Which contact lens solution is better and how can I replace the solution

Contact lenses - This is a convenient and comfortable means of vision correction, a real salvation for those who for many years wore glasses and were tired of them. They are especially convenient for people with a high degree of myopia, who were previously forced to wear glasses with thick glasses. The only difficulty in using lenses is the care of them: it is necessary to rinse them every night with a special solution and place them in a container, which is also regularly washed, or replaced with a new one.

The solution performs several important functions: it disinfects, cleans and removes impurities and maintains it in a suitable condition - it moisturizes and softens. There is a wide selection of solutions, all of them have their own advantages and vary slightly in composition and quality.

Which contact lens solution is best

  • Avizor Enzyme Tablets - contain the microbiological enzyme subtilisin, due to which protein deposits are most effectively broken down and removed. For all its strength, this component is not toxic and does not cause eye irritation. Used once a week. The tablet is placed in a container filled with a multifunctional solution, after complete dissolution, the lenses are placed there and left for a time from 30 minutes to several hours. Then they must be washed well. The feeling of using the solution is as if the lenses had just been acquired, a pleasant discovery by the lens owners with a long wearing period, a month or more.

Types of solutions for lenses

  • Multifunctional - perform several functions at once: they disinfect, clean and moisturize. Almost not felt by the eye, as they have a softening effect, universal.
  • Water and salt - are intended for storage and washing, perfectly preserve lenses, repeat the composition of an ordinary tear. They have appeared on the market since the release of the very first contact lenses.
  • Daily - well cleaned, but unsuitable for storing lenses in them. Peroxide - due to the content of a 3% hydrogen peroxide solution, they are more efficiently cleaned. However, after its use, washing is necessary, since the peroxide solution itself can cause burns to the mucosa. It is used 2 times a month, not more often, for long-wearing lenses. Enzyme - eliminate protein pollution. In such a solution, you need to lower the lenses for 15 minutes, then rinse and put in a container. You can add it to a cleaning or water-salt solution. Recommended use once every 7 days. Available in the form of enzyme tablets that need to be dissolved.

Important: According to experts, the more moisture, the less antiseptic properties the solution has, the greater the risk of infection, therefore, using solutions with hylauronic acid, you must additionally monitor hygiene.

How can I replace the contact lens solution?

How to replace a solution for contact lenses if you find yourself in an unusual situation, for example, are forced to spend the night out at home, but there is no solution with you? There are solutions to this issue:

  • Saline solution. Cheap and affordable, sold at the pharmacy. Before use, it is necessary to disinfect the container into which it will be poured. Of course, saline does not disinfect the lenses, but will help maintain their shape and flexibility.
  • Distilled water. At least boiled, in which it is necessary to add salt in a proportion of 9 grams (half a tablespoon) per 100 ml, is suitable. It is important to wait until the salt has completely dissolved before putting the lenses in there.
  • Moisturizing eye drops. As a rule, they are sterile, which means they can disinfect lenses. The composition of many moisturizers also includes hyaluronic acid, which means that lenses after night will not cause discomfort in this liquid. The bubble with drops is small, and you can always have it at hand, including for such unforeseen cases.

Nevertheless, such tricks are designed for an extreme case and are not a complete replacement for a cleaning solution for lenses. As soon as it becomes available, it is necessary to remove the lenses from the eyes and put in a solution for disinfection, and if necessary, use additional cleaning agents. It is impossible to predict in advance what effects alternative lenses will have on lens condition, so it is better to avoid such situations and use only proven contact lens care products.

Contact Lens Composition

The composition of the liquid for contact lenses includes many components, but the two main factors affecting its function are salt composition, or osmotic pressure, and acidity (pH).

Important: The chemical composition should approach tear fluid, without this the lens will swell in water, absorbing it into itself, that is, it will lose its consumer qualities. Solution should be isotonic, this is the equivalent of a 9% solution of ordinary salt, and have a pH of about 7.4.

The second component of the solution is surface-active substances (surfactants)or surfactants that are a detergent. They clean the lenses of the components of the tear fluid in the eye. The higher their content, the more efficient is the purification of protein, lipid and colloidal deposits.

The third component is preservatives., or disinfectants. They do not allow microorganisms to multiply and reduce their concentration. The most commonly used for this are lawless chloride (BAC), polyquad, dymed, chlorhexidine, analogs of hydrogen peroxide - berborates.

And the last component of the solution is air conditioning, which moisturizes and lubricates the surface of the eye, making staying in the lenses more comfortable. The function of the humidifier is usually performed by hyaluronic acid.
