Leave your big PD, unless your monitor is extremely close (less than 18”), in which case, you may wish to narrow the PD by one or two millimeters. Note: Most companies do not do bifocal lenses with an Add of less than +1.00. The balance of the Add will stay in that data entry field. If you would like to order bifocal lenses for computer and reading use, just simply split the Add number in half and combine half of the Add with the Sph. And use the small PD 62mm(if your doctor did not provide the reading PD, please narrow the PD by 2-3mm from the distance PD). In the case of the Positive Add and a negative Sph, net the difference, and the new number becomes the Sph. Here is the standard format:įor reading only glasses, you just need to combine the Add and Sph prescription. If you would like to buy Single vision glasses for computer use ,you will have to split the Add number in half, and combine that split number with the Sph, Ignore the remaining Add and use the bigger PD 64mm. If you would like to order single vision glasses for far distance only, just simply leave off the ADD strength and use the bigger PD (distance PD) 64mm.

Trevor Woodhams, M.D.With the growing popularity of prescription glasses, the demand for cheap glasses and discount glasses online is on an upward slope. Optometry grew out of the opticianry business where oculists (an old word for eye doctor) actually had to grind a lens blank flatter in a particular direction to treat the astigmatism, hence the minus (subtracted) number along that direction. Ophthalmologists (MDs) are typically taught in plus cylinder and Optometrists in minus. The reason for the two different conventions is historical. This doesn't mean the cylinder is changing -just that the steepest meridian is 1.0 diopter more than the flattest: the minus or the plus notation indicates whether you are measuring from steepest meridian to the flattest or from flattest to the steepest! Alternatively, it could be written: -4.00 +1.00 x 180.˚ The amount of the cylinder is also the same, but lies along the opposite orientation (90˚ away). For example, a right (or left) eye's line on the Rx form might read: -3.00 -1.00 x 90˚ (minus cylinder convention). In effect, it depends on whether you measure from the "top to the bottom" or the other way round. They are functionally the same (at least at the level of accuracy required in spectacle lenses). There are two conventions used among eye doctors on how to notate a typical glasses prescription: minus cylinder or plus cylinder.
