which lens

is right for me?!



Single Vision..

Ask the lens experts- which prescription lens is right for you?

You see your frames every day, so of course you want something that's comfortable and looks good. But your lenses are what you're actually looking through- for many people this is all day, every day. So it makes sense to have a real conversation about lenses when getting new glasses.​​

Our resident lens experts, Michelle and Gloria, have made a little lens cheat sheet to help explain the different lenses available and even included a brief pros and cons for each!

Key: Different lenses are designed for different things (reading, intermediate or distance). These arrows are highlighted to represent what a particular lens type is used for.

Single Vision

Use: Near or distance

These are the most basic type of lenses. They give clear vision at one distance only- near, intermediate or distance.  

Perks: Perfect if you only need correction for one thing, such as only reading or only distance. No side distortion like multifocals. Generally budget friendly.

Cons: Need to take glasses on and off, can only correct one distance.


Uses: Near and distance

These lenses have two defined segments.  Most commonly, the top half of the lens is used for distance, with the bottom half used for reading.   The reading area is usually shaped like a half-moon or circle.

Bifocals are an older design, which have become less popular over time in favour of multifocal and extended focus lenses, however we still prescribe a number of bifocal lenses. 

Perks: No side distortion as with multifocals. Larger viewing area as lens is only split into two areas, unlike multifocals. Older patients who are used to bifocals may prefer them to multifocals.

Cons: Outdated design. Harsh jump between near and distance vision. Obvious line on lenses is less aesthetically pleasing.

Extended Focus

Use: Desk (Near and intermediate)

For those desk warriors out there! Just like a super-powered single vision lens, extended focus or "Desk" lenses give clear close-up vision, but also provide you with intermediate vision too. 

This range should essentially give you great vision across your entire desk area, from the paperwork you're reading to your computer monitor- hence their nickname as a "desk" lens.

Perks: Large viewing area as lens is only split into two areas, unlike multifocals. Great option for those who need more than a single vision lens, but aren't quite ready for full-time glasses.

Cons: Like multifocals, designs vary- some desk lenses are unsuitable for dual monitors, so you need to specify to your optometrist how your desk is set up so we can prescribe the best design for your needs. Can't walk around in them.


Uses: Near and/or Intermediate

Anti-fatigue lenses ease eye strain caused by digital devices.

They have an added ‘boost’ in the lower part of the lenses to reduce eye strain that can occur with extended reading or computer use.


Anti-fatigue lenses also incorporate a special coating that filters out blue light, which may further assist with reducing eye strain caused by extended use of electronic devices.

Blue light is emitted from digital devices and fluorescent lights, is shown to increase eye strain and even interfere with your melatonin production- affecting your circadian rhythm and in turn your sleep. You can read more about Blue Light here


Perks: Eases eye strain caused by digital devices. Can be added to any lens. Can be prescribed to anyone- even if you don't have a prescription but suffer from sore eyes. 

Cons: Almost none. Can very slightly alter the look of colour (may be a consideration for those doing very colour-sensitive work), but this is imperceptible to most. Not recommended for very high prescriptions.

For those desk warriors out there! Just like a super-powered single vision lens, extended focus or "Desk" lenses give clear close-up vision, but also provide you with intermediate vision too. 


Uses: Near, intermediate and distance

Also known as progressive lenses, these lenses provide clear vision at all distances (near, intermediate and far away).

Getting multifocals is a more complicated process. Precise measurements need to be taken for your individual eyes and face, and a frame must be selected that sits well and has enough depth to accommodate the lens- but don't let this deter you!

Our experienced optical dispensers- also known as our "lens experts" are always on hand to help you choose the perfect lenses for your needs.

Perks: More gradual and natural transition between focal areas than bifocals. Convenient- no switching between glasses. Cheaper than two separate pairs of glasses. Thinner and lighter than single vision & bifocals- particularly for higher prescriptions. Aesthetically more pleasing. Lots of designs suited to various lifestyles and uses.

Cons: Narrower field of view and side distortion- more noticeable in low quality/cheap lens designs and higher scripts. May take some time to adapt.
