How Long Does A Contact Prescription Last

Contact lenses have changed a lot over the past few decades. They’re now available in an assortment of colors and materials that allow wearers to customize their look so they can express themselves however they want. In addition, there are dozens of different brands out there, all with varying levels of quality and price points.
If you’ve been wearing disposable contact lenses, then you know how easy it is to lose or misplace them. With monthly disposables, you’ll need to go back to your local optometrist every month to get refit checked and fitted for new ones. Not only does this take up precious time each week, but it also puts wear on your existing pairs — which could eventually lead to problems like blurry vision, eye redness and infection.
With reusable contact lenses, the process is much more streamlined. You simply purchase them at the beginning of each season (usually between $100-$300) and then you don’t have to worry about buying replacement sets until your old pair gets too beat up or worn down. The downside is that if your eyesight changes or if you have any other medical concerns, your glasses-wearing doctor will be required to sign off on your lenses before you can start using them again.
So what happens when your lenses expire? Do you have to head back to the office where you purchased them just to make sure everything’s OK? Fortunately, reusable lenses come with a limited warranty period that generally lasts anywhere from one year to two years after the day of purchase. During that time, if your frame size has changed, if your prescription has improved or gotten worse, or if you’ve had eye surgery, your doctor should check you to make sure your eyesight remains stable. If not, he or she may replace your lenses under the manufacturer’s warranty [sources: LensCrafters, Vision Direct].
Once your lenses do expire, you’ll probably want to renew them as soon as possible. Your doctor might require you to pay another visit, depending on how long ago your initial fit was and whether you’d already renewed your lenses once before. But even without additional visits to the office, it’s still important to keep your frames clean and properly cared for to ensure a healthy environment for your lenses. After all, these tiny pieces of glass sit right on the surface of your eyeball and they need to stay there safely and securely.

Contact Lenses Are Expiring All Over The World!
Although many states have adopted Daylight Saving Time schedules, some parts of the world continue to observe Standard Time. This means people in the United States won’t necessarily see Daylight Savings Time clocks change during the spring and fall months when most countries around the globe adjust theirs. And while the U.S., Canada, Mexico, Puerto Rico and several nations in Central America use the metric system, many others, including Brazil, China, Japan, South Korea and Taiwan, rely on the traditional measurement systems used by England, Australia, New Zealand and India. So, if you travel frequently, it’s always best to pack conversion charts and measuring tools in case you find yourself somewhere unfamiliar.
When you buy your contacts, you’ll receive a package that includes information about how often you should change your lenses, along with instructions for cleaning and storing your lenses. However, if you’re having trouble remembering exactly how often you should bring your lenses into the clinic to be replaced, consult a pharmacist or optometrist, who can provide specific guidelines based on your needs.
As mentioned earlier, contact lens prescriptions are usually valid for one to two years. However, if you move away from your home state or country, you may need a new set of lenses. That’s because unlike sunglasses, which typically last for one to two years, contact lenses aren’t designed to withstand extreme temperatures. As such, they can become damaged or unusable due to hot weather or cold weather conditions.
For example, although the sun shines brightly in Southern California during the summertime, its rays tend to be weaker than those found closer to the equator. This means that if you live above the Tropic Zone, you’ll likely need stronger lenses to protect your eyes from UV exposure. Although UV protection isn’t necessary everywhere, the higher the elevation, the greater the risk. So, if you plan on moving to sunny climates, be sure to ask your doctor about the UV index of wherever you’re headed.
In fact, living far below the Tropic Zone doesn’t mean you shouldn’t care about UV radiation either. Ultraviolet light is known to cause cataracts, macular degeneration and skin cancer, among other health risks. Therefore, it’s good practice to invest in protective eyewear, regardless of location, to shield your eyes from harmful UV rays.
Now that you understand how long your current lenses will last and why you need to replenish your supply, read on to discover ways to save money on your next order.
You’ll want to follow your regular schedule for replacing your contacts as well. For example, if you normally go to work Monday through Friday, you should try to switch out your lenses for the same days of the week. Also, it’s recommended that you change your lenses daily to avoid discomfort, dryness and infections.
Save Money On Contacts At Drugstores
To help you stretch your dollar further, consider shopping at discount stores rather than full-price boutiques. Although these retailers often carry larger selections, they also offer lower prices than brick-and-mortar shops. Online retailers are also becoming increasingly popular for their convenience and cost effectiveness. Most major manufacturers sell their products online directly to consumers, allowing customers to conveniently compare prices and models without ever stepping foot inside a store. To find a retailer near you, type “discount contacts” into Google, Yahoo or Bing search engines.
One way to save money on your next order of contacts is to shop around for a better deal. Make sure to ask your optometrist if they participate in mail-in rebates. Some companies offer discounts to patients who request their latest coupons via email or mail. Ask your provider if they accept trade-ins and gently used frames, too. Lastly, if you haven’t shopped for contacts in awhile, be prepared to be surprised by how low prices can range. While ordering your first batch of contacts may seem pricey, it can actually be cheaper in the long run compared to paying retail.
With some careful planning ahead, you can save money on your next order of contacts and prevent unnecessary spending. Just remember that while reusable lenses can be great for saving money, they also put extra stress on your eyesight, so be sure to talk to your eye care professional about the pros and cons associated with your particular situation.
