SINGLE VISION LENSES

Single vision lenses are the most common type of lenses prescribed and are for those who only require one prescription, such as for distance or near vision, or for those who would rather wear separate pairs of glasses for each prescription as opposed to a varifocal or bifocal. At Harpenden Eye Centre, we offer a few different types of single vision lenses:


STANDARD SINGLE VISION LENSES


These lenses contain one prescription over the entire surface of the lens. These lenses offer a good standard of optical quality  and are suitable for general purpose. 


ASPHERIC SINGLE VISION LENSES


Aspheric single vision lenses also contain one prescription over the entire surface of the lens, though provide a wider visual field than standard lenses. The optical clarity is clearer in these lenses. The most significant advantage of aspheric lenses is that they reduce eye magnification,  which is especially beneficial to long-sighted patients who worry about the cosmetic appearance of their glasses. 


INDIVIDUALISED SINGLE VISION LENSES


These lenses have all of the above properties of aspheric lenses, though are made using specialised computer technology to tailor the lens to the patient's personal wearing conditions. Individualised lenses alter the patient's prescription for all directions of gaze, rather than just the prescription found in the test room when the patient was looking straight ahead at the 'Letter Chart'.  This means the wearer will benefit from unsurpassed visual sharpness over the entirety of the lens surface,  giving a more accurate correction than standard single vision lenses could ever provide.  This lens type has often been referred to by our patients as 'The HD Lens' (High Definition).
