Long gone are the days of dry contact lenses and itchy eyes. Thanks to the advances made in contact lens technology and materials, the most modern lenses incorporate silicone hydrogel, a material that allows more oxygen to your cornea, so your eyes can feel and stay hydrated even after a lengthy day.
Contact lenses made of silicone hydrogel can help alleviate dry eyes. So, if you currently experience dry eyes while wearing contacts, you may want to ask your Optometrist if you are suited to wear silicone hydrogel contacts.
The technology behind silicone hydrogel contacts
As its name indicates, this type of contact lens is comprised of silicone and hydrogel materials.
Silicone is a chemical compound that allows higher levels of oxygen to pass through the surface, as compared to other regular soft contact lenses that are primarily comprised of hydrogel.
Hydrophilic gels, or hydrogels, on the other hand, are compounds that contain mostly water content which help to hydrate your eyes.
Today, there are several different types of silicone hydrogels that are used to manufacture contact lenses. The wear and replacement cycles of these contacts are dependent on the specific silicone hydrogel they are made of.
The benefits of silicone hydrogel contacts
By combining silicone and hydrogels, this type of contact lens provides increased oxygen permeability and surface wettability, making them optimal for dry eyes.
As your cornea receives additional oxygen and the surface of the contact lens retains moisture, you’re left with improved breathability, hydration, and comfort.
This makes silicone hydrogel contact lens ideal for longer periods of wear, with certain brands allowing for up to 12 hours of wear.
A new line of contacts
At Clearly, we now have a new, exclusive line of everclear contact lenses that are constructed of silicone hydrogel materials:
i.everclear Elite daily contacts are designed for up to 12 hours of wear. Available in 5 pack, 30 pack and 90 pack.
ii. everclear Air monthly contacts are designed for easy applications. Available in 1 pack and 3 pack.
iii. everclear Plus bi-weekly contacts are available in 1 pack and 6 pack.
iv. everclear Active daily contacts are designed for active lifestyles.
As contact lenses made of this material may not be suitable for everyone, it is important to consult your Eye Care Professional to determine the right type of contact lenses and schedule for you.
