Select your lenses
What should I take into account when choosing them?
If you have already had your eye exam done and have chosen the frame that best suits you, you are only one step away from having your prescription glasses. You only need to select your lenses bearing in mind your prescription and the design of your frame.
There are many options of materials, thicknesses, treatments, etc. for the prescription lenses. However, it is enough if you have two basic keys clear so you can make the best choice:
If you can answer these two questions, you will know how to select the right lenses. With the information that we leave you below, you will not have any problems.
Mineral lenses or organic lenses? What are the differences?
The first great distinction we make is the basic material. While there are mineral lenses (the actual glass), at Visual-Click, except in special cases, we will always work with organic lenses (usually polycarbonate). This is mainly due to the amount of advantages that organic lenses have over minerals:
Advantages of organic lenses:
o They are lighter than mineral lenses.
o They are more durable.
o They are more resistant to breakage and, in case of breaking, do not shatter.
o They are more resistant to the sun's rays.
o They can be dyed in any color.
Advantages of mineral lenses:
o They are more resistant to scratches.
o They are indicated for progressives.
What reduction index should I select?
The ideal reduction index depends fundamentally on your prescription. The higher it is, the thicker the lenses will be. This, in addition to being a negative point at the aesthetic level, can be a problem due to the weight that the lenses can reach. So, to avoid discomfort, the ideal is to reduce its thickness. The higher the reduction index, the finer the lenses will be. This leads to the big question: What reduction index is best for my prescription?
ORGANIC LENS - INDEX 1.5
It is the conventional index lens. It is for prescriptions up to +/- 2.50 diopters.
REDUCED ORGANIC LENS - INDEX 1.6
It is the medium index lens (thinner and lighter than conventional organic lenses). This index is used in prescriptions between +/- 2.50 and +/- 4.50 diopters.
SUPER REDUCED ORGANIC LENS - INDEX 1.67
It is the lens with very small thickness. Due to its special design, an important reduction in weight and edge thickness is obtained, thus obtaining a more aesthetic lens than conventional lenses. They are used for prescriptions from +/- 4.50 to +/- 7 diopters. At Visual-Click, all lenses with index 1.67 are aspherical, which helps to improve vision and not increase or reduce the appearance of the size of the eyes, so that they are more favorable.
SUPER REDUCED ORGANIC LENS - INDEX 1.74
It is an organic lens thinner and lighter than lenses with index 1.67. It is up to 60% thinner and lighter than conventional ones. They are used for prescriptions from +/- 7 diopters. As in the case of the 1.67 index lenses, they are aspherical to avoid aberrations and obtain a more aesthetic effect.
The reduction index is automatically selected based on your prescription parameters.
