Glasses Lenses and Coatings

Types of glasses lenses

The kind of vision problem you have determines the shape of the lens. For example, a lens that is concave (curves inwards) it is used to correct short sightedness. A lens that is convex (curves outward) is used to correct long sightedness.

 

We provide a full range of mens, womens & childrens glasses frames & lenses to suit all requirements.

 

Please see the Contact Lenses information for guidance.

 

Call in or ask for more information at your next appointment. 

Single vision lenses

Single vision lenses are available  for:

  • Distance - further than arms length e.g. for driving
  • Computer use - reduces glare from computer screens
  • Reading - needed for close work such as reading, sewing, etc

 

Please discuss your requirements with our optometrist (optician) or one of our dispensing technicians who will fit your glasses.

 

Bifocal lenses

Bifocal lenses are where the majority of the lens is set to the long distance part of your prescription with a lower part of the lens with extra magnification for reading. We measure where the magnification element is situated in the frame in relation to your eye. 

 

This type of lens provides a great solution for many people. However, where there is an intermediate (middle) distance that is unclear it may be better to consider varifocal lenses instead.

 

Discuss your requirements at your next appointment or call in and speak to us.

 

Varifocal lenses

Varifocal lenses, also called progressive addition lenses. 

 

These lenses are often needed as your eyeshight changes due to aging. Between 40 - 50 our lenses change resulting in blurred vision. This condition is common and is called Presbyopia. Varifocal lenses accomodate both short & long sightedness in one pair of glasses (preventing the need to have multiple pairs and the need to change for different uses).

 

Note: these lenses don't suit everyone and it can take perserverence for a number of weeks to get used to them.

Transition lenses & tinting

Lenses can be tinted or change colour in one of two ways (i.e. not both).

 

1. Lens tinting is the cheapest option which is a permanent coloured coating applied to the lens (grey or brown).


2. Transitions lenses, again usually either grey or brown, provide convenient protection from glare & block 100% of harmful UV rays. Indoors they are clear (untinted) and outdoors they react to light levels (go darker) to protect your eyes from glare & the strength of the sun.


We use only top quality Transitions VI Photochromic lenses which means that when your photochromic lenses are indoors they are the clearest they can be. Cheaper brands of this type of 'colour changing lens' can be slow to change or less effective.

Lens thickness & coatings

Lens thickness affects the weight & visual quality of your glasses. Put simply the thinner the lens the better

Options include: 

  • standard lens
  • 1.6   up to 33% thinner & lighter
  • 1.67 up to 36% thinner & lighter
  • 1.74 up to 42% thinner & lighter

 

Scratch Resistant coating

This is applied to the top layer of the lens to form a tougher surface to protect from minor scratching maintaining clearer vision through the lens for longer.

 

Anti Glare coating

This coating protects your eyes from 'glare.'

Glare can come from many sources such as:

  • Night/street lighting & car headlights
  • Computer screens (VDUs)
  • The sun


If you choose to have both coatings on your glass lenses they provide multiple benefits including a treatment called hydrophobic (which automatically clears the lens if they become 'steamed up').
