Lenses

Plastic or CR-39 - This is the standard thickness lens and is widely used by our lab. Automatically comes with scratchcoat and available in transition, (darken when outside, lighten up when inside).

Glass - These lenses are recommended for patients who easily scratch glasses due to the inherent scratch resistance, but it is heavier and much easier to break or chip. Photogrey is also available (darken when outside, lighten up when inside).

High index plastic lenses- Designed for people who require strong prescriptions, these eyeglass lenses are lighter and thinner than the standard, thick "coke bottle" lenses that may otherwise be needed.

Bifocals- Bifocals are the most common type of multifocal lens. The eyeglass lens is split into two sections; the upper part is for distance vision and the lower part for near vision. They are usually prescribed for people over the age of 40 whose focusing ability has declined due to presbyopia.

Trifocals- Trifocals are simply bifocals with a third section used for people who need help seeing objects that are within an arm's reach.

Progressive lenses- Also called progressive addition lenses (PAL), are corrective lenses used to correct presbyopia and other disorders of accommodation. They are characterised by a gradient of increasing lens power, added to the wearers correction for the other refractive errors. The gradient starts at a minimum, or no addition power, at the top of the lens and reaches a maximum addition power, magnification, at the bottom of the lens.

Anti-reflective coating- further improve the quality and the value of your lenses. An anti-reflective coating reduces disturbing reflections. It makes your lenses more attractive. And you will experience the most precise, crisp and clear natural vision in a brilliance that is not possible with uncoated lenses.
