All That You Want to Know About Silicone Hydrogel Contact Lenses

The present article is about what is silicone hydrogel contact lenses, about its benefits and the risks attached to them.

There are plenty people that go in for the contact lenses when they think that their eyes have begin to malfunction. Do these contact lenses work really or can prove to be problematic? What is the Science behind these lenses? Here is a complete guide.

What is Silicone Hydrogel?

Silicone hydrogel contact lenses are the latest and the most advanced type of soft lenses which allow more or more oxygen to pass through the lens to the cornea than the regular type of soft hydrogel contacts. These lenses are much more effective and with these lenses as much as five times more oxygen can reach the cornea when compared to the regular type of hyrogel lenses.

What are the Advantages of Silicon Hydrogel Lenses?

All types of contact lenses are able to reduce the extent of oxygen which reaches to the very front surface of the eye to certain degree. When oxygen supply to the cornea is reduced to a great extent, it will result in a condition known as Hypoxia. This is the condition where in the eyes begin to turn red and swell, the entire vision gets blurred and there can be an utmost level of discomfort in the eyes.

There have been hypoxia related eye issues that turned out to be a significant issue in the year 1990s when the extended wear contact lenses became immensely popular. Manufacturing contact lenses units have a tough time as a lot of people suffered from contact lens related eye-infections. This is the time when silicone hydrogel lenses were introduced in the anticipation of decreasing hypoxia related issues and enhancing the safety of the daily wear and extended wear of the soft-contact lenses.

Enhancing the oxygen supply to the eyes is very beneficial to all type of contact lens wearers. Prior to wearing any type of contact lenses, it is very important to have a word with the physician.

Specialized Silicone Hydrogel Lenses:

Increased level of oxygen permeability of silicone hydrogel contact lenses makes them a great fit for the special contact lens designs which may lead to the hypoxia issues when conventionally used soft hydrogel materials are used.

Are There Any Risk Attached With Silicone Hydrogel Contacts?

A lot of people want to know that are there any risk attached with the silicone Hydrogel contacts. According to the recent study published in the British Journal of Ophthalmology has found out that there is a very low risk of severe Keratitis among the silicone hydrogen users but they are exposed to a very high risk of non-severe Keratitis.

There have been several tests, studies and technology transfer on Hydrogel contacts. The studies have proved that the technology  of hydrogel contact lenses has proved to be very beneficial.
