Choosing the Right Lens for You

There are many lens designs, materials, coatings and treatments available. Your choice will depend on your prescription, your lifestyle and your budget. Your Optomeyes optometrist will guide you through these steps to find out the best combination for you. Our preferred choice for lenses is world-renowned quality lens designer and manufacturer Essilor, who stock Nikon and Varilux products.

STEP 1: LENS DESIGN

Single Vision Lenses are used to correct common visual defects such as myopia, hyperopia or astigmatism.

Progressive Lenses offer the best solution to presbyopia. Since Essilor developed Varilux®, the world's first progressive lens, people over 40 have been able to enjoy natural vision from near to far. Varilux® lenses offer a wide, uninterrupted field of vision plus a youthful appearance.

Bifocals offer far and near correction, but this older style of lens has an obvious line that affects vision, is not as cosmetically attractive and is hazardous for some older wearers.

Reading Glasses can also be used to correct presbyopia. They correct near vision (less than 1m), but objects at all other distances will be blurred. This is often inconvenient and if you require glasses for driving, two pairs of spectacles may be needed. There are now enhanced reading spectacles which allow a better range of vision for close tasks allowing you to read and yet see you computer.

STEP 2: LENS MATERIALS

Talk to Optomeyes about your hobbies, profession and fashion tastes, so together you can determine the lens material that will give you maximum comfort and the best vision possible.

Plastic Lenses are the most common lenses throughout the developed world. They are impact resistant and light weight so they have all but replaced glass lenses.

High Index Lenses are lighter and thinner than standard plastic lenses their advantages increase especially for strong prescriptions. There is a wide variety of plastic high index lenses.

Polycarbonate Lenses are incredibly light, up to 27% lighter than standard lenses. They are also very strong up to10x more impact resistant than regular plastic, so are the lens material of choice for safety spectacles. Polycarbonate also has in-built UV protection. Essilor Airwear polycarbonate lenses come in clear and polarised versions so they are great for regular glasses and sunglasses. They are perfect for children, sports people and anyone who follows a vigorous lifestyle.

STEP 3: LENS TREATMENTS

A number of treatments which are usually incorporated into your lenses to enhance their performance and appearance.

Scratch Resistant Treatments increases the durability of plastic lenses. Essilor's hardcoat -- TD2 -- offers a tough, durable, two-sided, protection for both the front and back of your lenses, which is applied after the lens prescription is ground onto the lens.

Anti-Reflection (AR) Treatments (Multicoatings / Alize A2) give you the clearest vision possible by eliminating unwanted reflections. They enhance contrast and improve night driving. With no reflections the lenses are virtually invisible and people see your eyes more clearly. Anti-Static, the latest addition to anti-reflection treatments, is an ingenious layer taking charge away from the lens surface and actually repelling dust, making lenses even easier to keep clean. Crizal A2® is Essilor's 'All-in-One' coating which offers the best combination treatment of easy-clean, anti-static, scratch resistance, UV protection and anti-reflection. This treatment makes lens look better and your see better.

Transitions Lenses darken in sunlight, are clear indoors and protect against UV rays. They are available in a wide variety of materials (some materials are thinner and more light weight) and come in almost all lens designs.

Polarising Lenses protect against the sun's reflected glare particularly from surfaces such as water, snow, sand, car bonnets etc. In a range of designs and materials, polarising lenses make for the most comfortable prescription sunglasses.

Drivewear Lenses are a combination of polarizing and Transition technologies. They protect against the sun's reflected glare as well as lighten and darken to sunlight. In a range of lens designs and materials.

UV treatment. This special treatment protects your eyes by blocking the sun's UV light that can damage your eyes.

Tints in a wide range of colours and densities can be applied to plastic lenses. However, tinting alone will not protect your eyes from UV rays. Before choosing standard sunglasses, ensure that they also include 100% UV protection.
