Dioptres (D/dpt./PWR)
look for the figure on your prescription written as the 'dioptre sphere'. Beware of a + or - (minus = is replaced).
+ dioptres with problems with near vision (far-sightedness).
- dioptres with distant vision problems (near-sightedness).
Curvature (BC)
a parameter that provides the highest comfort while wearing lenses, i.e. how well the lens attach to your eye
Diameter (DIA)
This is the diameter (or size) of lens. If you have some lenses with a specific diameter that suit you then stay with them. It is not such an important parameter, but a different diameter size would be a gamble.
Cylinder (CYL)
an indication of negative values, which make any correction for the curvature of the cornea
Cylinder Axis (AX)
a value in the range 0° - 180°
Addition (ADD)
Indicates the difference between both your myopia and your hyperopia in dioptres
A clear choice for an optimal vision

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 Solunate Multi-Purpose 400 ml with case.

ReplyHello 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
