Contact lenses and allergies

Contact Lenses and Allergies

Many patients come in this time of year complaining of contact lens intolerance.  Sensitivity to changes in the environment can cause inflammation and dryness of the eyes, but this doesn’t always mean you have to give up your contact lenses. For some patients, switching to a different cleaning solution can help rid the lens of irritating particles. Other patients may find relief by using prescription or over-the-counter allergy eye drops before or after lens wear. Daily disposable lenses can also provide increased comfort since they ensure a clean, fresh lens with each wear.

If you are having comfort or vision issues with your current lenses it is best to schedule an appointment with your eye doctor to see which of these solutions may work best for you.

The truth about your contact lens case

Contact Lens Case

While many contact lens wearers neglect to clean and replace their contact lenses as directed, many do follow the proper care instructions. However, one aspect of contact lens hygiene that is often overlooked doesn’t involve the contact lenses at all. It is the contact lens case. Some contact lens cases are brought to the eye doctor’s office looking like they are decades old, and in many cases they may be. Even if the inside wells of the case look clean, a clear biofilm from microbes builds up on the inside. This can contaminate your clean contact lenses. After applying your contact lenses to your eyes, the contact lens case should be dumped, rinsed with clean contact lens solution, and let to air dry. Perhaps most importantly, the case should be replaced every three months, just as you would replace your toothbrush.

What is exactly is your cornea?

Image of cornea

Have you ever heard the term “cornea” and weren’t sure what it meant? The cornea is the clear tissue on the very front of your eye. Contact lenses are placed directly onto the cornea. Over-wearing contact lenses can cause changes to the cornea. Some changes such as new blood vessels, scarring, and infections can be seen during routine examination. Some changes occur on the cellular level and can only be seen with a specular microscope. Having annual eye exams ensures that your corneas stay healthy.

Can a glasses prescription be used to get contact lenses?

vision wearOur patients sometimes ask us if a they can use their glasses prescription to purchase contact lenses. The short answer is no and if you see an eyecare professional that is using a glasses prescription for contact lenses, we strongly recommend that you RUN as fast as you can out of that office. A competent eyecare professional understands that taking shortcut can result in permanent vision loss for his/her patient. That said, there are several reasons why a glasses prescription cannot be used for contact lenses.

First, the strength of glasses and contact lenses are often different. This is because contact lenses sit closer to the eye and therefore don’t have to be as strong in near-sighted patients, and must be stronger in far-sighted patients. Also any amount of astigmatism is corrected in glasses, whereas astigmatism is only corrected precisely once it reaches a certain level in contact lenses, otherwise the near-sighted or far-sighted power is adjusted to account for this small amount of astigmatism.

Second, and most importantly, is that contact lenses must be matched to the measurements of the cornea that were obtained in the contact lens fitting. On a contact lens prescription the curvature and diameter of the contact lens are specified. The precise brand and material of contact lens must also be specified on the contact lens prescription. This is because all brands of contact lenses will fit, feel, and behave differently on the eye.

Most of our patients are unaware that contact lenses are a regulated medical device. Make you have a reputable eyecare professional perform a contact lens evaluation and fit. This process should take at least 2 visits to make sure that the contact lenses prescribed are right for your eye. Equally as important is to make sure you follow the doctors instructions as to how long you can wear the prescribed contact lenses and what type of solutions to use. Remember, your sense of sight is so important. Don’t risk damaging one of your most precious senses. See an professional and follow the instructions. Anyone is willing to sell you contact lenses without a proper contact lens prescription  is putting their profits ahead of your health.

Reasons you should not sleep while wearing your contact lenses!

Traditionally there have been two main reasons why sleeping in contact lenses can be dangerous. The first is that the cornea becomes starved of oxygen and new blood vessels will grow into the cornea. The blood vessels are not transparent like the cornea and will block your vision. With the arrival of the newer silicone based contact lenses that are oxygen permeable, this problem has been greatly minimized. However the other reason for not sleeping in contact lenses still exists. That is that metabolic waste products from the cells of the cornea get trapped under the contact lens while sleeping and cause an inflammatory reaction. This can lead to infections, ulcers, and scarring, all of which can lead to permanent vision loss.

You only have two eyes… vision is so important. Don’t risk harm to one of you most important senses. If you are interested in special contact lenses which are approved for overnight wear, please give us a call.

Pachymetry – Very Cool Stuff!

The optometrist will often have a patient return to the office for a special test called pachymety. This instrument using ultrasound technology will determine the central cornea thickness. This measurement is important in evaluating the intraocular pressure (IOP) for a patient who may be a glaucoma suspect. A thicker cornea results in an IOP reading for a patient that is higher than the actual pressure reading, whereas a thinner cornea will have an IOP reading lower than actual. A correction or adjustment is then applied to the IOP measurement to give the optometrist a more true reading. Pachymetry has other clinical uses involving the cornea. The thickness measurement is needed to determine if a patient is a suitable candidate for laser refractive correction or surgery. It also has a role in measuring corneal swelling from contact lens wear or from corneal disease.

Contact Lenses for BiFocals!

Many people feel that once they need a bifocal, they are unable to wear contact lenses. This is not true. In fact there are several options available. A person can wear two contact lenses for distance vision and then wear over-the-counter reading glasses over the contact lenses when reading. Another option is called monovision. In this method, a person wears a contact lenses that focuses them at distance in one eye and another contact lens that focuses them at near in the other eye. The brain learns to ignore the blurry eye not being used. The third option is multifocal contact lenses. At one point these were not very successful, however they are much better now and have a high success rate. These contact lenses let the patient view distance and near out of both eyes without any glasses.

Swimming with Contact Lenses

Contact lens wearers should not swim or use hot tubs while wearing their contact lenses. This is due to a specific type of infection to which contact lens wearing swimmers are particularly susceptible. The organism is called Acanthameoba, and is found especially in pond and lake water, but can also be in the chlorinated water of swimming pools and hot tubs. It can more rarely be found in tap water, which is why it is advised not to get water in the eyes while showering.

Acanthameoba is a single celled protozoa that has two life stages, active and cyst. Once in the contact lens from swimming, it gets into the cornea.

The infection is extremely painful, often more painful than what the eye looks like it should be. Because of its multiple life stages, it is very difficult to cure. Treatment can take a long time and multiple medications.

In severe cases, corneal transplant can be necessary.

The best way to avoid infection is to not swim in contact lenses. At the very least, wear swimming goggles to avoid getting water into the eyes. If water does get into the eyes, the contact lenses should be thrown away immediately after swimming. For this reason, daily disposable contact lenses can be the most convenient and economical option.

Importance of a Valid Contact Lens Prescription

Many people have found they can find plano colored contacts in different places without a valid prescription.  Just like the circle contacts, these contacts have not been fitted to the person’s eyes and may lead to corneal abrasions, various types of infections and potentially blindness.  The circle contact lenses are not approved for sale in the U.S., but colored contacts in various prescriptions and even in no prescription can be obtained safely and monitored safely by your eye care professional.   The next time you are interested in changing your eye color or trying something new, please call your eye doctor first.  Your eyes will thank you for it.
