Silicone Hydrogel Contact Lenses Are Widely Recommended by Medical Professionals

Let’s take a closer look at why silicone hydrogel lenses are deemed superior to other kinds of contacts.

• Increased Oxygen Permeability: All contact lenses are worn on the cornea of the eye and while lenses enable their users to see better and get past the inconvenience of spectacles, they pose a little problem. There are no blood vessels in the cornea for the supply of essential oxygen and instead, this vital part of the eye is designed in such a way that it absorbs oxygen directly from the air. Wearing contact lenses means that the cornea is no longer exposed. Silicone hydrogel contact lenses allow a greater part of the atmospheric oxygen pass through to the cornea as compared to the hydrogel, gas permeable, and rigid lenses.

• Suitable for Extended Use: Oxygen deprivation in the cornea can lead to any number of issues starting from itchiness, redness, and swelling of the eye, dryness, blurry vision to severe and irrevocable infections. That is the reason eye-care specialists recommend using spectacles along with contact lenses and remove after a certain period of use depending on the type of lens. While it is highly recommended to not go to sleep wearing any lens and to use eye drops at regular intervals, silicone hydrogel lenses help to maintain healthy and safe levels of oxygen in the eyes even with prolonged or daily wear.

• Reduced Lens Induced Hypoxia Related Issues: Hypoxia refers to the condition of oxygen deprivation in one or more parts of the body. Signs of lens-induced hypoxia include haze vision, corneal swelling, dryness, irritation, and itching, etc. This generally happens when contact lenses are worn over an extended duration. Studies show that the majority percentage of contact lens users fail to adhere to strict contact lens user guidelines. In fact, silicone hydrogel contact lenses were introduced to deal with hypoxia-related issues. By allowing more oxygen to reach the cornea even through continuous use, silicone hydrogel contact lenses help to prevent lens-induced hypoxia.

Are Silicone Hydrogel Lenses the Right Choice for You?

Without question, silicone hydrogel contact lenses in India have become popular for its oxygen permeability, especially amongst daily contact users. However, not everybody who wants to wear contact lenses needs this type. Firstly, silicone hydrogel lenses are more expensive than their counterparts. Secondly, there is some debate as to whether hydrogel or silicone hydrogel lenses are better for those with dry eyes or who need to maintain long periods of screen time. That is because some of the silicone hydrogel lens designs accumulate more protein deposits and tend to dry out the eyes much quicker than the more traditional regular hydrogel lenses. At the end of the day, whether you should opt for silicone hydrogel contact lenses or any of the other variants is better to be decided in consultation with your eye doctor as there are a number of factors to be considered and no matter, the type of contacts you wear, it is always recommended that you adhere to the standard lens wearing guidelines to maintain optic health. #siliconehydrogelcontactlenses #siliconehydrogelcontactlensesinindia #siliconehydrogellenses #siliconehydrogeldailycontactlenses #contactlenses
