Choosing the right maintenance solution and proper maintenance method for glasses is also important

★ Check if there is a license from the Department of Health. If it is approved, there will be the Department of Health Medical Device Input Number.
★ Choose the most suitable solution for wearing contact lenses, and it is best to choose a solution with high molecular weight antibacterial ingredients. Small molecule solutions are prone to getting stuck in contact lenses and slowly releasing them, which can actually harm corneal epidermal cells.
★ It is best to use a solution containing citric acid to remove protein components. This maintenance solution uses charge neutralization and ion exchange to reduce irritation compared to chemical protein removal components.
From the perspective of ophthalmologists, hard contact lenses are more effective in correcting astigmatism and myopia, especially for people with high astigmatism and irregular astigmatism. Hard glasses have a higher oxygen permeability and are less likely to cause corneal hypoxia, making them a healthier choice. However, due to the feeling of foreign objects after wearing them, the acceptance level is relatively low. Soft contact lenses have a high water content, good comfort, larger lenses than the cornea, and are less prone to detachment and displacement, making them more popular. Soft contact lenses increase oxygen permeability and comfort by increasing water content, but relatively increase the risk of allergies and infections. The latest released silicone hydrogel material has an oxygen permeability rate of over 100, similar to the hard type, making it a good choice.
