Biotrue ONEday from Bausch and Lomb are
daily, hydrogel contact lenses. These innovative contacts' design
is inspired by the biology of the human eye to closely match the internal
properties and behaviour of each eye. Thanks to this, they provide all-day
comfort and hydration while allowing a sufficient oxygen supply to reach the cornea. This package contains 90 lenses.
I'm confused as to what BC & DIA are. My prescription doesnt refer to these abbreviations.
It shows Sph, Cyl and Axis with similar readings for both eyes although the strength of my contact lens varies for each eye. Additionally, the axis numbers are vastly different for each eye.
Currently, my contacts lens are +4.75 and +2.50
I would welcome any advice please

Hi, Maz, BC and DIA mean base curve and diameter, respectively. These values
are not so much indicative of your prescription and are more for which brand
will be the best fit for your eye. Base curve is the radius of the back of your
lens (i.e. how far your lens protrudes), and diameter is the area of your cornea
your lens encompasses and is contingent upon the size of your eye. If you do not
know, you should be fitted for lenses by your optometrist.

Do you have these lenses and do they work as multi focal?
