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.

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.

Last November 11th we attended the 8th edition of the Contactology Forum organized by the Facultad de Óptica y Optometría de Terrassa. The event was sponsored by 15 laboratories dedicated to contact lenses and maintenance products.

During the journey different conferences are organized with subjects related to present time and of interest  about the optician’s and optometry’s world. The main objective of this meeting is to pick up the different opinions of the professional people that attend, in order to be able to speak deeply about the different subjects.

In this edition the subjects explained were:

. The last advances and treatment for the dry eye.

. Multi-focal contact lenses’ adaptation.

. The importance of the social network in our cabinet.

Continually, laboratories are investigating in order to achieve a better vision with the usage of contact lenses. In this case, we have focused on finding solutions for the users that have a double problem such  as presbyopia and dry eye.

Starting from 40 years, lots of people decide to give up the usage of contact lenses for these reasons, that is why it is very important to be updated with the last advances regarding artificial tears and the materials the contact lenses are made of.

By means of these studies we try to find out the better results so that our patients can benefit from this.
