People who wear contact lenses are primarily concerned with the softness and water content of the material. The comfort you would be enjoying while wearing these lenses directly depends on its nature. Silicone hydrogel lenses have gained popularity over the years, as they are soft and have the ability to absorb water. Presently, many people are buying silicone hydrogel lenses online. This special kind of lens enables a greater amount of oxygen to reach the corner through the lens, as compared to the normal hydrogel lens. With the right kind of silicone hydrogel lens, your corner can get as much as five times more oxygen.
What are the benefits of silicone hydrogel contact lenses?
Almost all types of contact lenses tend to minimize the oxygen content reaching the frontal eye surface to some extent. In the process, the overall amount of oxygen reaching the corner gets reduced to a significant extent. This may lead to hypoxia, a condition leading to several issues like swelling of the cornea, red eyes, discomfiture, and blurred vision. Besides, it exposes the eyes to a number of other risks.
With the inception of contact lenses during the 1990s, problems related to hypoxia increased manifold. The prime reason for using silicone hydrogel lenses is that they can reduce these problems and enhance the safety of the user. These lenses are soft and permit a greater volume of oxygen to reach the eye. In many cases, the users do not adhere to the instructions of the doctors regarding a replacement. Wearing silicone hydrogel lenses reduces these issues significantly.
Silicone hydrogel contacts can carry a greater amount of oxygen. For people suffering from issues related to hypoxia, these lenses prove beneficial.
The material
Silicone hydrogel lenses are made of plastic. When it is dry, the material becomes hard. However, these lenses have the ability to absorb water readily. In the process, they can become hydrated and it gives a soft, gel-like touch. This type of lens may become hard, fragile, and deformed when you dry it out.
However, it becomes pliable and soft again, when you place it in a solution for a few minutes. Due to the various advantages of silicone hydrogel daily contact lenses, people have been using them extensively. Check out the best lenses online and make the purchase.
You must note, that silicone hydrogel contact lenses are mistakenly referred to as silicon lenses at times. Silicon refers to a common mineral. However, silicone hydrogel contact lenses are flexible and plastic-like. It contains oxygen, carbon, silicon, and other chemicals. These contact lenses come with a greater degree of oxygen permeability.
Should you wear silicone hydrogel lenses?
Most of the ophthalmologists and optometrists recommend wearing silicone hydrogel lenses. The reason is this kind of lens help in the mitigation of issues related to hypoxia. Therefore, they are less likely to lead to problems in the eye, like discomfort, red eyes, and keratitis.
People can wear silicone hydrogel lenses for a longer duration, as they come with greater oxygen transmissibility. Some people tend to sleep wearing their lenses. For them, silicone hydrogel daily contact lenses would be the ideal option.
However, if you have delicate eyes, this kind of lens may not be suitable for you. You should have a word with your ophthalmologists before you finally purchase one. Besides, some of these lenses contain greater deposits. They may not be ideal if you are intolerant to silicone.
