Advances in lenses

Have you seen the lens options that are available for your frames?   There are so many exciting advances in the designs and materials for lenses.  A number of different elements contribute to creating your own modern, distinctive lenses.  The right combination will enhance lens performance giving you increased comfort and style.

Andrew Knights Optometrists can fit your prescription to your lifestyle and comfort needs, no matter if you need glasses for long distance or short distances, they will tailor them to maximize your vision requirements.

Lens Designs

Computer aided design has created lenses not possible ten years ago.

  • Single vision lenses – The most commonly prescribed lens allows you to see clearly in either distance or at near.
  • Multifocal lenses – allows the wearer to focus at more than one distance.
  • Bifocal lenses – two distinct segments, top segment – used for distance and lower used for close range tasks.
  • Trifocal lenses – three distinct segments, allows wearer to focus on mid range as well as near and distance
  • Progressive lenses – gradual change between distance and near, aesthetically more attractive as it provides more natural vision that bifocals and trifocals.

Lens Materials

High prescription lens wearers might want to consider a lens material that makes your lenses thinner and therefore more attractive.  This enables you to have the frames you desire and make you feel more confident when wearing your glasses.  The lens material specifically used is plastic (resin), which is lighter and thinner than the usual glass lenses and avoids the ‘coke bottle’ appearance.

Lenses in the past have been heavy and uncomfortable on your face, disrupting your day to day activities.  Ask your optometrist about the lightweight and highly impact resistant lens, which provides optimal wearing comfort.  This lens material is called Hoya Phoenix. They are ideal for children, safety and sporting applications.

Lens tints and coatings

Coatings will help extend the life of a pair of glasses although not prevent all scratches.  Below are coatings you can consider to maximize your vision requirements and the life of your glasses.

  • Anti-reflective coating – will minimize distracting reflections, improve your clarity of vision, particularly at night and achieve a more natural, attractive appearance.
  • Scratch resistant coating – For improved durability opt for a scratch resistant coating on both sides of your lenses
  • UV coating –Some lenses already provide guard against 100% of the sun’s UVA and UVB rays, however a UV coating can be applied if this is not provided
  • Glare protection – Polarised lenses or prescription sunglasses are recommended for people who are outdoors frequently.
  • Tinting – Transitions lenses are lenses, which change tint in response to light and IV to provide comfortable vision in varying lighting conditions.

The cost of a pair of spectacle lenses can vary, depending on the exact type of lenses.  The cost depends on many factors, such as the lens design, lens material, coatings, tints and the prescription.

Discuss these considerations with your optometrist, who will help you find the best lens solution for your visual needs.
