Silver contacts are a great way to add an extra dimension of glittering glamour and sparkle to your eyes. Available in a wide range of non-prescription, fashion, cosmetic and novelty lenses, silver lenses are perfect for anyone looking to change their eye look safely and comfortably.
Silver contact lenses are not just about style; they also provide excellent oxygen flow, helping to keep your eyes healthy and comfortable. They are also extremely easy to clean with a regular lens cleaning solution.
The best way to maintain the health of your contacts is to follow a proper wear schedule and replace them when they need to be. Some people go too long between replacements, and this can result in complications like dry eye.
Inappropriate lens fitting can also lead to corneal abrasion and scarring, which can damage the integrity of the cornea. These complications can lead to corneal ulcers, a serious infection that can cause permanent vision loss.
These types of contact lenses can be made from a variety of materials, including soft and rigid gas permeable materials. In addition, they can be customized to meet the unique needs of individual patients.
Some contact lenses are designed for daily wear, meaning they should be changed each day to ensure that your eyes remain clean and healthy. Other disposable lenses are designed for quarterly or annual use and are intended to be replaced every two or four weeks.
One of the most common reasons that contact lens wearers experience complications is improper lens care. This may be due to lack of understanding about how to properly clean and store their contact lenses or because they are not familiar with the care and handling requirements for their specific type of lens.
There are a number of products that can help to keep your contact lenses clean and healthy, including contact lens cleaners that contain UV filters and disinfecting solutions. These products are usually applied to the lens with a few drops of solution on each side of the lens, and then rinsed thoroughly.
The amount of the silver nanoparticles loaded in a contact lens can affect its performance. This is because they may leak out of the lens or diffuse into the environment, causing it to become less effective.
Moreover, the dispersion of the silver nanoparticles within the lens media can vary, and this could contribute to the loss of their antibacterial activity.
Another way to improve antimicrobial protection is through incorporating antibacterial compounds into contact lenses themselves. There are a number of compounds that can reduce the amount of bacteria that adhere to contact lenses, including fimbrolides and cationic peptides.
Currently, there are a few antimicrobial contact lenses on the market that have been developed to attenuate bacterial adhesion to lenses. They include lenses that have been covalently coated with selenium molecules or octyl glucoside, both of which reduce the rate of bacterial colonization without adversely affecting the cornea. They also include lenses that have been immobilized with a polymeric substance that blocks bacteria from attaching to the surface of the lens.
