Hard contact lenses will last you for a long time, providing you take care of them. Most contact lenses will last you longer than soft lenses, without needing to be replaced for months at a time. They are easy to clean as well, providing you know how to clean them. You can find the soaking and cleaning solution at your local department store, with several brands to choose from. This is very common, although switching to a different contact lens solution will more than likely stop the burning or irritation. Throughout the day, you may need to use rewetting drops or saline solution to keep moisture in your eyes. Sometimes, contacts can dry your eyes out, and make them feel very uncomfortable. Sometimes, contact lenses can get tears in their material, resulting in serious problems if you put them in your eyes. You should also inspect your lens for debris or smudges as well, and clean them thoroughly if you find anything wrong. If the lens is torn, you should immediately discard it and replace it with a fresh contact lens. Over the years, no-line lenses were created, and glasses became a bit more attractive. This was a very definitive time for bifocal correction lenses, as they looked a lot better than they ever did in the past - eliminating the bulky and unattractive appearance they were well known for. Now days, you can find many different types of bifocal contact lenses on the market. You have many different manufacturers as well, offering many different types, colors, and styles. Not all are suitable for you though, as no 2 eyes are the same. When you get fitted for your contact lenses, your optician will be able to help you make that decision. When you first start wearing your contacts, you should never wear them for extended periods of time. The optician or associates working there will need to verify that your test contacts meet your standards and the requirements for your eyes, according to what the optician recommends. After you have been fitted for your contacts and found the perfect pair, you should make sure that you always go to your follow up visits.
