We contradict 5 false myths about contact lenses


Are contact lenses difficult to use? Can they slip behind the eye? Are all of them expensive? These are some of the rumours that exist about contact lenses.

Incorrect rumours that take away supporters to a treatment option of visual problems with many advantages. Biòptic explains to you the truth about contact lenses contradicting 5 myths, one by one.

 1. Do contact lenses play the same function as glasses?

Many people believe that contact lenses can only be used for certain visual problems, but these can actually correct all the visual problems, such as myopia, astigmatism, hyperopia and even presbyopia. The design of the contact lenses for presbyopia has advanced so much so that it exists contact lenses with progressive designs that allow to see at near and far distances. In fact, the contact lenses have the same function as glasses with the advantage that the visual area amplitude increases.

2. Are contact lenses uncomfortable, difficult to put on and maintain?

Since years ago, contact lenses are being made with a soft material, that allows great comfort. Moreover, your optician-optometrist will recommend you the adequate  type of contact lense according to your eye parametres. Depending on the hours you have to use them daily, the meaures of your eye and the graduation, the contact lense will be one or another.

To put on and to maintain them turns out to be easy with the advice of your optician-optometrist. Many of the designs nowadays are disposable, which allows one to wear for the first time contact lenses every day. The maintenance is very easy thanks to the multipurpose solutions.

3. Is my age appropriate to wear contact lenses?

To be able to wear contact lense does not depend on the age! The market offers a wide variety of contact lenses and therefore we can find appropriate contact lenses for all ages.

Many adult people prefer glasses because of an aesthetic question and others, such as sportsmen, because of a practical and security question, since there is no risk that contact lenses get broken if these fall down. With respect to children, a study says that 3 out of 4 children with glasses do not practise sport or do not play because they are afraid of breaking them and they would like to use contact lenses.

4.Can contact lenses slip behind the eyes and stick to these?

Both believes are false. Contact lenses can not slip behind the eye in any circumstance because this is physically impossible. And even though the eye can dry up, a correct usage of artificial tears will avoid any problem.

5. Are all contact lenses expensive?

In the same way that a variety of contact lenses exists to treat different visual problems, there are contact lenses that fit all budgets.

There are many advantages of having a clear vision without wearing any type of lense, especially in summer time. While being in the swimming pool or in the beach, where we are exposed to water and sand that can go into our eyes, the fact of wearing no type of lense decreases the probabilities of irritation and annoyance. Inconveniences are also avoided due to movement or sweat while practising sport or , for example, when we put on the motorbike’s helmet.

The Refractive Corneal Therapy is the best therapy to slow down the myopia in an important way. Many patients that use these contact lenses notice significative changes in the first days of treatment, correcting the myopia completely in one or two weeks maximum.

In fact, these are an excellent alternative to surgery, especially in occasions where it is ill-advised, in addition, in those cases implying children and young people with evolutionary myopia.

3. A treatment approved by the FDA (Food and Drug Administration) and the CE (European Commission):

Which is the appropriate age for chidren to wear contact lenses?

This question, which is frequently asked by many parents is easy to answer: at any age. Nowadays it is possible to manufacture any graduation with cornea bio-compatible materials. In fact, it exists contact lenses that correct the myopia during the night (Ortho-K): For this reason, age does not mean a problem. The decision to put on contact lenses to our children, whenever they need them, is a matter of motivation.

General and specifici motivations must be taken into account. The general one is that children, during childhood, develop their space orientation from the visual sense. It is important to detect any anomaly and correct it with glasses or contact lenses. But contact lenses fit better to their activities, since they do not need to take these out in order to, for example, play sport. With their usage, we avoid the fact that their space orientation gets affected.

As specific motivations, we analyze the advantages according to the optometrist diagnosis:

Which advantages do contact lenses have for children with respect to glasses?

  • Children with high graduation: the image children perceive in their brain through glasses does not have a real size.
  • Contact lenses avoid this sensation allowing them to see an image according to the world that surrounds them.
  • Those who suffer from hyperopia: those children often see over their glasses because at a far distance they can see properly. With contact lenses this attitude would be avoided. This attitude turns out to be a habit lots of times and this can lead to following problems because of doing a bad graduation usage.
  • In the case of children who suffer from myopia: to use contact lenses avoids the visual area restriction which happens when they wear glasses. Even though the restriction is minimum, contact lenses allow the area to enlarge.

The 5 advices to come back to school that no list includes


The vast majority of advices lists to face coming back to school with success do not include the visual health between the most important things to take into account. But this means the key to fight the school failure, since the 80% of the information explained at class enters through the eyes. Do you want to know all the advices in order to take care of your children vision when coming back to school this year?


1. Less video games, tablets and mobile phones and more homework

During the summer holidays, some children have spent a lot of hours every day in front of electronic devices. Experts recommend that, once the course has started, parents should agree with them a restricted usage of these devices and also to give more importance to homework. Screens as well as books must be situated 35-40cms. distance from the eyes.


2. To establish a good space to study

Any part of home does not mean the best place to study. Parents must provide their children with an appropriate and fixed place, with comfortable chair and table and an adequate temperature. In order to take care of their vision, the room must have natural light, whenever it is possible. The artificial light will be used with the main purpose to avoid shadows. The lack of light can lead to visual fatigue, that is why the chosen room to study should have a lamp that gives off natural light as well as an adjustable table-lamp.


3. Vision needs to rest while studying

It is suggested to rest the vision from the books or screens every 20 minutes. To have a rest does  not mean that children have to stop studying, but simply by doing the following exercise: to raise the sight and look at some far-off object during some seconds before concentrating again to look at the near material they are working with.


4. Does your child turn his/her head when reading or writing?

This is one of the signs that can tell you that your child suffers a visual problem. Also: to blink constantly, to approach too much to books while reading, to half-close the eyes, the readness of these or the rejection to reading.

In some cases, these visual problems will be corrected by means of glasses or contact lenses, but if the problem is of vision accommodation, of eyes coordination or of perception of the environment, among others, it is the Visual Therapy that can solve the problem. This therapy consists of various customized exercises that reeducate the sight of children bettering and correcting the visual and perceptual skills.


5. The annual revision, in september

To visit the optician-optometrist in order to check the children vision, must be done, at least, once a year. If you have noticed some of the symptoms mentioned above, september is the best moment to carry out the revision. The school learning is directly linked to the vision and hence when a visual problem appears, children are not able to develop their highest potential.
