Intro – Types of progressive lensesProgressive lens are “multifocal” lenses that offer a smooth progression of several lens powers for very optimised vision across the region, usually near distance being at the bottom and far distance viewing at the top part of the lens. Observing how progressive lens are made let you understand the special characteristics associated with every design. Before that, let us introduce the structure or design of a progressive lens. There are 4 major parts on the lens.
- Green : Distance Vision
- Yellow : Intermediate Vision
- Red : Near Vision
- Blue : Blurred area
- Smoother transition from distant power to reading power thus reducing waviness
- Wider corridor to allow more stable vision
Traditional progressive glassesOne of the old forms in the types of progressive lenses. This form of lenses makes use of a semi-finished lens which will is molded with virtually no cylinder (spherical power) at the front. Instead, the particular spherical power will be added at the backside of the lens. However, this sort of progressive lens is quickly becoming obsolete, because this isn’t accurate since other better choices are now available. The specific corridors are narrower (the part of the lenses associated with power that corrects your vision).
Digital progressive lensesThis types of progressive lenses designs give the most optimum view when the particular wearer’s optical needs are taken into the design consideration. The particular difference between digital progressive and traditional progressive lens is digital’s capability to do custom areas within a lens, to tailor to an individual’s needs. Digital progressive lenses make sure that the most precise prescription can be tailored according to a person’s face, plus how do you wear your glasses as well as the position of your eye.
DIGITAL FREE-FORM LENSESThe latest types of progressive lenses are digital free-form type. If available at the glasses store you visit, they would get recommended by opticians because they come along with huge benefits.
