LENSES




At Frederick Swain Optometrists, your Optometrist and our dispenser will work together with you to select the lens that is going to suit your individual needs, your lifestyle and your budget.

Types of Lenses

Single Vision Lenses

If you are under age 40 and need prescription glasses, then single vision lenses may be sufficient enough for your visual correction. Single vision lenses have the same focal power throughout the lens to provide a single focus whether it be for distance or reading.

Bifocal Lenses

An older style of lens to view 2 focal points of vision, distance and reading within the one lens with an obvious segmentation.  This lens is also suitable for wearers who do not adapt well to a progressive lens style.

Progressive Lenses (Multifocal Lenses)

Progressive lenses provide a gradual change in power within the lens to view 3 focus points of distance, intermediate and close up without obvious segmentation.  Our Optometrist will discuss the best style of lens to suit your needs.



Lens Coatings

There are various benefits of having a coating on your lenses.

  • Hard Coat coatings will prolong the life of your lenses and assist with scratch resistance.
  • Anti-reflective coatings help transparency in the lens and cut out glare from various lighting sources.
  • UV coatings protect your eyes from absorbing harmful UV rays. Long term exposure to these UV rays can cause irreversible damage to the eye.  The UV coating blocks 95% of the UV rays transmitted by the sun.

Transitions Lenses

Transitions lenses are clear indoors and at night. Once outdoors, the lenses darken spontaneously to varying light conditions so you can enjoy:

  • Comfortable vision through reduced eye fatigue and less squinting in the sun
  • The convenience of one pair of everyday glasses for indoor and outdoor use
  • Everyday protection from harmful UV rays through 100% UVA and UVB absorption.

Transitions lenses are recommended to wearers of any age. They are available in brown, gray and green transitional colours which suit all prescriptions  (single vision, bifocal and progressive).


Polarised Lenses

Polarised lenses give you better protection and comfort than tinted lenses.
Ordinary tints can reduce brightness and provide UV protection (if they are properly treated), but only Polarised lenses can reduce glare even further eg  the suns reflection off snow, water and other vehicles whilst driving.  They provide better clarity of vision and have the ability to enhance colours to their true richness. Polarised lenses completely block UV rays providing 100% UVA/UVB protection – reducing potential vision damage.
