Disposable Contact Lenses
Disposable soft contact lenses were first introduced in 1987 by Johnson & Johnson subsidiary Vistakon. They were called Acuvue. These days there are two types of disposable soft contact lenses: daily and extended-wear.
Disposable soft contact lenses do not differ from traditional contact lenses in many ways. They are made from the same materials, and both types of lens need to be replaced periodically. In the past, contact lens wearers would eventually discard their lenses. Thankfully, various cleaning solutions and disinfectants were created to extend the life of a lens. Traditional contact lenses were, and still are, too expensive to discard on a regular basis. Advances in manufacturing processes have made contact lenses cheaper, enabling wearers to discard their lenses more often. Disposable soft contact lenses are convenient, healthy, and affordable, and when cared for properly, they carry little to no risk.
Types of Disposable Soft Contact Lenses
All disposable soft contact lenses are designed to be worn for a limited time and then discarded. This is extremely convenient, since the lenses only require a minimal amount of cleaning and disinfection. The replacement schedule for disposable contact lenses can range from one day to three months, depending on how well they are taken care of and the environment in which they are worn. The most common replacement schedule is about two weeks of wear per pair.
Daily-wear disposable soft contact lenses should be taken out each day and cleaned until the replacement schedule indicates that they should be discarded. Extended-wear disposable contact lenses can be worn overnight but should still be cleaned and disinfected to prevent eye problems such as giant papillary conjunctivitis, eye infections, irritation and redness, blurred vision, and general discomfort.
Disposable soft contact lenses are more comfortable and easy to maintain because they are used until the replacement time and just thrown away. This is a significant advantage for most people who wish to wear contact lenses. New features are still being developed. For example, you can now purchase lenses with an added UV-light blocking agent. These lenses are not an adequate substitute for a pair of UV-blocking sunglasses, but some are known to block more than 90 percent of UV light.
Are Disposable Soft Contact Lenses For You?
In general, if the contact lens you desire can correct your vision problem as well as a pair of eyeglasses, you should be able to wear it. Other considerations are:
- You need to be willing to pay more for disposable contact lenses; daily disposable wearers should be aware that they will need to buy 720 lenses per year.
- Your particular prescription is available as a disposable lens.
- Disposable lenses are a great alternative for people with allergies or who naturally build up deposits on their regular lenses.
- Minimal cleaning and maintenance is required, although some form of maintenance will be needed unless you are wearing daily disposables, which are thrown away daily.
- Your eye doctor recommends this type of contact lens.
- You are willing to follow all care instructions given by your eye doctor.
Disposable Soft Contact Lenses Cost
When it comes to any type of contact lens including disposable soft lenses, you are going to pay for two things: the contact lenses and the fitting. Contact lenses can be bought from numerous locations, including your eye care provider, online retailers, optical chains, and even swap meets. Various factors determine the cost of contact lenses, such as how many you are purchasing at the time, the type of insurance coverage you have, and any specials, coupons, or rebates offered by the manufacturer or distributor. Regardless of where you buy your contact lenses, you should always have them fitted by a licensed eye care professional. Fittings vary in greatly price depending on the eye doctor, where you live, how complicated your prescription is, and the type of insurance coverage you have.
You also need to factor in the additional cost of cleaning products. Daily disposable wearers can eliminate this cost, which helps to offset the cost of the lenses.

Advantages and Disadvantages
Disposable contact lenses are extremely convenient, comfortable, and affordable. Plus, they can correct most vision problems. There are various options to choose from, making them attractive to people who once thought contact lenses were out of the question. People who do not wish to clean or disinfect their lenses daily can choose between daily disposables or extended-wear lenses. People with allergies can also benefit from these lenses, which can be thrown away before deposits build up.
Although there is a risk of complications such as eye infections, the same risk exists with traditional contact lenses. The same rules apply—no swimming with the lenses in—and even though extended-wear lenses are meant to be worn for long periods, they should still be removed and cleaned daily. The best lenses are the daily disposables. They offer the easiest maintenance, and though they are more expensive, they are still affordable.
Caring for Disposable Soft Contact Lenses
Unless you are wearing daily disposable soft contact lenses, you will need to clean and disinfect your lenses every so often, preferably daily. Never use tap water, saliva, distilled water, or homemade saline solutions to clean your lenses. These substances can contain bacteria and additional proteins that can build up on your lenses and lead to complications such as corneal ulcers.
Most daily wear contact lenses need to be taken out every night before bed. This is a great opportunity to clean and disinfect them. Some lenses require weekly enzyme treatments to remove excess build-up. Although extended-wear lenses are made to be worn for days at a time, they should still be cleaned before their scheduled replacement date to avoid complications. Sleeping with any type of contact lens increases one’s risk of infection. The best way to avoid this is to not sleep with your contact lenses in every night.

In a press release by Optician Online on May 6, 2011, it was announced that Daysoft has created the most powerful daily disposable contact lens on the market. Currently it is only available to physicians in the UK, but plans to go global are in the works. The new Daysoft 58 daily disposable contact lens has a range of high-minus -25.00D, meaning the range extends from +8.00D to -25.00D. These lenses have doubled the -12.50D power of the previous most-powerful daily-disposable lens, which was also made by Daysoft.
