Why Silicone Hydrogel Lenses Are a Game-Changer for Eyes
Are you a contact wearer? If so, then you’ve been hearing the buzz about silicone hydrogel contact lenses, you’re not alone. These high-tech lenses are a game-changer for anyone who wears contacts.
However, the big question so many are wondering is - “What exactly is silicone hydrogel, and why is it so great for your eyes?” In this article, we will explore the answer to that big question and also look at how silicone hydrogel can benefit your eyes.
What is Silicone Hydrogel?
Silicone hydrogel is a type of soft contact lens material that allows more oxygen to pass through the lens to your cornea compared to traditional hydrogel lenses. This material is super breathable, which is a big deal when it comes to keeping your eyes healthy and comfortable.
Regular hydrogel lenses are made of a water-containing polymer that provides some oxygen permeability, but not nearly as much as silicone hydrogel. By incorporating silicone into the mix, manufacturers created lenses that are both flexible and highly oxygen-permeable.
Why Oxygen Matters
Okay, so silicone hydrogel lets oxygen more readily reach your eyes but why is that a game changer for your eye health?
Your eyes need oxygen to stay healthy. When you wear contact lenses, they sit directly on your cornea, which can limit the amount of oxygen that reaches your eye.
Without enough oxygen, you can experience discomfort, dryness, and even more serious complications like corneal swelling or infections. If you suffer from dry eyes, check out our blog post on wearing contacts in dry climates.
Silicone e hydrogel lenses let up to five times more oxygen reach your cornea than traditional lenses. This increased oxygen flow keeps your eyes feeling fresh and comfortable, even if you wear your lenses for extended periods.
Did you know that your corneas don't have any blood vessels? Because our corneas absorb oxygen directly from the air, they must have unobstructed access to it. The rigid contacts of the 1970s didn't allow for this, which meant they could only be worn for short durations.
However, as technology has advanced, so has the oxygen permeability of contact lenses, measured by what's known as “Dk/t.” The higher the Dk/t number, the more oxygen the lens allows to pass through. This improvement, along with other advancements, makes wearing contacts for longer periods much more comfortable.
Silicone hydrogel lenses, in particular, provide significantly higher oxygen transmission (that’s the “Dk/t” number) compared to standard hydrogel lenses and certainly surpass the rigid glass contacts of the past.
Benefits of Silicone Hydrogel Lenses
Now that we know what silicone hydrogel is, let’s talk about the benefits - there are many benefits to silicone hydrogel lenses.
Why should you consider switching to these lenses?
All-Day Comfort
Because silicone hydrogel lenses allow so much oxygen through, they’re incredibly comfortable which makes them great for all-day wear. Many contact wearers report that they can wear these lenses for longer periods without experiencing dryness or irritation.
Reduced Risk of Eye Problems
The increased oxygen permeability reduces the risk of complications like corneal hypoxia (lack of oxygen), which can lead to serious eye conditions. With silicone hydrogel lenses, your eyes stay healthier, and can easily breathe.
Studies have shown that silicone hydrogel contacts significantly reduce the frequency of dry eyes.
Great for Sensitive Eyes
If you have sensitive eyes or suffer from dry eye syndrome, silicone hydrogel lenses might be your new best friend. They help maintain the moisture balance in your eyes, reducing irritation. You can enjoy all-day comfort without the sensitivity.
Extended Wear Options
Some silicone hydrogel lenses are approved for extended wear, meaning you can sleep in them (although it’s always best to consult your eye doctor before doing so), according to the Food and Drug Administration (FDA). This convenience is a huge plus for people with busy lifestyles.
Clearer Vision
Studies have shown that silicone hydrogel lenses can provide sharper and more stable vision, especially if you have astigmatism or other refractive errors. They maintain their shape better, leading to more consistent vision correction.
Who Should Use Silicone Hydrogel Lenses?
Silicone hydrogel lenses are a great choice for almost anyone who wears contacts, but they’re especially beneficial for:
- People Who Wear Contacts All Day: If you wear your lenses for more than 8 hours a day, Silicone hydrogel lenses can help keep your eyes comfortable.
- Dry Eye Sufferers: If you struggle with dry eyes, these lenses can help by allowing more oxygen to your cornea, and keeping your eyes hydrated.
- Active Lifestyles: If you’re always on the go and need lenses that can keep up, silicone hydrogel is a solid choice. They’re durable, comfortable, and great for extended wear.
How to Care for Silicone Hydrogel Lenses
Caring for silicone hydrogel lenses is pretty straightforward, but there are a few things to keep in mind to get the most out of them:
- Follow the Wear Schedule: Even though these lenses are super breathable, it’s important to follow the wear schedule recommended by your eye doctor. Don’t push them past their intended wear time.
- Clean Them Properly: Just like with any contact lenses, proper cleaning is key. Use a solution that’s compatible with silicone hydrogel lenses, and avoid using water to clean them.
- Store Them Correctly: Always store your lenses in a clean, dry case with fresh solution. Replace your lens case every three months to avoid contamination.
- Stay Hydrated: Drinking plenty of water helps keep your eyes hydrated, which can enhance the comfort of your lenses.
Silicone hydrogel lenses are a fantastic option for anyone looking to upgrade their contact lens experience. They offer superior comfort, better eye health, and the convenience of extended wear.
