qualified and experienced dispensing staff at Zacks London Eye Clinics (Islington, London N1 and Fitzrovia, London W1) provide detailed unbiased advice on single vision spectacle lenses without obligation or pressure.

Single Vision Lenses

Visual quality, cosmetic appearance and wearing comfort, i.e. weight, must all be taken into account in the design of single vision lenses. Nowadays, higher refractive indices for both plastic and glass lenses together with advanced aspheric / atoroidal surface designs make it possible to produce flat, light lenses which provide even patients requiring high prescriptions with outstanding visual and wearing comfort. At Zacks London Eye Clinics we supply incredibly thin and flat lenses that no longer ‘bulge’ from frames so that the choice of frames is not restricted by the strength of your prescription. We routinely scan patients' frames to provide a variety of lens thickness quotations from different suppliers and our lens menu includes premium and budget designs to suit all pockets.

Nikon

Nikon's new Bi-Aspheric 'Seemax' range of lenses are custom made to reduce aberrations and distortions that increase with high prescriptions providing excellent performance across the entire surface of the lens.

Essilor

Essilor has one of the most extensive catalogues with a wide range of stock and specially surfaced lenses in several materials to fit any budget and most spectacle prescriptions. Essilor lenses are available uncoated and with a variety of lens coatings including transitions.

Seiko

Seiko's AZ design is a ‘double aspheric’ lens meaning that both sides of the lens are manufactured with specially designed curves that provide very sharp vision. You may have noticed with your current spectacle lenses that images are distorted or blurred when you look out towards the edge of your frame, for example, when you reverse your car. This effect is largely removed with SEIKO AZ lenses. Apart from exceptionally clear vision, AZ design lenses look better and feel more comfortable than ordinary lenses. This unique lens design was created by SEIKO and provides the following benefits:

• Up to 50% thinner and 45% lighter than conventional plastic lenses
• Provide natural and comfortable vision with accurate image perception. Clearer than conventional plastic lenses due to minimal surface reflections
• Reduced magnification of the wearer's eyes
• Include excellent anti-reflection coatings on both sides of the lens resulting in excellent vision and more comfortable vision when driving at night
• Easy to clean due to the water and dirt repellent surface
• Available for most prescriptions
• Ideal for most frame fashions
