Differences Between Silicone Hydrogel and Hydrogel Contact Lenses
Contact lenses come in various materials, with the most common being silicone hydrogel and hydrogel. Today, let’s look at the main differences between these two materials and which one might be more suitable for you! 👇
1️⃣ Water Content 💦
Silicone Hydrogel: Although it has a lower water content than hydrogel, its high oxygen permeability compensates for the lower moisture level, effectively retaining moisture and enhancing comfort.
Hydrogel: Has a higher water content, but for those with dry eyes, it may feel even drier. Therefore, it’s essential to consider your eye condition when choosing.
2️⃣ Material and Wear Difficulty 🧰
Silicone Hydrogel: Generally stiffer, making it easier for first-time wearers to put on, but some may feel discomfort if they’re not used to it. However, the latest generations are more breathable, making the wearing experience nearly indistinguishable from hydrogel.
Hydrogel: Relatively soft and easy to adapt to, making it less likely to feel like a foreign object.
3️⃣ Price 💰
Silicone Hydrogel: Usually slightly more expensive, but the price difference is not too significant, making it a worthwhile investment.
Hydrogel: Generally more affordable, suitable for those on a budget.
4️⃣ Oxygen Permeability 🌬️
Silicone Hydrogel: Has an oxygen permeability of 100 Dk/t or higher, allowing for long wear without issues and effectively reducing eye fatigue.
Hydrogel: Has lower oxygen permeability, which may lead to fatigue after extended wear.
Summary
When choosing between silicone hydrogel and hydrogel contact lenses, consider your individual needs and wearing habits. If you frequently wear contact lenses and want better breathability and moisture retention, silicone hydrogel may be the better choice. However, if you prefer a softer, more comfortable feel, hydrogel is also a great option. I hope this information helps you find the most suitable contact lenses!
