Contact lenses have been garnering more and more popularity as time goes on. When compared with traditional glasses, contact lenses are incredibly convenient in many different situations. Furthermore, advanced contact lens technology should reassure people who are hesitant about the usage of these products due to health or safety concerns. Contact lenses present numerous benefits to the wearer. For instance, they provide you with a much broader field of vision than glasses are able to provide. They are much more practical in various sports, and they are not affected by the weather as glasses are. Furthermore, certain vision conditions such as aniseikonia can only be corrected with the use of contact lenses. Contact lenses can be obtained through any licensed optometrist or opthamologist. These professionals will begin by assessing your prescription needs and investigating the condition of your eyes in order to ensure that they will be able to withstand regular contact lens usage. He or she will then present you with the type of contact lens that is expected to be most suitable to your personal vision conditions. In most cases, he or she will suggest a soft contact lens as these are generally considered to be more comfortable and safer than rigid lenses; however, hard lenses are still prescribed in some special cases. It is true that some health issues can result from wearing contact lenses. The majority of these problems occur when the lenses are worn in excess; for instance, wearing your contacts overnight is strongly discouraged and can lead to many vision issues. Poor hygienic practices such as the failure to wash your hands before touching your eyes can also lead to vision damage. Vision issues commonly associated with the usage of contact lenses include damaged corneas and eyelid inflammation. However, the majority of people who wear contact lenses will not experience any problems with these products so long as the lenses are used in a safe and responsible manner. Contact lenses confer many benefits on the wearer. When compared with traditional glasses, contact lenses are consistently considered to be the more convenient and more practical choice. Although your specific vision conditions and lifestyle practices will determine the best vision correction method for you, most people would find it beneficial to research the values of contact lenses in their everyday lives. These products are a very safe and advantageous development in the world of vision correction.

Yes, I use them all the time. They will provide some lubrication to the eye without harming them. They have to be "sterile" to begin with in order not to "dirty" the eye although solution and eye drops are meant to have completely different functions.

While contact lenses are a great option for correcting vision, they are not necessarily the right option for everyone. Depending on your eyes and your lifestyle, you may find that you are perfectly happy sticking with glasses, or you may find that you need to look into LASIK surgery to correct your vision at a more permanent level. The following steps will help you determine whether it’s time to give up on contact lenses. -Step 1: If you have not worn contact lenses previously, begin by considering whether they are appropriate for your eye problem(s). If you have excessively dry eyes, contacts may not be a good option for you, or you may only be able to wear them for a few hours at a time. If you have certain vision conditions, such as presbyopia, you may need very specialized contact lenses, and it will be a matter of individual adaptation and preference as to whether they work well for you. -Step 2: If you already wear contact lenses some or all of the time, evaluate how happy you are with them. Do you find them comfortable, or do your eyes get too dry? Do you find them relatively easy to put in and take care of, or would you be happier without the cleansing and storage routine? If you’re unhappy with your lenses, you may want to either try a different kind (such as extended-wear disposable lenses), or review your other options. -Step 3: Evaluate your lifestyle. Do you frequently participate in any sport or activity that makes both contacts and glasses inconvenient, such as swimming? If so, you may want to look further into LASIK eye surgery. While contact lenses are not for everyone, neither are glasses or surgical options. If you are considering LASIK, visit your ophthalmologist and discuss whether you are a good candidate and what you can expect. The right vision solution for you will depend on your eyes and your preferences.
You can but it is not advisable nor is it safe. After the expiration date, your contact lens solution may begin to degrade; how fast will depend on the brand and chemical components of the product you use. This can mean that the pH level, which is optimal before the expiration date, will become unstable and likely more acidic. Irritation, itchy eyes, blurriness, and infection can occur with use of expired contact solution. I accidently used a 2007 solution (the current date was late 2009) and found myself with extremely uncomfortable burning vision until I realized my mistake. Consult your eye doctor always for any personal advice like I did.
Your contact lenses are a barrier between your cornea and the rest of the world. While this may not seem like a bad thing, it is. Your cornea, like every other part of the body, requires Oxygen. Too little oxygen, and complications begin to arise. So what happens when you fall asleep with your contact lenses in? Your cornea is being denied oxygen by the lens itself. This leads to a condition known as hypoxia. Corneal hypoxia changes the rate of metabolism in the epithelium. This in turn causes a decrease in glycogen, and makes the cornea more sensitive and prone to adhesion and refractive error changes. Continued progression includes corneal ulcers. Since the cornea is more adhesive, this increases the chances of any buildup on the cornea itself, including protein buildups, which cause bacterial infections and corneal ulcers. Short term effects include extreme intolerance to contact lenses. Lens intolerance can be overcome by RGP Contact Lenses, but by this point, you should just ditch them all together. Give your eyes a chance to heal, and suck it up and wear glasses.

You’ve decided that you’d like to shed the glasses and wear contact lenses. So where do you begin? First thing you need to do is make an appointment for a contact lens exam with your optometrist or ophthalmologist. This is a little different than a regular exam because your doctor will need to perform extra tests on your eyes to ensure a proper fitting for the lenses.At your appointment you will usually have a regular eye exam to measure any changes in your eyes and to get your proper prescription. The doctor will then measure the curvature of your eye. A machine called a keratometer analyzes light reflections from your cornea. These measurements are vital in finding the size and proper curve for your lenses. The doctor may also check the size of your pupil and iris. This is also done to ensure a proper fitting.You have many options when choosing the type of contact lenses you want to wear. You may choose rigid gas permeable lenses (hard) or soft lenses, but most people these days are prescribed soft lenses. Another option is disposable or non-disposable lenses. Disposable lenses may be worn one day, one week or possibly one month. Non-disposable lenses are typically worn one year and then need to be replaced. If you’re looking to change the color or your eye, you may choose to get a colored lens and some people choose to get lenses which are specially designed with logos and patterned creations for a unique look. Your eye doctor will ask you questions and help you choose the proper lenses.Typically, you will need to return to your doctor for a second visit after wearing your lenses, to ensure proper fit and check the health of your eyes. In your follow-up visit, your eye doctor may stain your eye to check for any damage to your eye surface. It is very important to keep any follow-up appointments and continue to have your eyes checked annually to ensure good eye health.
