Monthly disposable silicone hydrogel lenses

From the time we open our eyes in the morning until we close them again at night, our days and our lives are defined by what we see. That is why we chose 'Miru' a Japanese verb meaning "to see" as the global brand name for our visionary new range of contact lens products.

The first product from this new “Miru” range, the soft contact lens 1month Miru features the dual technologies of MeniSilk & Nanogloss and provides wearing comfort and optimal tolerance even late at night, throughout the month.

The presence of the moisture-binding molecule MeniSilk during the polymerization phase and the highly controlled smooth surface technology Nanogloss at the nanometer level improve contact lens wettability, increase lipid resistance and minimize bacterial adhesion, providing better wearing comfort.

The soft contact lens 1 month Miru is manufactured using the advanced silicone hydrogel material 'asmofilcon A', which delivers an outstanding level of oxygen transmission (Dk/t: 161). With a balanced modulus and a lavender handling tint, 1month Miru is an easy to wear monthly replacement lens. 

Key Characteristics

1month Miru is designed with balanced properties that support our aim to provide the best possible monthly contactlens for both eye care practitioners and their patients. It also offers the best possible wearing experience for patients whilst providing an exceptional level of safety.

Low Bacterial Adhesion

Optimal Corneal Oxygenation

Minimal Lipid Deposition

Minimal Sensitivity

Low Bacterial Adhesion


As part of its ongoing aim to provide a safer and cleaner contact lens wearing experience. Menicon has developed a unique and highly sophisticated surface technology as part of its ongoing aim to provide a safer and cleaner contact lens wearing experience. 1month Miru's, asmofilcon A material demonstrated the lowest level of bacterial adhesion to the lens surface when compared with five commercially available silicone hydrogel contact lenses.

Optimal Corneal Oxygenation


The 1month Miru silicone hydrogel contact lens has one of the highest levels of oxygen transmissibility (161 DK/t) amongst all lenses commercially available today. It greatly exceeds the level recommended for safe daily use and even for extended wearing of contact lenses. Furthermore, Menicon has focused on a material and lens design combination that provides a consistently higher level of averaged oxygenation across the entire cornea surface. Such attention to balancing design and material is key to providing a safer lens wearing experience. 

Maximum corneal oxygenation across the relevant areas of the lens and over the entire power range 



Minimal Lipid Deposition


 In comparison to five other popular silicone hydrogel contact lenses, 1month Miru has agreater resistance to lipid deposition in comparison to five other popular silicone hydrogel contact lenses. The greater resistance to deposition found with 1month Miru is likely to result in lower levels of discomfort, visual disturbances, inflammation of the ocular surface and lens spoilation in comparison to the other silicone hydrogel contact lenses that were examined.

Method: SiHLs were immersed in 1.5mL malten Pharmasol* for three hours at 60°C and rubbed with MeniCare Soft multipurpose solution (Menicon) 20 times. Subsequently, lipid deposition resitance was visually assessed at room tenperature.
*Pharmasol, a wax-like compound,was used as amarker for lipid deposition.

Minimal Sensitivity


Contact lenses are frequently used in conjunction with other face and eye cosmetic products,which an produce some sensitivity problems. However, 1month Miru has been found to product minimal sensitivity in such circumstances. An in-vitro study investigated the effect of cleansing agents on 1month Miru and other silicone hydrigel lenses. Overall, a greater swelling rate was observed when lenses were soaked in cleansing oils in comparison to lenses soaked in cleansing gels, although this difference was negligible for asmofilcon A and lotrafilcon B lenses. Differences between lenses in regard to swelling rate caused by the deposition and absorption of eye cosmetics might be related to differences in hydrophilic characteristics between lenses. The results of this study should help eye care practitioners to selecting the most appropriate contact lens to minimize the deformation, degeneration and swelling of silicone hydrogel contact lenses caused by deposition and absorption of cleansing agents. Additionally, the results of this study also highlights the importance of removing contact lenses before the using of cleansing agents.

For the lens care, Menicon recommends:
SOLO-CARE AQUA® multipurpose solution, with a unique HydroLock® effect and MicroBlock® antibacterial lens case, for extra-comfort and freshness, all day long.
MeniCare Soft multipurpose solution is also the perfect product for cleaning and disinfecting 1month Miru silicone hydrogel lenses.

High oxygen permeability lets your eyes breathe

Our newly developed silicone hydrogel lens material offers excellent oxygen permeability to help keep your eyes naturally healthy.

Thin edges for wettability and comfort

The uniformly thin edge design minimizes discomfort when lenses are first inserted, and helps retain moisture for enhanced wettability and all-day comfort.

Clear, clean and hygienic

Advanced lens material helps prevent protein buildup so you can enjoy clear vision all day, every day.
