We contradict 5 false myths about contact lenses

OLYMPUS DIGITAL CAMERA

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.

The 5 things you must know about the ortho-k contact lenses

TERAPIA_CORNEAL_REFRACTIVA_LENTS_ORTOK_BIOPTIC

Do you have myopia and to wear glasses or contact lenses does bother you? Do you want an alternative to surgery? The Ortho-k contact lenses are contact lenses that you can wear while you sleep in order to forget about glasses during the day. By means of the Refractive Corneal Theraphy (CRT), these contact lenses modify the corneal curve correcting the myopia – as well as astigmatism and hyperopia – in order to enjoy a clear vision during the journey.

1. Why do you forget about glasses and contact lenses during the day?

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.

2. The best procedure to slow down the myopia significantly:

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):

Since this is a treatment that many people do not know, they think this is a new treatment. The truth is that since many years ago, hundreds of patients use the Refractive Corneal Therapy, which is applied by means of the Ortho-k contact lense, the first and only contact lense authorized by the FDA, American Health Organization similar to the Spanish Health Ministry and the European Commission.

4. Ortho-K, contact lenses for all ages:

Especially recommended for young people, these contact lenses are adequate for any age.

 5.  Until how many dioptries can these contact lenses correct ?

The Ortho-k contact lenses correct until 6.00 graduation in myopia, until 1,75 in astigmatism and until 3.00 in hyperopia.

5 things you must know in order to see the sun eclipse

Consells per veure eclipsi solar

The fact that the moon crosses ths sun’s path creating an eclipse does not happen every day. In fact, the eclipse that will take place on Friday 20th March did not happen, in the same magnitude, since 1999. Some countries such a Denmark or some locations at the United Kingdom will see more than the 80% of a covered sun. Here we will also be able to see it clearly starting from 9:16am, according to the information given by the National Astronomy Observatory.

This same institution also gives us some advices in order to look at this astronomical marvel in a secure way.

How not to do it:

  • Do not look at the sun directly or with sunglasses. Since the sun is not completely covered by the moon, it keeps on annoying the eyes when we look at it fixedly and it can damage our eyes.
  • Do not  look at the sun with devices or instruments that are not specially adapted. The cameras of any type, binoculars or telescopes without the appropriate sun filtres are not recommended, either, to observe the eclipse. It must also be taken into account the homologation of the filtres that will be used.
  • Optic instruments are not recommended at all. The observatory does not recommend the optic filtres that are added to the eye, since these can overheat and break.

How to do it:

  • To project the sun image on some screen projected to a shadow. One of the ways to observe this phenomenon is projecting it on an even surface. Do not look to what it shows you, but look at the reflex that it makes.
  • To use “eclipse sunglasses”. With these filtres with a glass shape, one can look at the eclipsed sun without problems. But the glasses must be standardized by the European Community and must be used following the precise instructions. These must be used preferably while being seated and must not be taken out until one gives up looking at the sun and must not be combined with other optic devices.

Now you know how to enjoy the sun eclipse with maximum security guarantees for your sight. You can share this article if you find it interesting.

Terapia Visual para mejorar aprendizaje de tus hijos

Re-educate your children vision with visual therapy

Our children visual abilities are developed in a similar way as when we learn to speak or to walk. That is, we must also learn to see in order to be able to interpret and understand the world. In fact, the 80% of the information that children receive at class is through the eyes, but to have a 100% visual sharpness does not guarantee a good vision. The definition of good vision does not only mean to have physically healthy eyes, but also to be able to identify what we are seeing, process and understand it. For this reason, glasses or contact lenses are not the solution if the problem has to do with visual accommodation, coordination between the eyes or perception of the surroundings, among others. In this point, the visual therapy allows us to solve the problem.

What does visual therapy mean?   

The visual therapy or training is composed of specific exercises customized in order to re-educate vision and make it more efficient. This is achieved correcting and improving the functional and perceptual abilities (link: https://bioptic.net/en/visual-therapy )The exercises evolve and vary in difficulty as the therapy goes on and adapts to the problems and objectives of each child.

How does it help our children?

Starting from these exercises children establish new connections or nerve cell schemes that will help them to process correctly the visual information. All the things learned with this therapy can be applied to their daily life, developing a strong visual system without any effort. Just in this way they will be able to concentrate on the purpose and not on the way: to learn instead of being observant if they see in a proper way or not.

How can we detect that children need visual therapy?

If you detect more than two of the following behaviours in your children, it is recommended to consult an optometrist:

– Reads very slowly,

– Does not understand what he/she is reading,

  • Uses the finger while reading,
  • Transposes letters and/or numbers when reading and/or writing,

Confuses right and left,

Skips words and/or lines while reading,

Has inadequate postures when reading or writing,

Complains of blur vision,

Gets very close to the paper while reading and

Half-closes the eyes when looks at far distance.

When did you last review your children vision?

The election this summer: polarized glasses? 

consells_ulleres_sol_bioptic_salut_visual

Despite the fact that polarized glasses exist since many years ago, these glasses are considered as fashion since three years ago. But, if the sales of this sunglasses style keep going during so many years is not only because these are fashion, but because of their usefulness.

When we put on sunglasses, the pupil gets dilated. This means that without an adequate protection against ultraviolet rays (UV), the sun can affect more negatively on our eyes and can even lead to lesions. In this sense, the polarized glasses can also offer a UV protection of the 100%.

