The Opti-Free lens solution is used to moisturize, disinfect and clean all types of contact lenses. It contains sodium chloride, potassium chloride, sodium borate, sodium hydroxide and / or concentrated hydrochloric acid to neutralize pH and other components. The fluids used to clean and irrigate the lenses are isotonic solutions that repeat the composition of the internal environment of the body.
Why do I need a solution for lenses?
A person blinks hundreds of thousands of times a day. This is necessary so that the cornea does not dry out. During strong winds or when debris enters the eyes, lacrimation begins. The contact lens itself is not cleaned in any way, except that it accumulates elements harmful to the eye.
Opti-Free is a lens solution that is popular with people who wear lenses daily. Someone prefers it because of the relatively affordable price - this solution is cheaper than some analogues, like Renu Multiplus; to someone, this liquid is to its liking because of its versatility.
When prescribing contact lenses as a method of vision correction, you should carefully listen to the recommendations of your ophthalmologist. One of these tips is the regular use of a lens solution for a long wearing cycle.
Daily replacement of the solution is a necessary procedure, since during the day bacteria and microorganisms settle on the surface of the eye, which can cause discomfort and irritation.
Also, one must not forget about the physiological secretions of the eye. Since the lens is a foreign object, the body begins an active fight against it, secreting special proteins - lysozyme, immunoglobulins, albumin. These deposits displace moisture from the lens, inevitably causing it to dry out, which leads to discomfort and a feeling of "sand in the eyes."
Opti-Free: Varieties
Opti-Free is a lens solution manufactured by ALCON, an international corporation specializing in vision-correcting products. These solutions have been loved by millions over the decades of the company for its functionality, efficiency and ease of use.
Currently, there are several types of solutions: Pure moist, Express and Replenish, as well as AOSEPT PLUS solution for peroxide cleaning and eye drops designed to irrigate the surface of the cornea while using lenses.
Solution for lenses "Opti-Free Express"
This type of solution is intended for active individuals who do not have a large supply of time for long processing. The waiting period for lenses in this solution is only 6 hours, but reviews confirm that this does not affect wearing comfort - it is guaranteed to maintain the optimum moisture level in the lens for 8 hours.
Processing is no different from the standard:
- Mechanically clean the lens for 20 seconds.
- Rinse on both sides.
- Fill the container with fresh solution and put the lenses there for at least 6 hours.
This simple ritual will help remove all protein and fat deposits, as well as disinfect.
Opti-Free Replenish Lens Liquid
TearGlyde's unique technology keeps moisture in the lens for up to fourteen hours. This is six hours longer than most other solutions. This technology allows you to spend all day in contact lenses. At the same time, consumers note that they do not experience any unpleasant sensations, including no redness of the eyes at the end of the day.
This solution is recommended by many ophthalmologists around the world, including the United States - the birthplace of this manufacturer.
Opti-Free Pure moist lens solution
This type of fluid will help extend your comfortable wearing time up to 16 hours due to the HydraGlyde patented moisturizing matrix. This technology makes it possible to evenly distribute moisture on the surface of the lens, which allows you to hold it for a longer time. Also, this innovation is a kind of barrier that prevents lens contamination and protein deposition.
It is important to understand that no protective function of the solution can prevent contamination. Do not neglect the rules of daily lens hygiene, you must regularly change the solution in the container and do not reuse it.
Precautions and contraindications
Before using contact lenses, it is necessary to undergo an examination by an ophthalmologist, who, if necessary, will prompt the necessary parameters for the purchase and give tips on choosing a solution. Individual intolerance to certain components of the drug can lead to serious consequences. The solution for Opti-Free lenses is universal, that is, it is suitable for all types of soft lenses, including silicone-hydrogel ones.
Never use an expired drug. The solution for Opti-Free lenses can be used within six months after opening. After this period it must be disposed of.
Solution for contact lenses "Opti-Free" is not intended for heat treatment. It must be stored at room temperature out of the reach of children; Do not boil or freeze - this may adversely affect its disinfectant properties.
Summarizing
If for some reason you prefer contact lenses rather than glasses, you should approach the choice of your doctor, optics, the lenses themselves and the solution for them with all responsibility. When switching from one product to another, an ophthalmologist also needs to be consulted.
Precautions should not be neglected, because health determines the quality of life. An expired or fake solution or the lenses themselves can only impair vision, leading to serious diseases of the cornea.
Always deeply study the product before buying, read the instructions for use and strictly observe the terms of wearing and storage. It is strongly not recommended to use products after the expiration date, especially when it comes to goods for health and hygiene.
Follow all possible recommendations in order to avoid infection. Conjunctivitis is the most common problem in people using contact lenses, which can be prevented by using the Opti-free lens solution, which effectively eliminates the causes of the disease, microorganisms and other irritants.
