How to select parameters?
Power (PWR/SPH)
Power or sphere refers to the refractive power of the contact lens. Look for a plus (+) or minus (-) sign. Note that an equals sign (=) may be used in place of a minus sign.
- dioptres are for problems with near vision (far-sightedness)
+ dioptres are for problems with distance vision (near-sightedness)
Curvature (BC)
The base curve describes the curvature of the contact lens surface, i.e. how well the lens fits the shape of your eye.
Diameter (DIA)
The diameter is the width of the contact lens (measured in millimeters). It is not recommended to select a new diameter size without first consulting your optician. Diameter impacts the fit, comfort and functionality of your lenses.
Cylinder (CYL)
The cylinder measurement is used for the correction of astigmatism. It is a negative value that corrects curvature of the cornea.
Cylinder Axis (AX)
The cylinder axis measurement is used for the correction of astigmatism. The value ranges from 0° - 180° and determines the exact position of corneal curvature.
Addition (ADD)
Addition is the difference between the dioptric value for distance vision and the dioptric value for near vision. It indicates the magnifying power in multifocal lenses.

Biomedics 1 Day Extra are available in packs of 30, 90, or 180 lenses for your convenience. If you have different prescription values for each eye, the 30-pack will last you a month, the 90-pack for three months, and the 180-pack for up to six months.
Choosing a larger box size gives you better value for your money. The 30-pack is perfect for those who prefer to wear contacts occasionally. The bigger packs, although pricier, are an investment that can save you money in the long term, especially if you wear contacts daily.

Hi
Can you confirm these are the same as the CooperVision options extra 1 day lenses?
Thanks-
ReplyHi Steven, I actually searched for the “CooperVision options extra
1 day” lenses on the CooperVision website, but I couldn't find them. I can
assume they might be, but when in doubt about something as delicate as contact
lenses, I would try to find the correct name of the product. I'm sorry if
I couldn't be more helpful.
