Tips and Advice


How to maintain your glasses, the dos and don'ts.

What to do 

What not to do

Use running water, the provided wipe.

Using toothpaste, saliva, rubbing alcohol, or liquid cleaner for glasses. (That last one may be used punctually when very dirty, if it doesn't contain alcohol)

Keep them in their case when you are not using them. If you don't have one, place them safely with the lenses facing upwards.

Wiping them with a sweater, T-shirt, blouse, tie, handkerchief, dirty cloth, etc.

Use a clean wipe.

Exposing them to heat (Max temperature 35°C), leaving them in the car in the sun, sauna, blowdryer in direct exposure for too long.

Regularly check the condition of the lenses.

Exposing them to cold. (Min. temperature -10°C)

 

Washing the wipe above 40°C or with fabric softener.

 

Using liquid soap of any kind.

 

Using some glasses-cleaning liquids that are abrasive for lenses with anti-reflection coating.

If the arms are too loose or tight and you have an acetate (plastic) frame, you can heat them with a blow dryer (careful of not heating the lenses) for about 20 seconds, which will allow you to bend the arms in the desired angle.

How to choose a frame that will suit me?

  • Oval face : Rectangular, Oval, Square, Round, Wayfarer and Butterfly frames. No narrow frames.
  • Square face : Oval Mounts, Rounds, Wayfarer. Preferably Invisible and semi-circular rather than angular frames.
  • Round face : Rectangular, Square, Wayfarer frames. The angular frames work particularly well, rimmed and half rimmed. Avoid small glasses.
  • Heart shaped face : Rectangular, Oval, Wayfarer frames. Avoid thick frames, too large or with too heavy prints. Invisible frames soften and balance the lines of the face.
  • Face in the shape of a diamond : Rectangular, Oval and Butterfly shaped frames or invisible with a well-defined top line

How to choose lenses that will fit me?

Corrections

single-vision, progressive or degressive, which one to choose?

The choice of lenses is determined by the needs of your eyes and your lifestyle.

Most people need single vision lenses, but for those who have reached the age of presbyopia, the choice may be a little more complicated.

First check your prescription to find out what will benefit you the most.

  • Single vision lenses : suitable for those who do not have presbyopia and also for those who, having presbyopia, do not succeed in adapting to progressive lenses or need a pair of glasses for a specific distance. (reading, screen,...)
  • Progressive lenses : Suitable for those who need to integrate the different distances (near, mid and far) into the same pair of glasses. To reduce adaptation problems we advise you to choose frames with minimum 30-34mm high lenses.
  • Degressive lenses : Suitable for presbyopes in a working environment, from 30cm to 1m50.

Thinning Indexes

The choice of thinning is delicate, since it depends not only on the corrections but also on the type of frame chosen, the dimensions and shape of the lenses, and even the pupillary distance.

The result, therefore, can be very different for the same person.

However, we can give you a few tips to make your choice more successful.

  1. Consider SPH and CYL without signs: for -3.25, +1.25 x 90º it would be 3.25 and 1.25
  2. Add SPH + CYL without taking into account the signs (3.25 + 1.25 = 4.50). We will refer to this total for the choice. This is not quite the way to calculate but it gives you a more accurate idea of your needs.
  3. Check the recommended index for this total value
  • Index 1.50 : Up to 50% lighter than mineral lenses, they are suitable with a spherical correction (indicated by SPH on your prescription) of +/- 2.00 and less or with a cylindrical correction (indicated CYL on your prescription) of +/- 1.50 and less. If you need both SPH and CYL corrections, the total should not exceed 2.50 diopters.
  • Index 1.60 : more resistant and up to 20% thinner than index 1.5 lenses, they are particularly suitable for spherical corrections between +/- 2.25 and +/- 3.75 or cylindrical corrections between +/- 1.75 and +/- 2.75. If you need both SPH and CYL corrections, the total should not exceed 4.50 diopters.
  • Index 1.67 : up to 30% thinner than index 1.5 lenses, they are particularly suitable for spherical corrections between +/- 4.00 and +/- 6.00 or cylindrical corrections between +/- 3.00 and +/- 4.00. If you need both SPH and CYL corrections, the total should not exceed 6.50 diopters.
  • Index 1.74 : up to 40% thinner than index 1.5 lenses. Our thinnest lenses are designed for the most powerful prescriptions. These extremely thin lenses are suitable for spherical corrections from +/- 6.25 to +/- 10.00 or cylindrical corrections between +/- 4.25 and +/- 6.00.If you need both SPH and CYL corrections, the total would be from 6.50 diopters.

Some additional information is appropriate

If the lenses are very small (therefore height under 28mm and width under 50mm) it is often possible to have still quite esthetic and light lenses with a lower index than recommended, for "normal" size frames (therefore height 29-34mm and 50-52mm width). For large lenses (therefore height over 34mm and width over 53mm), it will probably be better for you to choose thinner lenses or possibly change the model because the result may not satisfy you.
