Comfortable wearing with silicone hydrogel contact lens
Posted by SEOTech on December 22nd, 2020
Silicone hydrogel contact lenses are specially designed soft lens, similar to standard hydrogels of lenses made of plastic material that is hard when dry but readily absorb water and become soft. This contact lenses enable five times more oxygen to pass through the lens to the cornea of the eyes than regular soft contacts.
If you have ever let a soft or silicone hydrogel lens dry out, you know that it becomes deformed, hard and fragile. But if you soak it for a few minutes in contact lens solution, it becomes soft and pliable again. Silicone is a very common mineral. Silicone hydrogel lenses are soft lenses, but Silicone is also used in the production of many gas permeable contacts to improve oxygen permeability of the lenses. It is an extremely flexible material, which makes it excellent for making not only contact lenses but many other medical products such as implants and tubing. Silicone hydrogel contact lenses have numerous benefits. Let’s discuss some of them.
Silicone hydrogel lenses can be worn more comfortably for longer periods. This is especially helpful for those who live active lifestyles, spend long periods looking at a screen working on computers or laptops, who are easily susceptible to dry eyes. Silicone hydrogel lenses offer an increased level of comfort and hydration throughout the day when wearing lenses. It ensures that your lenses remain fresh and hydrated throughout their entire wearing circle, could be for two weekly and monthly.
Silicone hydrogel contacts help minimise problems like redness, dryness, swelling of the cornea, corneal infection. And any infection that does appear tends to be less aggressive and more treatable. Silicone hydrogel lenses allow more oxygen to which the cornea, which improves eye health. Silicone hydrogel lenses include more resistance to protein deposits, less drying of the lenses, lower risk of infection, easy handling due to the greater rigidity of the material, and high dk levels which remove the risk of conditions like hypoxia to the cornea.
There are many different types of silicone hydrogel materials that are each used to make contact lenses that address different corrective and wearing needs. There is no hard evidence that the increase in oxygen supply to the eye when wearing silicone hydrogel lenses improve end of the day wearing comfort, compared with wearing regular hydrogel lenses.
So, why knowing the benefits of silicone hydrogels can help inform your preferences, you should choose the right contact lenses for you by consulting your eye doctor, and evaluating the wear and replacement schedules are contact lenses are approved by some authority or Technology transfer.
