How to find the right contact lenses?
The market for contact lenses is as diverse as their users. For each eye shape and each visual defect, there are perfect contact lenses: toric, progressive and spherical, hard or flexible…. There are several factors to consider when purchasing contact lenses, so it can sometimes be confusing to know which ones are good. But if you already know the values of your eye recipe, it will be much easier for you to choose.
Spherical lenses - contact lenses for myopia and hyperopia
Depending on whether you have difficulty focusing on near or far objects, you are myopic or farsighted. People with myopic vision have a negative diopter value and see more blurred as the distance from what they see increases. Hyperopics, on the other hand, have a positive number of diopters, the more difficult it is to see closely. This visual defect is caused by eyeball shape, which is not round, but stretched or flattened in its frontal-posterior axis. Therefore, the light passing through the lens is not projected into the center of the focal point of the eye, but in front of or behind the eye.
The spherical lenses can easily correct these visual defects. Like glasses, their shape changes the optics of the eyeball so that the focal plane returns to the correct position and can be seen clearly. As contact lenses are placed directly on the lens, i.e. much closer to the eye than glasses, the dioptric values of these two types of lenses are different.
Toric lenses for astigmatism correction
People withastigmatism see distorted objects. It's because the cornea is not cylindrical but elliptical, so that refraction is not produced exactly for correct vision. The toric lenses compensate for these limitations. These lenses form a cushion of tear fluid above the eye, recreating the cylindrical shape for correct vision. Toric contact lenses should be adjusted by a doctor or eye care professional because they must be correctly positioned to prevent eye damage. In their commercial packaging, they are recognized by including the term "toricas" or "for astigmatism". Toric contact lenses are available in all common dioptric values for people with myopia or myopia.
Progressive contact lenses, variable correction from near and far
The human eye is designed to see from afar in a state of relaxation. When focusing on close objects, the eye muscles contract and deform the lens to allow clear vision even in close proximity. With age, theelasticity of the lens decreases gradually. While young children can compensate up to +3 diopters without glasses, adults over 40 have trouble seeing closely, even if they don't have nearsightedness at first.
This form of presbyopia associated with age is called presbyopia. If you are short-sighted and with age you add presbyopia, you will need corrective lenses for different areas of sharpness that will allow you to see both near and far. The progressive or multifocal lenses are the contact version of progressive lenses. They are easily recognizable because their commercial labeling includes the terms "progressive", "multifocal" or "for presbyopia".
Duration of use: a fundamental criterion
You can select with a single click the different types of lenses according to their duration of use. Those that already exist are:
- Daily replacement contact lenses
- Weekly contact lenses
- Monthly contact lenses
Daily replacement contact lenses: hygienic disposable contact lenses
If you are a passionate spectacle wearer who only uses contact lensesoccasionally, daily contact lenses are your ideal choice. They are placed on the eye in the morning, and in the evening, before going to bed, they are removed and discarded. These practical contact lenses incorporate terms such as "Dailies", "Daily" or "1 Day" in their trade names.
No other cleaning product is required for daily wear disposable lenses. You can remove them - always with clean hands - directly from the sterile container and put them on. If you ever need to clean your contact lenses, it is a good idea to have a small bottle of contact lens solution on hand.
Weekly contact lenses - the alternative to daily contact lenses
If you regularly wear contact lenses in addition to your glasses, weekly lenses may be your ideal choice. These lenses can be worn for 14 days from the moment you take them out of the container. At the end of the day, they are rinsed with a cleaning solution and we let them disinfect overnight. For the people with sensitive eyes or high hygiene requirements, weekly disposable lenses correspond to the average of daily and monthly contact lenses. However, the range of weekly lenses available is less than that of daily or monthly lenses.
Monthly lenses, for anyone who wears lenses on a regular basis
Monthly lenses can be worn for 30 days from the moment the container is opened. As with weekly contact lenses, it is very important to maintain them well. Its correct maintenance will depend on the products used. Various storage and maintenance solutions are generally used for monthly lenses. Consult an optician to find out the composition and use of each product according to your needs and prevent possible allergic reactions. Your optician will also give you valuable advice on the optimal maintenance of your monthly lenses.
Special contact lenses for dry eyes
Just because someone has them dry eyes that she has to give up her contact lenses. The silicone hydrogel lenses prevent excessive loss of tear fluid and help partially hydrate the eye. These lenses are made of a material that absorbs water very quickly and releases it very slowly. Thanks to these "water tanks", contact lenses have a better water supply and do not absorb as much tear fluid. In comparison, they require 20 % less water than hydrogel contact lenses because they draw less fluid from the eye.
If your contact lenses dry your eyes, it may be because you did not choose the right product or because you did not take care of it. Hormonal changes can also cause dry eyes, so contact lenses that used to be comfortable to wear are suddenly boring. Remember to always ask advice to your optician or ophthalmologist for the choice of your contact lenses.
Contact lens adjustment: advice from your optician or ophthalmologist
If you wear contact lenses for first time, consult your optician or ophthalmologist for advice. It will help you adjust your lenses, that is, choose the ones that suit you best according to your needs. Bad lenses can irritate your eyes and even cause serious eye damage. If you want to wear "hard" contact lenses with a stable shape, a precise adjustment by a professional is essential. Even experienced contact lens wearers should be examined once a year by an optician or ophthalmologist to see if their vision has changed.
