Why silicone Hydrogel Lenses are Preferred instead of Normal Contact Lenses?
Most optometrists for kids and ophthalmologists agree that one of the most important advantages of silicone hydrogel lenses is the reduction of hypoxia-related problems related to soft lenses that are made up of standard hydrogel materials. Many times, Eye contact lens wearers inform their doctors about developing allergy-like symptoms because of wearing contact lenses. The most common complaints are redness, discomfort, itchy eyes, and greater lens awareness or dryness symptoms. However, these symptoms can also rise because of contact lens dryness or sensitivity to a new contact lens solution or care routine. Though silicone hydrogel lenses let more oxygen to reach at the surface of the eye, the added silicone can lessen the surface wettability of the lenses, potentially making it more laborious for them to stay hydrated on the eye.