Which other advantages do they have?

  • These fight light from all angles: the sun light reaches our eyes from all possible directions. In fact, there are typical situations in summer time that multiply the angles where the light comes from: the reflection of the sea water, swimming pools and asphalt. The polarized glasses have a special filtre that avoids all reflections coming from horizontal surfaces.
  • Vision without reflections that improves the visibility.
  • The clarity and contrast of what we see is superior.
  • These glasses are adequate for people with high sensibility to light and also for children.
  • As any other lens, this diminishes the eye fatigue.
  • These glasses can be prescription glasses.
  • Needs to be mentioned the fact that, as disadvantage, in some cases the polarized glasses diminish the visibility of cell phones screens, GPS or other devices. Despite this, these are the most recommended, even more for those who spend lots of hours under the sun light and are exposed to situations where the light reflection multiplies, such as, for example, people fond of navigation, beach or those who drive during many hours.

The 5 advices to choose appropriate sunglasses

consells_ulleres_sol_bioptic_salut_visual

Do you know that the sun overexposure can cause eye problems such as photokeratitis (corneal injury) or favour the development of cataracts or macular degeneration? The election of appropriate sunglasses is not only a  matter of fashion, but a matter of visual health. Biòptic provides you with 5 advices in order to get right with your choice:

1. UV protection glasses:

It is essential to check the UV, ultraviolet rays abbreviation, grade. The need of more or less protection will depend on the glasses usage. During the summer, it is necessary a protection grade between 81% and 92% of absorption, which is adequate for a medium and high sun brightness.

Glasses must be used at all hours, since the UV rays, even though they are imperceptible, these are also present when cloudy days. Generally this information is indicated on the glass sticker.

2. Which type of glass must be chosen?

Polarized: this is the glass that protects the most par excellence. All the residual reflections are avoided with the polarized filtre.

Sunsitive: these glasses are used by sportsmen that play activities where they move from direct light to shadow; the glass varies its tone depending on the quantity of light.

Degraded: the most chosen glasses because of aesthetics reasons; the tone of these glasses is more clear gradually. That is, the upper part is darker and the lower part is more clear. These are adequate to wear indoor and when it is not very sunny.

Uniform: the colour of the glass is uniform and this is the most usual way we find sunglasses.

3. A frame that protects the eyes from all angles:

–The large variety of frames makes us choose the best one according to our face shape in order not to leave any crack where the sun can get into and also that these suit us:

–Heart shape face (wide forehead and pronounced chin): the aviator style of glasses is recommended.

–Square face (wide forehead and jaw): the glasses that are recommended in order not to give too much protagonism to the forehead are the oval glasses or those that do not have the upper line straight.

Round face (wide forehead and voluminous cheeks): one must not choose round shapes and select rectangular ones, which are glasses that are wide in the upper part and narrow in the inferior one.

4. Children, the most vulnerable to sun:

Do you know that it is not until the age of 12 that the crystalline is completely formed and the retina is not yet protected? In the same way that we protect children’s skin from the sun, we must also protect their eyes. Special care must be taken into account when protecting their vision.

5. Optician’s as quality filtres:

The best way to choose sunglasses is consulting experts. That is why going to the optician’s to find the sunglasses for this summer means a secure purchase. Listen to experts’ advice.

Ortho-k contact lenses, your allied contact lenses this summer for 3 reasons

Vision Aid - Contact Lens

The beach sand can easily get into your eyes, which can make the conventional contact lenses, those used during the day, leap. To suffer a blow in the swimming pool or a bycicle fall can also lead to the traditional contact lenses loss, which can even get broken. These are only three examples from a big list of summer holidays moments that prove that wearing glasses or conventional contact lenses is not always the most comfortable option. Can you imagine a type of contact lenses that one uses during the night and which allow one to have a clear vision during the day without wearing anything in the eye? The ortho-k contact lenses will turn out to be your best allied contact lenses during summer time for these main reasons: security, comfort and health.

 

  • The most secure option

Since these contact lenses are nocturnal, the vision is clear during the day without wearing any type of contact lense in the eye. This is possible because the Ortho-k contact lenses apply the Refractive Corneal Therapy (CRT), which modifies the corneal curve correcting the myopia. This is the most secure option, since it is impossible to harm our eyes, because we do not wear any contact lense. This is an absolutely secure treatment, since it has been approved by the United States FDA, which is the american health organization and also from the European Community.

 

  • The comfort of wearing no contact lenses

The fact of wearing neither contact lenses nor glasses, because the Ortho-k contact lenses correct the myopia during the night, makes the probability of irritation and inconveniences typical of the conventional contact lenses decrease. In a period where the sport, beach or swimming pool activities are more appropriate, the fact of wearing neither contact lenses nor glasses is a pleasure. Despite this, one must  not forget about the sunglasses, especially in the case of children.

 

  • A matter of health: to slow down the myopia

The therapy applied by means of the Ortho-k contact lenses, the Refractive Corneal Therapy, is the best one to slow down the myopia with significant results. These contact lenses become the unique choice to surgery, ill-advised in the case of children and young people with evolutionary myopia and in other particular cases.

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

vuelta_al_cole_salud_visual_bioptic

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.
