Biofinity XR CooperVision (3 lenses)
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.

Details of Biofinity XR CooperVision (3 lenses)
Biofinity XR are monthly silicone hydrogel contact lenses manufactured from CooperVision using the unique AQUAFORM ™. This revolutionary technology uses a silicon monomer, which enables more efficient oxygen permeability. The material used in Biofinity XR lenses is non-ionic. On their surface, no areas show evidence of the charge which is why almost no proteins bind to them. A smooth, perfectly moist surface contact lens, Biofinity XR significantly reduces the deposits of lipid residues. The great advantage of Biofinity XR lenses is their aspherical front surface, which improves their optical properties, especially acuity in low light conditions, and enables the correction of astigmatism and presbyopia. Biofinity XR lenses are intended for the correction of high powers – both plus and minus, with a daily wear regimen. Following the recommendation of a doctor however, they may be worn continuously.
Customers who bought these lenses also bought Vantio Multi-Purpose 360 ml with case.
This is a medical device. Read instructions before use.

Hi I need daily lenses
Size..right eye +8.00:8.70:14.10
Size left eyes +8.00:8.70:14.10
Please can you help me to find correct size in daily contact lenses
Kind regards
Miss A Abdie-
ReplyHello,
Thank you for your comment.
HERE - https://www.lentiamo.co.uk/contact-lenses/daily/base-curve-8.70.html - you can find all lenses with a base curve of 8.7. Unfortunately, we do not have any dailies with a diameter of 14.10. The closest one is 14.00.
Anyhow, we recommend contacting your optician before selecting a new brand of lenses.
Kind Regards.

Hello Colin,
Like it says in the product description above: “Following the
recommendation of a doctor however, they may be worn continuously.” The reason
why the doctor's recommendation is important is that some people must take
them off, because of their eyes' conditions.
Of course if you're going to do it occasionally, it shouldn't give you
problems,if you don't suffer from specific pathologies that forbid you to do so.
After all, they are made so that they can be worn continuously.
Best regards,
Fabrizio
