Spectacle Lenses

Ophthalmic lenses

The design (or ophthalmic surface) is the main element of an ophthalmic lens. Convergent, concave or progressive, a lens corrects various visual disorders by correcting the angle of light perception.

At Zeidan Eyecare centre, only the very best and premium lenses are used in glazing. Our glazing Laboratory in Leicester, ensures that all lenses meet the exact requirements of the wearer. Ophthalmic lenses are a very important part of your eye protection. Ensuring you have the very best lenses is by all means not an extravagant way, it is the best investment you can make to protect the precious sight- after all you can replace any part in your body with a transplant, but you can never transplant the retina or the optic disc- so why gamble with your vision?

High-Energy Visible Light (HEV light)/Blue Light

Some of the latest eye research has implicated HEV light – high-energy visible light in the violet/blue spectrum – as a contributor to the development of cataracts, macular degeneration and other serious eye maladies. HEV falls into the near-UV range, from almost 400 to over 500 nm in the visible spectrum. Blue light, roughly between 440 and 490 nm within the HEV spectrum, can damage the retina over time, leading to macular degeneration. The retina is the ocular membrane where images are formed and transmitted to the brain; the macula, the area of sharpest vision located near the centre of the retina, is the most likely area to be damaged. Macular Degeneration is the most likely cause of blindness in the World.

Photochromic Lenses Keep It Light

Photochromic lenses are perfect for patients who don’t want to switch from glasses to sunglasses, or for those who spend a lot of time outdoors. The lenses darken in the sunlight, and fade indoors.
For example, the new Transitions VI (Transitions Optical), the latest generation of Transition lenses, darken quickly outdoors in any temperature, and fade back to clear more quickly indoors as well, says the company. These lenses block 100% of both UV-A and UV-B rays and provide UV 400 protection.

AR Lenses Clear Up Confusion

Lenses that are not anti-reflective may allow halos or ghost images to interfere with your patients’ vision. When it comes to situations such as night time driving or working at a computer, these reflections can be distracting. But, anti-reflective (AR) lenses help to clear these problems up. If face time is a major component of your patients career, if they drive often at night time, or if they spend long hours in front of a computer monitor, AR lenses may help these patients both see better and feel better about how they look, because the visibility of the lens is reduced.

For example, the Teflon Clear Coat Lens (Carl Zeiss Meditec) is designed to deliver clear, crisp vision through lenses that feature high rates of scratch resistance and a hydrophobic topcoat.

Polarized Lenses Sharpen Any Situation

Polarized lenses are great for outdoor use, they reduce glare, enhance colours, and block UV rays. For patients who spend time in the great outdoors, these lenses can be very valuable. For example, the newly-released Xperio lens (Essilor of America) blocks 100% of both UV-A and UV-B rays, provides superior glare reduction and colour enhancement, and resists scratching, says the company. These lenses can improve contrast sensitivity by as much as 75%, and the Xperio gray lens allows for natural colour enhancement outdoors microsoft office 2008 for mac special media edition corel wordperfect office x4 standard oem microsoft office visio professional 2007 product key microsoft office 2007 professional apple final cut express 4 mac microsoft office visio 2003 adobe flash download autodesk autocad 2010 adobe creative suite 4 production premium intuit quickbooks 2010 for mac reviews microsoft visual studio 2008 shell microsoft office visio 2010 microsoft office visio professional 2003 intuit quicken rental windows 7 home premium intuit quickbooks 2010 for mac reviews buy microsoft office student corel wordperfect office x4 windows 7 cyberlink powerdirector free download microsoft works 9 product key buy microsoft money 2009 adobe acrobat 9 pro extended mac adobe illustrator download

Hi-Index Lenses Slimming Down!
A hi-index lens is great for those patients with high prescriptions rather than offer the patient a pair of frames with thick lenses, the hi-index lens allows you to incorporate a strong prescription into a thin, lightweight lens that allows the patient to wear nearly any frame he or she chooses.

For example, the Hoya EYNOA 1.67 lens features a monomer structure that allows the lens to be thin, flat, durable and light, with significantly less magnification and distortion than patients expect from a lens with a strong prescription.

Progressive Lenses Make it Smooth

Progressive lenses help presbyopic patients focus at different distances from near zones for reading, to intermediate zones for computer work to distance zones for driving, progressive lenses have a big job to do, and each pair of lenses has be to be carefully made for each patient.

For example, the Autograph II family of lenses from Shamir includes five lifestyle designs to fit a range of patients. And, these frames have a fitting height as little as 11mm, so the patients need for a multifocal lens won’t inhibit his or her frame choice. Also, the lenses feature Shamirs As Worn Technology, which takes three measurements to match the prescription to the patient and his or her wearing preferences exactly: vertex distance, pantoscopic tilt and panoramic angle.

Bringing Tomorrow into Focus

In the pipeline is the dynamic electronic focusing eyeglass, by Pixel Optics. Currently, the glasses are in limited, controlled wearer trials. The eyeglasses use no moving parts to focus between distances and near, says the company.
Currently, the company’s first static composite lens, At Last! is on the market. If all goes well with trials, the company hopes for a 2010 launch.
