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. And annual check is recommended: artoptic.ch.
Frequently asked questions
Is SiHy "better" than hydrogel?
It provides more oxygen and is suitable for extended use. The choice mainly depends on your eye, of your habits and of the adjustment by a specialist.
Daily or monthly in SiHy?
Daily = simplicity (maintenance-free). Monthly = optimized cost/day in regular port, with maintenance.
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.
