Glasses – Lenses

Our highly qualified and experienced dispensing Opticians at Silverman Opticians in London N1 provide detailed unbiased advice on spectacle lenses without obligation or pressure. As well as cosmetic factors, it is extremely important to consider vocational requirements when selecting lenses and coatings. It is also important to consider the best materials (refractive index) to ensure sufficient strength e.g. in rimless and semi-rimless (supra) frames and for high spectacle prescriptions, additional factors need to be considered in lens thickness calculations.

Essilor Eye Code – with Visioffice

At Silverman Opticians we have a special Visi-Office machine to order lenses with ‘Eye code’. Eyecode is a unique breakthrough in lens personalisation and is at the forefront of innovation. The dynamic 3D measurements, which can only be measured by Essilor’s Visioffice system, pinpoint the exact Eye Rotation Centre that is independent from head posture and unique to every person. Lens centering is more accurate, as for the first time both the Pupil distance (Pd) and the fitting height (Fh) are related to the ERC position. Patients will benefit from:

  • Lenses that are five times more precise, giving a total lens-to-eye synergy,
  • Instant vision without effort
  • Dynamic and highly contrasted vision

Single Vision Lenses
Advanced aspheric technology together with a wide range of high index materials allows for incredibly thin and flat lenses that no longer ‘bulge’ from frames. Therefore the choice of frames available is not restricted by the strength of your prescription.

Bifocal Lenses
Bifocal lenses are designed to counter presbyopia, which usually begins to affect us in our forties. As our eyes mature, the nearest point that we can focus on becomes further away and so reading and other near vision activities become more difficult. Bifocal lenses combine a distance and reading prescription in a single lens. The reading prescription is visible in a segment at the bottom of the lens.

Progressive Lenses (Varifocals)
Progressive lenses correct the effects of presbyopia with a gradual change in prescription from distance to near vision, restoring your natural vision without the unsightly segmentation lines or image jumps experienced with bifocals. The latest progressive lenses provide complete focussing freedom in all the visual zones to make your vision as simple and natural as possible.

Lens Coatings
Lenses can be uncoated, hard coated (so that they scratch less easily) or multi coated to minimise reflections from the lens surfaces. The latest combination coatings leave the lenses cleaner, tougher and clearer than ever before allowing people to see your eyes rather than your lenses.

Transitions
Transitions lenses offer all the benefits of clear lenses indoors and sunglasses outdoors. They provide visual comfort by automatically adjusting to changing light conditions. This helps to reduce glare and eye fatigue. Eye health is also preserved because these lenses block 100% of UV rays.

Sports Lenses
Special tints can improve the contrast of a ball against its background or reduce the glare from water or snow. Light weight, wrap around frames with ‘extra tough’ prescription lenses can offer excellent vision and protection. Masks and goggles can be specially made to incorporate your prescription.
