Although it is the frames we look at when people have spectacles, it is the lenses that are all important for correcting vision. Lenses will turn the blurry into clear by bending the light so that it focuses clearly on the back of the eye, or retina. Your choice of lens will depend largely on what you want to do while wearing your new glasses.

Lens options

Hi index, aspheric Thinner, lighter lenses. Cosmetically nicer and more comfortable to wear. Used especially with high refractive errors.
Polycarbonate Light, strong material. Ten times more impact resistant than normal lenses. Recommended for safety glasses for sport or work.
Multicoat  Anti-reflective coating reduces reflections off the front surface of the lens. People see your eyes rather than your glasses. Also helps with glare from lights and computer.
Scratch resistant coating  Helps protect from scratching but lenses can still scratch. Keep them in their case for the best protection
Transitions React with UV light to change from clear to tinted when you go outside. Can save having one pair of clear and one pair of tinted glasses
UV coating Plastic lenses will shield out most UV but having a UV coat will give 100 per cent protection. UV light contributes to many ageing conditions of the eye.
Glass lenses Most lenses now prescribed are now made from plastic which is lighter and more impact resistant than glass.

Single Vision or Multifocal

Single vision lenses are the most straightforward lenses and can be for distance, near or sometimes intermediate distances. People can wear single vision lenses for special tasks, like driving or reading or playing the piano. Often these glasses are taken off when these activities are over. Because single vision lenses are simpler they often cost less than multifocal lenses.

Multifocal lenses are used when more than one pair of glasses is required to correct vision or to save someone from constantly taking their glasses on and off. Multifocals have a gradual change in prescription from the top of the lens, which is clear for distance, down to the lower part of the lens, which is clear for near.

Multifocal lenses 

  • Are great for use in the office environment
  • Different designs are available to fit into different sized frames
  • Should not be used by people who are unsteady on their feet
  • Can also be used in children to help binocular vision problems

Multifocals or bifocals?

Most people are prescribed multifocals now, but bifocals are still available. Bifocals have two prescriptions – one distance and one near, with a line in between.  Advantages of multifocals over bifocals include

  • They look nicer cosmetically (no line)
  • They also correct the intermediate distance (good for computer)
  • There is no ‘jump’ between the prescriptions, just a gradual change

Looking after glasses

Glasses can last at least a couple of years if you follow these tips:

  • Use the cleaning cloth provided with the glasses (not your shirt!)
  • Put the glasses away in their case when not in use
  • Take the glasses off with both hands
  • Do not try to adjust the glasses yourself – it is better done by a professional

Most frames purchased from us have a 2-year warranty for any manufacturer’s faults. If lenses are scratched, unfortunately they are not able to be repaired. We are always happy to do any adjustments to your frames that are required – just bring them in.
