With the aging of the population, more and more people are affected by presbyopia . A visual disturbance , which prevents the lens of the eye from focusing properly, resulting in blurred vision and eye strain . Presbyopia is usually between 40 and 60 years of age and causes people to have difficulty reading correctly at the usual distance of 30 cm. It is to help these people to read with serenity, that were born the glasses loupes .

The graph of g is a vertical translation of the graph of the parent linear function. A right triangle with an area of 8 square units is formed by the x-axis, the y-axis, and the graph of g. Write an equation for g.

I have used the EDI platform for approximately three years and I have seen gradual improvements, especially with regard to catalogue updates. First and foremost, I like the timesavings the system provides for orders...

Better reading when you suffer from presbyopia, without investing in corrective lenses: this is what magnifying glasses allow. How do they work and above all, do you have to invest to enrich your catalog? We will explain everything to you.

Magnifying glasses are based on a very simple principle: two magnifying glasses, which magnify according to several diopters (from +0.50 to +4) and which allow to better discern the characters to read. It is therefore basic corrections. In addition, they are cheap and available without a prescription, one of the reasons for their success with people who do not want to wait to make an appointment with their ophthalmologist . On the other hand, they are not intended to correct visual disturbances , such as farsightedness, myopia, astigmatism, which are often already present at the moment when presbyopia appears.

The EDI platform has become an essential tool in my daily professional life. Sending lens orders directly to the plant is an appreciable timesaving and reduces the room for errors caused by oral orders.

For optical manufacturers, making magnifying glasses may be advisable to attract a new audience, but also new outlets: pharmacies, supermarkets or websites, which market this type of frames.

The reliability of the Eyes-Road platform for transferring orders lets us focus on value added services. The distribution of catalogues is an exemplary ability. It replaces numerous direct exchanges with opticians by a central distribution point...

If the magnifying glasses are not suitable for people with real underlying vision defects, they may be a good idea for those who have never needed to wear corrective lenses before the onset of presbyopia . This is called emmetropic people, who make up about a quarter of the population. At home, magnifying glasses are used as a troubleshooting solution and can correctly correct the view during close reading. They can also help reduce visual fatigue , caused by the accommodation difficulties of presbyopia .

A big thank you to the Eyes-Road team for their responsiveness, teaching, professionalism and good humour! In one week we went from “nothing” to a valid EDI catalogue, ready to receive electronic orders from our equipped customers...

Eyes-Road makes it possible for manufacturers and software publishers to have just one contact for everything concerning EDI flows, which continue to increase in the optics market. Furthermore, this lets us meet regularly...

The parent linear function is f(x) = x. This graph has a slope of 1 and intercept (0, 0). A vertical translation means it is shifted up or down. Notice that if this graph is shifted up or down, it forms a right triangle with the x and y axis as two sides of the triangle. The area of a right triangle is (base x height)/2. In this case, the base is on the x-axis and the height is the distance on the y-axis. Since the slope of this line is 1, we know that the base and height must be the same (change in y equals change in x).

So (base x height)/2 = 8, which means (base x height) = 16. So the base and height must equal 4. So the graph is shifted 4 units up or 4 units down. From the information given, it could be either up or down, so there are two possible answers. The equation could be g(x) = x + 4 or g(x) = x - 4.

Today I work with EDI to save time. Before I used the Internet to place my frame orders, but it took me 2 to 3 minutes per transaction. Now, it only takes me a few seconds; the steps are easier. I use EDI everyday for lenses ...

However, these benefits need to be qualified. The magnifying glasses are indeed a solution for troubleshooting and are not intended for people suffering from a real defect of vision. They can not in any case replace a visit to an ophthalmologist . In addition, their lenses are of lower quality than conventional corrective lenses and are, for the most part, devoid of protective filters (eg blue light ) and surface treatments such as antireflection . Nor do they correct optical aberrations, which can cause distortions of the image around the glass.
