What is Myopia (near-sightedness), Hypermetropia (far-sightedness), Astigmatism, Presbyopia?
Myopia and Hypermetropia are optical disorders mainly affecting long distance vision. Myopia, or near-sightedness or short-sightedness, simply means that the image is formed in front of the retina instead of on the retina, therefore the person has a blurred vision without the help of corrective glasses.
Hypermetropia, or far-sightedness, is the opposite of the Myopia. The image which should be formed on the retina without any effort is now formed in the back of the retina. The hypermetropic person can put back the image on the retina at the expense of a great fatigue and even headaches, especially when she or he reads or works on a computer for a long period of time.
Astigmatism is a defect of the cornea. In this case, the eye is not perfectly round, but rather has the form of a football, and needs a corrective action on the retina.
Presbyopia is a normal consequence of ageing process of the eye. Starting from 40 years old, as crystalline lens elasticity diminishes, we start having difficulties reading small letters. We then need to wear progressive lenses that take into account all the levels of our vision (from far, intermediary and from close).
Can I wear contact lenses even If I am presbyopic?
Sure! There is a large variety of products exists today as an alternative to wearing glasses. There is no reason why you should not use these products. Make an appointment with our opticians right now.
What is a polarized lens?
A basic solar lens must protect against harmful sun rays. When we say “polarized” lens, it means that on top of the basic protection, you’ll enjoy an additional filter that cuts off a major part of the reflections coming from non metallic surfaces such as water and snow. A thin polarized film, laminated between two thin stripes of lens, will give you a double protection.
How much time should I wait to get used to my new glasses?
This might vary a lot from one person to another. For some people, the comfort is immediate, and for some others, it will take longer time. Actually, it depends on your personal capability to adapt yourself to something new and also on the changes in your prescription. A good adjustment of your frame is also essential to assure a maximum comfort. It is recommended to verify the alignment of your lenses by an optician before you start worrying. After the normal period of adaptation, several measures might be taken to make sure you regain optimal visual comfort.
Can I go to bed wearing my contact lenses?
We never automatically recommend going to bed wearing contact lenses because the eye must breathe and also because during the sleep, the supply of oxygen is limited. Nevertheless, some “new generation” lenses allow a greater supply of oxygen. It is therefore very important to take into consideration your habits when you choose contact lenses. Talk to our opticians and get informed.
What should I consider when choosing glasses?
There are as many models of glasses as there are types of faces. Several factors have to be considered: the size, the length of the temples, nose pad support, the style and the color. It’s all a matter of details. At Antoine Laoun, we are proud to offer you a vast selection of exclusive frames and also our unique know-how to help you in your choice.

Why should we throw away our contact lenses when they are still comfortable?
It is important to respect the prescribed lifespan of the lenses. This assure you a high security and decreases risks of ocular infection. The accumulated sediment of proteins, dust and bacteria might create irritation after wearing contact lenses for a long period ot time. Do not wait until you feel discomfort to take them off, this could be too late for the preservation of your ocular health.
What is the best way to clean my glasses?
First, the cleaner sold in our store is the best product for cleaning your glasses. Or, you can use a drop of mild liquid soap and cold water rubbing lenses delicately with your fingers, then rinse with cool water. You must avoid heavy duty glass cleaner products. To dry your lenses, wipe them gently with a soft cotton cloth, and then the job is done.
