Optimum Rx Lens Specialists: OptiPure+
OptiPure+ from Optimum Rx Lens Specialists is said to stand out among other coatings due to its innovative and unique formula, developed with the knowledge and expertise of a company with over 20 years as a coating specialist. With 99% light transmittance, OptiPure+ is said to offer unparalleled clarity and transparency, ensuring maximum acuity and superior aesthetics.
With enhanced hydrophobic and oleophobic properties thanks to unique ingredients, OptiPure+ coated lenses are also said to stay cleaner for longer, even in harsh environmental conditions. As well as improved water run-off and reduced fingerprint and perspiration smudging, an additional layer providing dust resistance has been included to ensure particles are not attracted to the lens during cleaning.
With the highest level of scratch resistance, OptiPure+ has been created to ensure the added value benefits do not deplete with age and wearers can expect the same performance from day one until their next eye exam. The coating is supplied with a two year no quibble guarantee.
Shamir: Shamir Glacier Expression 
According to Shamir, the latest innovation in the Shamir Glacier coating family, Shamir Glacier Expression, sets a new standard for everyday anti-reflection coatings. The product of extensive research and development, Shamir Glacier Expression is said to raise the bar by utilising a greater number of accurately calculated layers, while retaining a similar thickness and durability level.
This enables it to specifically regulate those light wavelengths that the human eye is most sensitive to and achieve enhanced control over reflectance. The result is said to be drastically minimised reflections, reduced obscurement of your eyes, and improved aesthetic appeal.
Glacier Expression is also said to provide improved contrast sensitivity and light transmittance for the clearest, sharpest possible vision. Superior contrast sensitivity translates to faster reaction times in daily activities, and can ultimately even improve vision while driving, especially at night.
Younger Optics: Claryo 1.74 
The dual aspheric surfaces of Claryo 1.74 lenses are said to be flatter and deliver the widest undistorted field of view for higher powers when compared with other thin lenses. Claryo reflection-free coatings comprise 11 layers, which Younger Optics says makes it the ultimate clear lens, thin film technology.
The seven-layer ion bombardment, anti-reflection coating is said to deliver 99.9% light transmission, which helps makes Claryo 1.74 lenses almost invisible. The chemically bonded hardcoat and super hydrophobic top coat provide a high level of scratch resistance, which enables Claryo lenses to remain cleaner for longer during normal everyday wear.
Both optimised aspheric surfaces reduce the astigmatism along both axes to deliver distortion free peripheral vision. The improved cosmetic appearance enhances the overall optical performance. Claryo 1.74 DAS SHMC is supplied to order only via a network of privately owned UK prescription laboratories. The power range is -2/-15 with cyls to 4.00 in 65mm,70mm & 75mm diameters.
Essilor: Crizal Sapphire HR No-Glare 
Essilor says its Crizal Sapphire HR No-Glare lenses shield against reflections, scratching, smudging and UV light. The coating is made of nanoscopic layers, which are up to 50 times thinner than a strand of hair and uses High Resistance technology to offer a combination of four specific oxides known for their resistance against dust, scratches, and temperature.
A high-surface density process is said to offer an extra top layer for smudge resistance and a superior ability to repel dirt and water, while 360 multi-angular technology quantifies the overall anti-reflective efficiency (0°-45°) to reduce reflections whatever the light direction from the front and back surfaces of the lens.
Alan Pitcher, commercial director for wholesale lenses at Essilor UK, said: ‘The lenses are easy to clean and offer long-lasting durability, transparency and protection for wearers. The coating outperforms our previous generations by offering lenses up to 70% more scratch-resistance.’
Waterside Laboratories: VFX Honeycomb Mesh 
The VFX lens treatment from Waterside Laboratories is said to be the first-choice option for enhanced visual comfort. Parallel light rays closest to the centre of the lens form the clearest image, but marginal rays at the extremities of the lens, together with lateral light sources and light disturbances, can provide ghost images and blur, which may result in eye fatigue and vision that is not optimised.
Utilising honeycomb mesh technology, Waterside’s VFX lens treatment is said to reduce the effects of light pollution and scattered light rays to provide cleaner and crisper images, resulting in enhanced vision and improved visual comfort.
VFX Honeycomb Mesh is available in a wide range of materials and indices, including clear, tinted and photochromic. It is also offered in a range of lens designs, including Waterside’s Infinity and Elysium progressive families, single vision, and bifocals.
Hoya: Hi-Vision LongLife 
Hoya’s Hi-Vision LongLife coating is said to be a great choice for patients due to its ability to make lenses more scratch resistant, anti-reflective and easier to clean. Hoya says the coating is ideal for anyone who is interested in purchasing lenses and keeping them in a good condition for years to come.
Patients opting for Hi-Vision LongLife coating are said to benefit from additional qualities, including extreme durability, oil repellency for fewer smudges, and water repellency for preventing stains.
Hi-Vision LongLife is also available as Hi-Vision LongLife UV Control. Hi-Vision LongLife UV Control is said to protect patients’ eyes from harmful UV rays, while benefiting from all the qualities of the Hi-Vision LongLife coating. UV Control has an innovative double-sided approach, filtering UV light from the front and neutralising reflected UV from the back of the lens.
Tokai: No Reflection Coating 
Tokai’s No Reflection Coating (NRC) is said to offer patients a natural look with clearly visible eyes without reflections. Tokai notes the importance of eyes when interacting with other people and says its NRC coating allows people to demonstrate a full range of expressions.
NRC is said to achieve low levels of perceived reflections (approximately 0.19%) and is a hydrophobic, ultra scratch-proof and anti-static coating with a fluorine top layer. The coating is said to be ideal for people seeking functionality and fashionability.
According to Tokai, NRC can be further enhanced with an additional digital filter to reduce the negative effects of blue light by approximately 13%.
