Progressive Lenses

Progressive Lenses
Eyes change throughout our lives, gradually losing the ability to focus on close objects. During our mid-forties, the lenses in our eyes become stiffer, and the muscles that control them change - which eventually causes blurred vision. This is called Presbyopia, and it happens to all of us. You'll probably find yourself holding books, newspapers or product labels further away, or needing more light in order to read clearly.

Progressive spectacle lenses, also called progressive addition lenses (PAL), progressive power lenses, graduated prescription lenses, and varifocal or multifocal lenses, are corrective lenses used in eyeglasses to correct presbyopia and other disorders of accommodation.

They are characterised by a gradient of increasing lens power, added to the wearer's correction for the other refractive errors. The gradient starts at the wearer's distance prescription, at the top of the lens and reaches a maximum addition power, or the full reading addition, at the bottom of the lens. The length of the progressive power gradient on the lens surface depends on the refractive index of the lens, with a final addition power between 0.75 to 3.50 dioptres for most wearers. The addition value prescribed depends on the level of presbyopia of the patient and is closely related to age and to a lesser extent, existing prescription.

Optical Masters Adaptive Warranty:

Don't worry if you've never tried progressive lenses before. Our trained Opticians are at hand to give you expert advice on which lenses to choose and how to get the most from them. As a final reassurance, if at any time within 30 days you are not comfortable with your new progressive lenses, we will exchange them to the same value for more suitable lenses.

Even Progressive lenses cannot offer 100% clear vision - there will be areas of the lenses through which you will see softer focus. The lenses you choose can determine the amount of soft-focus area you experience. A tailor-made lens will enable you to minimize this effect. Varilux Progressive Lenses by Essilor are the most advanced lenses available in the market.
