Contact lenses have taken center stage in the day to day of many people who have incorporated them into their routine to replace prescription glasses, thus achieving more freedom to practice physical activities or to see with higher quality without the frame of the prescription glasses hindering vision, among many other advantages of wearing contact lenses.

However, before you start wearing contact lenses you should know all the types of contact lenses that exist in order to decide which one best suits what you need. Therefore, if you are considering giving contact lenses a chance, we recommend that you continue reading this post to know first-hand all the types of contact lenses that exist and you will find in our Optics stores.

What types of contact lenses are best for me?

The first thing you should ask yourself is what you want them for and how long you are going to wear the contact lenses, because depending on your answer you must choose one or the other. It is also important that you take into account if you have dry eye or if you have sensitive eyes, since then perhaps you should moisturize your contact lenses more frequently with artificial tears to give you the comfort expected from contact lenses.

After all, the ideal would be that you let yourself be advised by a professional and, if necessary, you were trying several types of contact lenses until you find the perfect option for you. In Optics & University Audiology we have a wide range of brands that will facilitate your choice, and we also offer free contact lens test.

Types of contact lenses according to eye correction

Each refractive error requires specific contact lenses, so this will be one of the first considerations you should take into account when buying your contact lenses.

• Contact lenses for myopia and hyperopia. Spherical contact lenses are used to correct refractive errors such as myopia and hyperopia, so they have a spherical surface – curved inwards in the case of myopia and outwards in the case of hyperopia – that corrects refractive errors to provide clear vision without blurred reflections.

• Contact lenses for astigmatism. Also known as toric contact lenses, these types of contact lenses are useful for people who have astigmatism and depending on the amount of astigmatism can not focus on objects clearly.

• Multifocal or progressive contact lenses. Progressive contact lenses, or also multifocal, serve to correct myopia, hyperopia and / or astigmatism and, at the same time, presbyopia (eyestrain). That is, it helps provide sharp vision both near and far.

• Colored contact lenses. It may also be that the decision to wear contact lenses is not strictly related to a visual problem and has to do with aesthetic reasons. Colored contact lenses allow you to modify the color of your eyes in a very natural way without having to graduate them, although there is also the option.

Types of contact lenses according to the period of use

Are you going to change your contact lenses every day or do you prefer reusable ones? Answering this question may seem like an easy task, so at this point you should be very clear when and when you will want to wear your contact lenses. That will make you decide between disposable or reusable ones.

• Daily contact lenses. As its name indicates, daily contact lenses should be changed every day after use and discarded in the trash to, the next day, be able to release new ones. It is a highly recommended option among people who only need to wear contact lenses on time or on specific days, since they hardly require exhaustive maintenance and hygiene. Also for those users who do not want to clean the contact lenses every day.

• Biweekly contact lenses. It is one of the least popular types of contact lenses because it is an intermediate point between daily and monthly contact lenses, although they also have their advantages. They can be used continuously for a period of 15 days and require the same maintenance as the monthly ones.

• Monthly contact lenses. The monthly contact lenses are designed to give them a use of 30 days and then replace them with a new pack, so they are usually the most economical option for those people who are clear that they want to wear them every day. Unlike the daily ones, these must be cleaned and disinfected overnight with a specific contact lens liquid to be able to use them again the next day.

Types of contact lenses according to the material

Last but not least, you should choose the material from which contact lenses are made to make them as comfortable as possible, and here there are only two options: hydrogel or silicone hydrogel.

• Hydrogel contact lenses. They were the first to be introduced to the market and are made of gel-shaped plastics containing water, called hydrogels. They are characterized by the great flexibility they have and the ability to adapt to the human eye, since it is a very thin material.

• Hydrogel silicone contact lenses. Silicone hydrogel contact lenses have been an advance in the world of contact lenses, since the material of which they are composed allows more oxygen to pass to the cornea thus avoiding problems of dry eyes and irritations. By keeping the eye hydrated, it has also made it easier for this type of contact lenses to be worn for longer in a row.

Now that you know all the types of contact lenses and the possible combinations that exist, which ones are you going to choose?
