In addition to protecting your eyes from debris, the lenses will adapt to the light conditions along the way. When the lenses are exposed to the sun, they adjust proportionally to the amount of light. For example, on a bright but cloudy day, the lenses may only darken halfway through. So you can wear the same pair of glasses day and night for optimal vision. They are also available without a prescription if your vision does not need to be corrected.

Transitions lenses are available in grey, brown or green.

Yes, the glasses, but especially the treatments on their lenses are ultra sensitive to temperature changes.

Who has never experienced when opening the oven door or lifting the lid of a pot of boiling water, that fog on their glasses lenses?

The repetition of these thermal shocks permanently alters the anti-reflective treatments.

 

Tips:

• Avoid leaving your glasses in the glove compartment of your vehicle.
• Remove your glasses before opening the oven door.
• Wash your glasses in lukewarm water instead of hot water.

 

               

Almost 80% of school learning involves the integration of visual information. Vision therefore plays a very important role in school success. It goes without saying that this aspect of health should not be neglected. Yet, in Quebec, only 33% of children are examined by an optometrist before they enter school. It is strongly recommended that children have an eye exam every year starting at age 5.

– We have a wide variety of affordable children’s eyewear –

 

Eye exams are available in our 14 branches with appointment booking.

They are covered by the Régie de l’assurance maladie for those under 18 and over 65 years of age.

The most common visual problems are: difficulty seeing far away, dry eyes and intolerance to contact lenses. If you didn’t wear glasses before you became pregnant, there is no need to run to your optometrist, as the situation is often temporary. Usually everything goes back to normal 5 to 6 weeks after delivery. This is why it is recommended that you make an appointment for an eye exam 2 months after the baby is born. This will allow us to determine whether your nearsightedness, for example, has worsened slightly or not.

Although it is normal to experience vision discomfort during pregnancy, there are some situations that may be a sign of more severe disease. Hypertension may be present when vision becomes blurred or if the pregnant woman sees black spots, for example. You should also consult a professional if your vision becomes double, blurred or if it weakens for more than 2 hours.

Rest assured, most situations are not worrisome and everything will return to normal some time after delivery.

The origin of the brand dates back to 1853, when opticians Bausch and Lomb set up a research company to create sunglasses. However, the Ray Ban brand was born with the well-known aviator model designed at the base for the US Air Force in 1937. Its name is in fact the contraction of Ray-Banner (banishing the sun’s rays).
Aviator sunglasses were one of their first models and one of their most popular to date. Its popularity increased in the 1980s thanks to Michael Jackson, but the brand’s reputation weakened in the 1990s due to a decline in quality, it would seem. It was in 1999, when Luxottica acquired it, that Ray Ban made a strong comeback.

182 years ago in Lyon, Ferdinand Monoyer was born, the inventor of the Monoyer scale, which is still universally used to measure visual acuity. You can even read his surname, first name and title in the form of an acrostic.

It was also Mr. Monoyer who, in 1872, proposed the use of diopters to measure the power of lenses. This unit makes it possible to calculate the degree of correction of lenses used for myopia or hyperopia. The higher the diopter, the greater the correction. To correct myopia, the diopter is negative. To correct hyperopia, the diopter is positive.

Predators have vertical pupils to enable them to accurately estimate the distance to their prey. In addition, they improve depth vision to better focus on the animal. Prey have horizontally shaped pupils to help them protect themselves. The horizontal shape of their pupils gives them a panoramic view to allow them to better perceive the threat that may approach them and to assess the irregularities of the terrain in order to save themselves.

As soon as your lenses come into contact with the air, the calculation of their lifetime begins. The number of times you’ve worn them is not an indicator of when to throw them away. It is important to have a proper lens care routine to avoid eye irritation. When you open a new box of lenses, write the date on the individual package; this will make it easier for you to know when to renew with your optician.

Presbyopia is a normal aging process of the eye that usually appears around the age of 40. The crystalline lens loses its elasticity and makes it difficult to focus for close reading. Glasses are used to correct a visual disorder. Wearing them is a matter of comfort, but also a way to avoid visual fatigue or headaches. Not wearing glasses to work on your eyes will not improve your vision.

When a picture is taken in a dark place, the flash is so fast that our dilated pupil does not have time to shrink in this strong light.
The camera’s flash therefore reflects in the back of our eye, letting us see a red colour due to the large number of blood vessels in the eye. For a few years now, cameras have been sending a mini-flash before taking the picture, so that our pupils have time to retract to avoid this phenomenon.
