What Is The Difference Between Biofinity And Biofinity Toric?

The difference between Biofinity and Biofinity Toric is the prescription each lens is made to correct. Biofinity is a monthly spherical lens for nearsightedness or farsightedness, while Biofinity Toric is a monthly toric lens for astigmatism. Biofinity Toric adds cylinder and axis values, so the lens can correct uneven focusing that standard spherical lenses do not address. Both lenses are made by CooperVision with comfilcon A silicone hydrogel and Aquaform Technology, but they have different fit measurements, prescription fields, and lens designs. Wearers should order the exact product named by their eye doctor, since switching between the two requires a new contact lens prescription.

Comparing Biofinity And Biofinity Toric Contact Lenses

Biofinity and Biofinity Toric sit in the same monthly lens family, but they solve different prescription needs. A side-by-side review helps wearers understand why the product name, sphere power, astigmatism values, base curve, and diameter should be matched before ordering boxes.

• Biofinity corrects nearsightedness or farsightedness with spherical power for wearers without astigmatism correction in their contact lens prescription.
• Biofinity Toric corrects astigmatism along with nearsightedness or farsightedness, so its prescription includes extra alignment values.
• Biofinity prescriptions usually list sphere power, base curve, and diameter without cylinder or axis fields.
• Biofinity Toric prescriptions add cylinder and axis values, which must match the eye doctor's written prescription.
• Biofinity lists an 8.6 base curve and 14.0 diameter in current specifications for the standard lens.
• Biofinity Toric lists an 8.7 base curve and 14.5 diameter in current specifications for the toric lens.
• Both lenses use comfilcon A with 48% water content and Aquaform Technology for monthly wear.
• Both are monthly replacement lenses when worn as prescribed and cleaned with an approved care system.

Accurate selection starts with the exact lens name and prescription fields for each eye. A shared product family does not make standard Biofinity and Biofinity Toric interchangeable during checkout or refills.

Astigmatism Correction And Lens Stability Differences

Astigmatism changes how light focuses, so a toric lens needs more than sphere power. Biofinity Toric uses cylinder and axis values to correct that uneven focus, while standard Biofinity does not include those fields. Biofinity Toric also uses a lens design made to settle in the correct orientation during wear, since rotation can affect clarity. That is why its base curve and diameter differ from standard Biofinity. If your prescription includes CYL and axis, standard Biofinity will not carry the complete correction your eye doctor prescribed.
