When selecting contact lenses, understanding the technical differences between high-street brands like Specsavers' easyvision and their manufacturer equivalents can significantly impact both your eye health and your wallet.

Umere vs Linarial

Technical Performance

Both Umere and Linarial are premium daily disposable silicone hydrogel lenses manufactured by CooperVision. While they share a high-performance material, they differ in their specific hydration technologies and breathability.

Breathability

Linarial (the equivalent of MyDay) offers an oxygen permeability (Dk/t) of 100, whereas Umere (the equivalent of Clariti 1 Day) typically operates at a slightly different oxygen profile.

Water Content

Both lenses prioritize hydration, with Linarial maintaining a 54% water content to ensure a smooth, "forgettable" wearing experience.

Technology

Linarial uses "Smart Silicone" chemistry, which uses less silicone to create more space for moisture channels. Umere utilizes the "Aquagen" process for continuous wettability.

The Meaning of "Linarial" and Equivalents

In the optical industry, "Linarial" is a private-label name used by Specsavers. Its "clinical equivalent" is the CooperVision MyDay. Identifying these equivalents allows users to find the same lens under different branding, often at lower prices online.

Serima Sphere and Its Equivalents

The easyvision Serima Sphere is another daily disposable option, specifically designed for nearsightedness or farsightedness.

Material

It is a silicone hydrogel lens with a 47% water content.

Equivalent

A common clinical equivalent for the Serima range is often found within the CooperVision MyDay or Proclear families, depending on the specific sub-type prescribed.

Enhancing Comfort

Comfi Colours & Hycosan

For those looking to combine vision correction with aesthetics or extra comfort.

Comfi Colours & Enhance

Comfi Colours are popular daily disposable coloured lenses. The "Enhance" range focuses on intensifying the eye's natural shade while maintaining high water content for comfort.

Hycosan Extra

For users experiencing dry eyes with any lens brand, Hycosan Extra is a preservative-free eye drop containing 0.2% Sodium Hyaluronate. It is widely available, including at Tesco Pharmacy, often used to provide long-lasting relief for "gritty" eyes.

While all three options are made from breathable silicone hydrogel, you can choose Umere (Clariti 1 Day) for its 56% water content and UV protection value, Linarial (MyDay) for a high oxygen transmissibility of 100 Dk/t and exceptional smoothness, or Serima Sphere for a focus on daily freshness with 47% water content.
