Many people write to me every day asking me what would be the most suitable prescription cool glasses for their new glasses and how to buy them at the best price. Well, it is not a trivial question since there are many types of lenses for glasses and, for those who do not know anything about optics, it is really complicated, if not impossible, to know if you are buying the glasses you need and paying the right price for your lenses.

Did you know that you can choose between Single vision, progressive or occupational lenses? A standard or custom progressive lens design? Different lens materials: mineral, organic, polycarbonate, high index? What are crystals that are better for a myopic person than for a hyperopic person with astigmatism?

Well, forget it, I wouldn’t be able to do it alone and that’s why I give my opinion and advice to everyone who writes to me. As there are probably many more people who ask themselves these questions on a daily basis, I have decided to write this modest guide (purists will forgive me), which aims to help those people without optical knowledge to understand which ophthalmic lens they should buy based on your budget and your visual defect: nearsightedness, farsightedness, astigmatism or presbyopia.

What is Optical Prescription

This is the first of all because if you do not know what visual problem you have, we will not be able to explain which prescription glasses to choose.

Now, I am not going to give you many details here. What is each value? Are the glasses for long face suitable? What is its meaning? What do they imply in terms of vision correction? If you have doubts, you read it first, and then we continue, okay?

You need to know that the price increase is not linear but exponential. This is because the difference between a single vision lens and a high-end or personalized progressive lens is very important: technology, design, multifunction, customization, etc.

Solar lenses are priced similarly to classic single-vision lenses. Except in the case of polarized or photochromic lenses, whose prices are significantly higher due to the fact that they are lenses with optical properties far superior to those of a classic sun lens.

Also, do not forget to always buy approved lenses that are sold by authorized establishments: My reasons for not buying sunglasses on the street. There are also special tints for people who suffer from visual problems and need a lens color adapted to their pathology.

Anti-reflective coatings are usually an option and their price is added to that of white lenses, although some types of high-end lenses come with them by default. 

The price of prescription eyeglass lenses can be significantly influenced by the material and refractive index in which they are made.

The increase in the price of lenses for prescription glasses is practically linear. This is because the difference between materials has been greatly reduced and the price differences are less strong than when it comes to lens types.

It is important to always think about acquiring lenses whose manufacturing material protects from ultraviolet radiation. Not all materials do. The material and refractive index may be combined with other parameters: treatments or type of lens, this combination will determine the final price of the pair of lenses.
