Silicone hydrogel lenses — high oxygenation & extended wear

The silicone hydrogel (SiHy) lets significantly more oxygen pass throughDk/t) than the classic hydrogel. He is appreciated for long days, intensive use (screens, air conditioning, sports), and certain professional indications.

Benefits

• Superior oxygenation helps to limit corneal hypoxia.
• More stable comfort at the end of the day for many carriers.
• Large offer in spherical, toriques, multifocal, in daily And monthly.

Points of attention

• Trend towards lipid deposits for certain profiles → routine ofinterview adapted.
• Modulus plus "close" initial sensation sometimes more pronounced than with the hydrogel.
• Price often a little higher.

When to choose SiHy?

• Long days / need for maximum oxygenation.
• Searching for more stable comfort at the end of the day.
• Astigmatism or presbyopia with available SiHy options.

Always follow your specialist's advice and the manufacturer's instructions. annual check is recommended: artoptic.ch.

Silicone hydrogel — high oxygen permeability & long wear times

Silicone Hydrogel (SiHy) allows significantly more oxygen (Dk/t) occur as a classic hydrogel. Ideal for long days, lots of screen time, and demanding carrying profiles.

Advantages

• More oxygen → lower risk of hypoxia.
• Stable comfort until the evening
• Wide range of products spherical, toric, multifocal; daily and monthly lenses

To be noted

• Lipid deposits with some carriers → suitable Care.
• A somewhat firmer material as hydrogel (adaptation).
• Price sometimes a bit higher.

When are you free?

• Long retention times / maximum oxygen supply desired.
• Seeking stable late-day comfort.
• Toric or multifocal available in SiHy.

Please follow the recommendations of the specialist and the manufacturer's instructions. Annual check recommended: artoptic.ch.

Silicone-hydrogel — high oxygenation & prolonged use

He silicone-hydrogel (SiHy) let more oxygen pass throughDk/tCompared to the classic hydrogel. Suitable for long days, lots of screen time, and intensive ports.

Advantages

• Superior oxygenation → lower risk of hypoxia.
• More stable comfort Have a good day.
• Wide selection spherical, toric, multifocal; daily and monthly.

Attention

• Lipid deposits in some carriers maintenance adequate.
• More "rigid" material of the hydrogel (initial sensation).
• Price sometimes higher.

When to choose SiHy?

• Prolonged use / maximum oxygenation.
• More stable evening comfort.
• Toric or multifocal lenses available in SiHy.

Follow the specialist's and the manufacturer's instructions. Annual check-up recommended: artoptic.ch.

Silicone hydrogel — high oxygen permeability & longer wear comfort

Silicone hydrogel (SiHy) delivers much higher oxygen (Dk/t) than classic hydrogel. Idéal pour les longues journées, les longues périodes devant l'écran et les routines exigeantes.

Pros

• Superior oxygen → helps reduce the risk of corneal hypoxia.
• Plus de confort plus stable en fin de journée pour de nombreux porteurs.
• Large portfolio (spherical, toric, multifocal; daily & monthly).

Cons

• Dépôts lipidiques can be more frequent → customized care.
• Higher modulus than hydrogel (initial feel).
• Souvent plus cher.

When to choose SiHy?

• Extended wear hours / need for high O2.
• Cherchant un confort plus stable en fin de journée.
• Options toric ou multifocales requises.
