LENSES TO FIT EVERY BUDGET

Whether you looking for state of the art lens designs or simply for the best value we would be glad to help you choose from our comprehensive catalogue of available eyewear lenses.

When choosing lenses the main factors to consider are the lens design, the material that the lens is made, the coatings applied to the lens surface and any tints required for cosmetic enhancement or glare protection.

With the many lens choices available today we are happy to discuss and explain all of the options available for your prescription and lifestyle.

COMPARE OUR LENSES THICKNESS

Single Vision Lenses correct for only one distance and are now available with digital enhancements to reduce lens distortion for sharper vision over a wider field of view.

Aspheric lenses reduce peripheral distortion while also reducing the lens thickness especially in plus lenses where the bulge of the lens is reduced dramatically. Most high index lenses include an aspheric design to reduce the lens thickness by an additional 10%.

Designed for the digital age Anti-Fatigue lenses reduce the eyestrain cased by digital devices which are generally held closer to the eyes than regular reading material. Reading small print at closer distances make the eyes work harder to focus causing eyestrain over time.

Digital Wrapped Lenses are lenses that wrap-around your eyes for safety or to effectively block glare from the sun at all angles. These lenses are used mainly in prescription sunglasses for motorcyclists, boaters and fishermen to protect their eyes from wind and the harsh glare of the sun off the water. Digital technology will give you a wider field of view free from distortion for better peripheral vision.

Bifocal Lenses have two sections where one section is for looking in the distance with another section to see at near or for reading. There are various shapes and designs of near vision segments with some blended onto the lens to make them almost invisible.

Similar to Bifocal Lenses except there is an additional segment that is generally used to see at an intermediate distance with a much wider field of view than progressive lenses.

For over 40 years we have been studying the evolution of progressive lens design from all of the major lens suppliers. Progressive or “No Line Bifocals” are the modern way of allowing people to focus at any distance with one pair of glasses. Digital technology has made progressive lenses easy to use while offering lifestyle enhancements that increase viewing areas according to your needs. Our understanding of how the various Progressive lens designs relate to different prescriptions and lifestyle requirements will help us advise you to make the best lens choices for your needs.

Computer Lenses are designed to be used at computer workstations or for any task that requires a wide clear field of view in an indoor environment. Computer or office lenses allow you to maintain a normal head position to easily focus on your work so that you will be more efficient with fewer errors.

Vocational lenses are designed so that you can read normally while also being able to see at an intermediate distance above your head. These lenses have near or intermediate segments located on both the upper and lower portion of the lenses to give clear vision at any required distance.

The Index of Refraction is a number that relates to the ability of the material to bend light.  Lenses with a higher Index of Refraction will be thinner than lenses with a lower Index of Refraction.

The Abbe Value is used to describe the amount of chromatic aberration in a lens material. Chromatic aberration is an optical distortion visible as coloured haloes around object especially lights at night. Most people will not notice a difference when looking though the different lenses materials.

Index: 1.498
Abbe Value: 58

The original plastic lens material developed in the 1940’s is CR39 which also remains the least expensive and is commonly used in all lens designs.

Index: 1.523
Abbe Value: 58

The original Lens material used in eyewear and optical devices since the middle ages offers excellent optical properties and durability from scratching. Glass is the heaviest lens material and is more susceptible to breakage so is not allowed to be used for industrial eye protection. Not commonly used today but it is still available in limited lens designs.

Index: 1.561
Abbe Value: 36

This mid-Index material offer excellent value while reducing the lens thickness of a prescription lens by about 15%.

Index: 1.532
Abbe Value: 45

Trivex is the most modern of lens materials while also being the lightest and most breakage and chip resistant. This material is not available from all suppliers or in all lens designs.

Index: 1.59
Abbe Value: 30

Polycarbonate blocks 100% of UV and is the least expensive impact resistant material commonly used in safety eyewear and children’s glasses for eye protection. Since this lightweight material is more prone to scratching a good quality scratch resistant coating is recommended.

