Since the introduction of contact lenses years ago, the eye product has gone through various changes and innovations to meet the needs of the consumers. There are now more than ten types of contact lenses each with its own characteristics. You can get a prescription from an eye doctor and decide on your own which specific brand and type of lenses you want. If you find the task difficult, you can also ask the doctor for his suggested brands and contact lens type. The following are the types of contact lenses you can use depending on your needs and preferences:
&bull Daily wear soft lenses - made of soft polymer plastic, these contact lenses allow oxygen to pass through providing a higher level of comfort than rigid gas permeable lenses. Disposable soft lenses fall also under this category. They are called daily wear contact lenses because they require daily cleaning. Although most daily wear soft lenses are disposable there are also those that can be worn for one whole year. Disadvantages of these types of lenses include: easy absorption of oils and lotions from your hand which can irritate your eyes and also less durability than hard lenses
&bull Disposable soft lenses- disposable soft lenses can be worn up to two weeks. They still require daily cleaning but they are not designed to last you months.
&bull Daily wear disposable lenses- daily disposable lenses are lenses which you can only use for one day. They are discarded at days end. Although daily disposables are more affordable than yearly lenses, expenses can add up when you buy a year's worth of disposable lenses. Using daily wear disposable lenses lowers your risk to eye infections.
&bull Colored Soft Lenses- Colored soft lenses are perfect for those who want a fresh look. They serve the same purpose as color contact lenses except they do come in different tints. Some colored lenses contain tints not for aesthetic purposes. These light-filtering tinted lenses are for athletes or sports enthusiasts.
&bull Extended-wear lenses- Extended-wear lenses are contact lenses that can be worn for several weeks, usually 30 days without having to remove them. They can come in either soft or gas permeable types. They are perfect for busy people who do not have the time to clean their lenses at the end of each day.
&bull Daily wear rigid gas permeable lenses- these contact lenses are made of plastic that are not as soft or as absorbent as soft contact lenses but they allow oxygen to pass through them. They don't tear as easily as soft lenses do but they can take a few weeks to get used to. These type of lenses also require daily cleaning.
&bull Bifocal contact lenses - are solutions for those who are suffering from presbyopia.
&bull Toric Contact Lenses- this type of lenses are used to correct astigmatism. These contact lenses are also bi-focal. And can be made from soft lenses or gas permeable materials.
&bull Orthokeratology lenses- these lenses are used for improving vision problems caused by the cornea's shape. These lenses when worn overnight adjust the shape of the cornea so that the individual can have food eyesight the following day for up to 12 hours.
Contact lens is a medical device, a thin lens specially designed to fit over the cornea. It is usually worn to correct vision defects. Several people have resorted to wearing this sometimes fancy contact lens to feel more comfortable over using thick eyeglasses or to do away with any eye operation which could be more costly. But before deciding to buy your own, here are a few tips that you should do to get the best contact lens for the windows to your soul.
A medical opinion is a must! Deciding on whether or not it would be best for you to use contact lens should be drawn from a medical advice. An eye care professional must recommend or advise that you use these devices. Request for an eye examination. In this way, the doctor can be objective with his advice. The shape of your eyes should be determined because there are shapes that cannot hold contact lenses. Secure a prescription as necessary because buying without a prescription will only put you at risk should you have problems with your orders in the future.
Keep yourself up to date! Check if you have a valid or current prescription otherwise retailers will not honor your order. Over-the-counter purchases in the absence of a prescription are a violation of FTC regulations and cannot protect you as well when complaints should arise. Your prescription must be complete and must not be expired. Double check expiration dates on the product; expired contact lens could only damage your delicate eyes.
Gather information. As always is the case, being informed yields to a more satisfying decision. Know the range of prices and how much you are willing to pay for. There are contact lenses that are expensive and may not give value for your purchase. Verify with the sales personnel that your order is approved by FDA. That's one way of getting value for your purchase. If your insurance can cover this expense, that would be a better way to put it through.
Check availability! You should know if your orders are available because you will need to wear them once your doctor advised you need to get one. If in the future you also need to use the same type and your recent lens have been worn out then, you can readily check its availability.
Advancements have made contact lens for longer use. Check the type of contact lens that you will need if you have to wear it for a long time or if you want to put it overnight.
There are numerous means to buy. Check how much time you have to do all the decision making and buying processes. Choose whatever is most convenient for you. Remember though that your eyes are very delicate and taking care of it requires utmost care and attention. Take some time to do your homework and avoid any regrets later on. Your eyes are so much worth your time. Ordering has become so much easy these days. Go online and check your options. You can even have them right at your doorstep!
