Contact lenses are ingenious ocular
Contact Lenses, also known as soft contact lenses, are tiny lenses usually placed directly on your eyes. Contact lenses are ingenious ocular prosthetics worn by more than 150 million individuals worldwide, and they are worn for corrective vision or simply for decorative or therapeutic reasons. There are two main types of Contact Lenses – disposable and permanent. Disposable Contact Lenses are generally made from a variety of materials that includes polycarbonate, bicarbonate, polystyrene, carbonate, silicone, and saline. Typically, the longer the life of your Contact Lenses, the less they will cost to you.
When you wear a Contact lens, light from the sun hits your cornea and is reflected to the pupils where it is interpreted by the eye. Once an image is captured by the eye, the cornea is reshaped via surgery. After this reshaping of the cornea, the wearer is then given a new pair of prescription contact lenses. Contact Lenses come in two basic designs – either single lens or bifocal.
Bifocal Contact Lenses
You can purchase your contact lenses online or at a contact lens store near you. If you are new to wearing Contact Lenses, it is important to find an experienced optometrist to fit you for the best fit. The process of ordering your lenses online is simple and usually very reliable, but always take the time to talk to your optometrist to ensure you are ordering a good fit and that your optometrist is compatible with the online vendor. The most important thing is to be careful with your information so that you do not put yourself in a vulnerable position.
Bifocal Contact Lenses are another type of Contact Lenses that change with your prescription. The major difference between disposable lenses and bifocal contact lenses is that the latter offer a much wider range of correction. Typically, they will correct near vision as well as distant vision. A major benefit of bifocal contact lenses is that they are far more convenient than disposables – no more paper jams or having to throw away old disposables.
always wear disposable lenses
One important thing to note before deciding to wear contact lenses is that every patient has different eye needs and desires. As such, an optometrist should help you evaluate your own vision requirements before prescribing or suggesting a lens. If you have any concerns about your vision, make sure to consult with your doctor first. For instance, if you are a smoker, chances are that smoking can adversely affect your eye health. If this is the case, it would be wise to quit smoking before going in for contact lenses. This is because smoking has been known to contribute to the irregular shape of the cornea and can make wearing cornea contact lenses more difficult and time-consuming.
Another important factor to consider is that you do not have to always wear disposable lenses. As noted above, there are now many varieties of progressive contact lenses that can be worn day and night, providing you with excellent vision. Progressive contact lenses can also be worn over the course of several months – a great advantage over bifocal contact lenses. With proper care and maintenance, you can enjoy the benefits of superior vision for decades to come.
