Which Silicone Hydrogel Lenses Should I Buy?

  “What contact lens content is the best?” says the narrator. Any contact lens wearer, particularly those with dry eye syndrome, has had a concern.
  • “How essential is water content material in contact lenses?”
  • “Should I select hydrogel or silicone hydrogel lenses?”
  • “Which material is excellent for my subtle eyes?”

What kind of smooth contact lenses are there?

Nowadays, most contact lenses are both made of hydrogel or silicone hydrogel.
Both compounds have advantages and disadvantages. 

Hydrogel Contact Lenses

 Hydrogel lenses are plastic gel-like lenses that contain water, called hydrogels. These lenses are fragile and flexible and follow the surface of the eye. 
Hydrogel lenses were first developed in the early 1970s. And their convenience and ease of use helped to boost contact lens acceptance.
  When it comes to dry eyes, a hydrogel lens is forever the best feature.
 Water evaporates from hydrogel lenses, making the cloth even less comfortable. 
  • Comfortable and long-lasting
  • The human eye is biocompatible with this soft lens material.
  • Suitable for those with sensitive eyes


  • Oxygen absorption has decreased.
  • Less relaxed after many hours of wearing
  • Less elastic than silicone hydrogel

What are Silicone Hydrogel Lenses

Silicone hydrogel lenses are a more flexible kind of soft contact lens. They allow more oxygen to penetrate the cornea.
Introduced in 2002, it is an addition of hydrogel and silicone. It is viable for the producer to amplify the oxygen permeability, even with a low water level.
  Modern silicone hydrogel lenses permit extra oxygen, reducing the hazard of eye hypoxia. They have got a sturdy urge to put on something for the long term due to this trait.
These lenses have a lower wettability stage and are more prone to large deposits.

Benefits of Silicone Hydrogel Contact Lenses

Silicone hydrogel lenses offer a high level of comfort and hydration during the day. Silicone hydrogel lenses are suitable for weekly and monthly contact lenses. They ensure that the lenses stay shiny and moisturized throughout their athletic period. 
 Wearing silicone hydrogel lenses over more extended periods is more convenient. It is helpful for those who lead active lives, long waste periods staring at a phone or are prone to dry eyes. 
Because of their increased comfort, they can also be used as extended-wear lenses. One can wear these lenses all day and night without being removed for up to a set period (one week to a month). 
Since they drop the bother of washing contact lenses, they are perfect for those who have a busy life. If you decide to go with these, you can consult an optician to ensure that they are appropriate for you.

Let’s talk about contact lens materials with high water content.

Contact lenses are also classified into three groups based on their water quality.
  • Low water content material (up to 45%) – silicone hydrogel contact lens, meant for nonstop wear. They have a hundred percent oxygen (the ability for liquids and gases to flow through).
  • Hydrogel contact lenses with a midwater content (up to 60%) suitable for most consumers.
  • Hydrogel contact lenses with a high water content (up to 90%) for more excellent touchy eyes.

Water Content and Oxygen Transmissibility (Dk/t)

The ratio of permeability of your lenses is proportional to their water content.
The more water in the cornea, the more difficult it is for oxygen to reach the cornea. It also works the other way around: the more permeable a substance is to oxygen, the less water can bind to it.
So, if your contacts are moist, they will be blissful and convenient to apply. But bear in mind that water evaporates from your contact lenses over the day.
If this occurs, your eyes ought to end up dry. You can experience discomfort, as well as itchiness and a burning feeling. So many people who wear contact lenses believe that the more water they drink, the better their eyes.
Moisture so isn’t the only thing our eyes need to remain safe. Our eyes need oxygen. So when selecting contacts, you should always seek the advice of an eye doctor or Optometrist. Both wettability and breathability are essential. It’s about finding the right balance.

Silicone hydrogel lenses are the most common type.
