Today’s contact lenses have become a staple due to their versatility in the modern lifestyle. Technological advancement in modern eye care has ensured that almost anyone can wear contacts comfortably. Some people prefer lenses over eyeglasses while others claim that they are cumbersome and irritating. Selecting appropriate contacts is an important decision that may require the input of a professional.
Simply put, contacts are thin plastics worn over the eyes to correct particular vision problems. They offer a perfect solution to people who do not want to have surgery to correct their eye problems or wear cumbersome eyeglasses. Countless people use contacts as their corrective eyewear of choice, especially those who have an active lifestyle but want crisp vision without using a pair of glasses. Such people are incredibly grateful to don contacts and enjoy the freedom they offer!
Before deciding to order contacts, it is important to find out if you need to have them in the first place. Those who are interested in wearing contacts should first undergo a lens exam by an eye specialist. During the examination, your eye specialist will first seek to determine whether your eyes are healthy enough to wear contacts. Part of the exam will also involve eye measurements so that you are fitted with contacts that are comfortable and the right size for your eyes. The eye doctor also assists first time users on how to put in and take out lenses correctly and how to take care of them.
Contacts are divided into two broad types: rigid gas permeable and soft contacts. Soft contacts are usually made of water which is the reason why they are soft. They are extremely thin and comfortable to wear. Soft contacts are further subdivided into four basic groups: regular or spherical, contacts made for astigmatism, cosmetic or color, and contacts for presbyopia. Rigid gas permeable contacts are usually made of tough plastic which enables them to correct vision problems. These contacts are more durable, unlike their soft counterparts.
Generally, your choice of the type of contact will be based on several factors such as your expectations, refractive error and the length of time your eyes can tolerate the lenses without getting affected by them. Ordinarily, contacts can be worn comfortably either part time or full time depending on the special needs of the person. When selecting the most appropriate eyewear, you need to consider the following choices:
This type of eyewear is usually the least expensive. However, such lenses have to be removed and disinfected every night. They also need to be replaced regularly depending on brand and type. Replacement period varies from a fortnight to every three months.
Daily disposable lenses are meant for single use and are usually discarded once the day is done. The only downside to these lenses is that they end up being expensive since you need a new pair daily. However, they offer more convenience and decrease the risk of infection or irritation of the eye. Weekly or monthly disposables also require the same treatment once their time lapses. Disposable contacts are considered as the best option for people who have allergies and other complications that can be aggravated due to protein formation from tear film.
Extended wear contacts are designed to be worn overnight although they need to be removed regularly to be cleaned and disinfected. These lenses are frowned upon by most eye doctors since they reduce the amount of oxygen reaching the eyes thus making them more vulnerable to infection.
Multifocal lenses are for those who have a condition referred to as presbyopia. As we age, the lens of the eye progressively loses its ability to change, making it hard to focus on objects close to us, making it difficult to see. This is referred to as presbyopia. Bifocal or multifocal lenses usually correct such problems effectively.
Toric eyewear is ideal for correcting astigmatism, which results in blurred vision. On the other hand, colored lenses are often worn for cosmetic purposes since they change the color of the eyes dramatically.
Most people find wearing contact lenses quite a rewarding experience although some eventually stop using them due to discomfort or irritation. Usually, this discomfort is caused by environmental contaminants such as sprays, dust, and smoke. Use of antihistamine, alcohol, air travel or birth control pills usually causes eye irritation. Pinpointing the root of the irritation is usually one of the effective methods of eliminating such discomfort to guarantee the convenience of wearing contacts. Once the cause of the irritation is identified, adjustments can be made to reduce any trouble, and contacts can again be worn safely and comfortably.Tags: contact lens, daily wear, disposable, extended wear, eye care, measurements
