Silicone Hydrogel Contact Lenses

About Silicone Hydrogel Contacts

One of the main concerns for those who wear contact lenses is comfort. For decades, many contact lens wearers found that they just couldnít endure the discomfort that was typically associated with contacts. This began to change in the 1960s and 70s when the first soft hydrogel contact lenses were launched. These soft contact lenses improved oxygen permeability, lens wettability, and overall comfort for wearers. Despite these advances, it wasnít until 1998 that silicone hydrogel contact lenses became available to the public and contact lens comfort became commonplace.

Silicone hydrogel contacts have an extremely high oxygen permeability, with up to five times more oxygen reaching the cornea than with traditional hydrogel lenses. In 2013, silicone hydrogels accounted for 66% of all contact lens fittings in the U.S., compared to only 24% for regular soft contact lenses. The popularity of silicone hydrogel contacts is due to their effectiveness and higher levels of comfort relative to other types of contacts.

Silicone hydrogel contacts enable lens wearers to keep their lenses in for longer periods of time, known as extended wear, with a much lower risk of hypoxia. Hypoxia is when the corneaís oxygen supply is significantly reducedóhypoxia is responsible for problems including red eyes, corneal swelling, blurred vision, and general eye discomfort. It can also increase the risk for a number of different eye infections. By significantly increasing the amount of oxygen that reaches the cornea, silicone hydrogel contact lenses increase the safety of both daily wear and extended wear of soft contact lenses.

Silicone hydrogel contact lenses are also useful in the design of specialty contacts. For example, the greater lens mass necessary for the design of toric lenses benefit from using silicone hydrogel material. This has enabled contact lens manufacturers to develop a wider variety of lens designs while still ensuring a healthy amount of oxygen reaches the cornea. Many of the most popular brands of contact lenses are silicone hydrogels including Acuvue Oasys, Air Optix Aqua, and Biofinity. The best way to determine if silicone hydrogel contacts are the right choice for you is to discuss all possible contact lens options with your eye care professional.

Frequently Asked Questions

What is the difference between hydrogel and silicone hydrogel?

Hydrogel lenses were some of the first lenses made of soft materials, specifically water-containing plastics called hydrogels. They have a naturally high water content and may be suitable for dry and delicate eyes.

Silicone hydrogel lenses are an advanced type of soft contact lenses that are more porous than regular hydrogel lenses and allow even more oxygen to reach the cornea than hydrogel-based lenses. This feature makes them a great choice for extended wear, and an excellent choice generally.

Why is silicone hydrogel popular?

The most significant benefit of silicone hydrogels is that they allow up to five times more oxygen to reach the cornea than regular hydrogel lenses. Without a healthy oxygen supply, the eyes can become dry and itchy, and vision may begin to blur - a condition known as hypoxia.

Which contact lenses are silicone hydrogel lenses?

Silicone hydrogel lenses include the Acuvue Oasys, Biofinty, Dailies Total 1, and Air Optix line of contacts, each of which are extremely popular choices amongst wearers and ECP's alike.

Are silicone hydrogel contacts safe?

A majority of all contacts sold in the market today are silicone hydrogel-based, so by that measure, they can be considered safe. However, this is a broad question directed to a specific situation. No single solution is perfect for every individual. There are distinct benefits to silicone hydrogel lenses, including their superior oxygen transmissibility, however some users have reported increased sensitivity, deposit, or general discomfort. Some users prefer the older hydrogel-based contacts. If you're looking for contacts with some of the most advanced comfort features available, silicone hydrogel lenses need to be considered.

Focus Night & Day

Monthly Disposable

These work well for me as i am a convenience whore. For several years with the blessing of my eye Doc, I put them in and leave them for a month. I use wetting drops in the morning and again at night. I am sure to go three or four days at the end of the month with no contacts in just to let my eyes rest and recover. These are perfect.