Index: 1.6
Abbe Value: 36

This impact resistant material is recommended for frames with mountings that are drilled into the frame or to simply reduce lens thickness by up to 25%.

Index: 1.6
Abbe Value: 44

Very rarely used in this day and age but still available from some European based suppliers for thinner glasses lenses.

Index: 1.67
Abbe Value: 32

This impact resistant material is ideal to reduce the thickness of stronger prescriptions and is available from all suppliers in varying prices according to the quality of the coatings.

Index: 1.74
Abbe Value: 33

This is the thinnest plastic lens material available which is recommended for stronger prescriptions requiring the thinnest possible plastic lenses.

Index: 1.7 to 1.9
Abbe Value: 39 – 30

The thinnest possible lenses with optical propertied that vary with the quality of the glass used. These lenses are used for very strong prescriptions and only available from specialized suppliers.

All plastic lenses available at Whalley Optical have a scratch resistant coating applied to both sides of the lens to help protect the lenses from daily wear and tear.

Anti-reflective coating reduce lens surface reflections to let you see the world more clearly while allowing other people see your eyes better. Especially effective at improving night vision while driving by eliminating ghost reflections caused by streetlights and car headlights.

Applied to anti-reflective coatings this added feature reduces the electrostatic charge caused by rubbing your lenses with a cleaning cloth so that the dust in the air is no longer attracted to your lenses keeping them cleaner longer.

When applied to anti-reflective coatings this added feature smooths the lens surface to make it much slipperier so that dirt or water droplets do not stick to the lenses. Hydrophobic coatings also reduce lens fogging when moving from cold air to a warm area.

Available as an added feature or included in many anti-reflective coatings a UV filter will protect your eyes against the harmful effects of Ultra Violet Radiation. Whey you are outdoors without proper eye protection the crystalline lens in your eyes will absorb the suns UV radiation gradually clouding your vision over time by causing cataracts.

Blue Light Radiation is emitted by the sun, digital screens (TV’s, computers, smart phones, and tablets) along with fluorescent and LED lighting. Studies are showing that long term exposure to Blue Light Radiation may cause retinal damage and contribute to age-related macular degeneration. Protecting your eyes from Blue Light will also reduce digital eyestrain and normalize your circadian rhythms which are triggered by Blue Light Radiation.

Photochromic lenses are activated by UV radiation from the sun which causes them to darken when exposed to sunlight. Wearing photochromic lenses automatically protects your eyes from UV radiation and glare while reducing eye fatigue caused by squinting into the sun. Available in an assortment of tint colours and darkness’s these lenses offer the ultimate in easy to use complete eye protection.

.

Polaroid lenses are laminated lenses containing a Polaroid film which is the most effective way of reducing glare from shiny surfaces such as chrome on cars and the surface of water.  These lenses are prized by fly fishermen because the Polaroid effect reduces the surface reflections on water allowing the fish underneath to be more easily seen.

Lenses can be tinted to any colour of the rainbow in either a solid colour or a graduated tint. A solid tint will reduce glare from bright light while a graduated tint blocks glare while adding a touch of style. The tint density can vary from just a light tint to take the edge off glare or to add some colour around the eyes to darker tints for eye protection.

When driving in city traffic the distracting glare of oncoming headlights can be reduced with a high contrast tint applied under an anti-reflective coating. Care must be taken when using tinted lens for night driving because any tint in the lenses will reduce the amount of light getting to the eyes.

YOUR EYES. OUR COMMITMENT.

“”Hi – just got home from work and what a great way to end the work week – my new glasses were waiting.

I’ve got them on as I type this and they are PERFECT!! They line up perfectly – the tint is amazing – and this has been a bad migraine day for me – which means severe sensitivity to light… these are so soothing to my eyes even around the house, especially with the bright sunlight coming through the windows, I didn’t have to close the blinds. Can’t wait until Monday to wear at work…

Again, thank you – thank you.”

Sincerely – Arlene
