What are the best lenses for the eyes?

Fitting lenses is a responsible business. While it is possible to settle on the desired model, sometimes it is necessary to re-measure dozens of proposed samples.

Even taking into account the fact that before purchasing accessories for optical correction, they turned to an ophthalmologist and underwent all the necessary examinations, the models he proposed may turn out to be unsuccessful.

The rating of contact lenses depends not only on the manufacturer, but also on the individual reaction to the optical corrector.

Soft or hard contact lenses?

Soft optical accessories are comfortable, more comfortable to wear, they get used to them almost from 1 try-on, however, they can change shape when the cornea dries out. At the same time, they have increased absorbent properties, saturated with vapors from the air, in which chemicals are also dissolved. When playing sports, it is preferable to choose soft contact lenses.

Rigid ones are more reliable, they have a longer service life, the image obtained with their help is sharper and clearer. They help solve most of the vision problems that soft models cannot cope with - for example, with astigmatism. But it takes longer to get used to them, during sleep they must be removed. But when dirty, they are easier to clean.

Rigid models put pressure on the cornea of the eye, which increases the corrective effect, but the risk of injury to the eyeball increases.

The choice of the best accessories in this regard depends on your own feelings and vision problems - soft models help correct only myopia and farsightedness, they are not able to cope with astigmatism.

Currently, the selection according to the stiffness parameter is facilitated - contact lenses have been developed that combine 2 types of materials - silicone and hydrogels: the center is made of gas-permeable silicone, and the edges are soft, increasing comfort during use.

Duration of use

Which models are better to choose, disposable or reusable?

Even if it is economically possible to purchase more expensive reusable accessories, you need to decide on the possibility of care. After all, if you neglect the recommendations for replacing the storage tank, do not replace the solution in time, do not handle and clean the optics as carefully as required, ophthalmic problems will intensify.

By the term of use, models can be classified according to the following parameters:

  • reusable:
  • 1-2 weeks;
  • monthly;
  • 3-6 months;
  • for annual replacement;
  • disposable.

Those who already use this accessory are not advised to purchase optics with a period of use more than 3 months - in this case, the possibility of deformation of the accessory is minimal.

Modes of use

What are the best contact lenses - the choice regarding the mode of use.

Can choose:

  • daytime - they are put on in the morning and removed only in the evening, before going to bed;
  • prolonged - they can not be removed for a week;
  • flexible soft - they are worn for 2 days;
  • for permanent wear - within 30 days.

The most gentle to the eyes are accessories for the daytime regimen, prolonged or designed for permanent wear are more comfortable - especially on business trips, on the road, during rest.

The main parameters of contact lenses

When choosing optics, a very important parameter is taken into account - moisture content:

  • highly hydrophilic - their water content is over 50%;
  • low hydrophilic - the water in them is less than 50%;
  • the average water content is at the level of 50%.

The higher the moisture content, the lower the likelihood of developing dry eye syndrome.

Oxygen permeability coefficient - the more oxygen enters the eyes, the less the possibility of irritation. For accessories made of silicone hydrol, this figure is higher.

It is impossible to choose optical correctors with optimal performance - high oxygen permeability and high hydrophilicity at the same time. Therefore, a suitable option will have to be selected empirically.

The radius of curvature and diameter of contact lenses are also very important parameters. They can only be determined by an ophthalmologist. Usually, consultants in salons advise to purchase optics with standard parameters that suit many - with a diameter of 14 to 14, 2 mm and a radius of curvature of 8, 4-8, 6.

However, it is very likely that the standard sizes will not work. These parameters do not always correspond to individual eye sizes.

If it is not possible to consult an ophthalmologist, or there are no usual models in the salon, then you should focus on the initial measurements, according to which optical correctors have already been selected. If the fit of the previous model was comfortable, but it is not available, you can purchase the following, differing by 0.1 mm in size.

The optical power of the lenses must match the visual acuity. It is undesirable to use optics that completely correct vision. In this case, the eye muscles "break down", and as soon as the correctors are removed, the visibility will be drastically reduced. The eye muscles have to work constantly, otherwise the problems will increase.

Additional lens functions

Which lenses to choose depends on the additional function of the optics.

  1. Protection against excessive UV radiation. However, do not rely on optics - since they do not completely cover the eyeball, they cannot provide 100% protection. It is impossible to do without glasses.
  2. Change in eye color. The coloring layer does not pose a threat to eyesight, it does not come into contact with the cornea, but is inside the accessory. The shade or color is matched to templates.

However, you should not radically change the color of your own eyes. Better vision is provided by tinted lenses; with a radical change in image, visual function deteriorates.

The best lenses for the eyes

Currently, the following manufacturers offer their optical accessories:

  • CIBA Vision - lenses have high oxygen permeability and high biocompatibility;
  • Johnson & Johnson is an acuve brand;
  • Baush & Lomb - manufactures optical accessories for day and night correction;
  • Sauflon Pharmaceuticals Limited - Sauflon brand optics;
  • Clearlab UK Ltd specializes in spherical or toric lenses for daily replacement;
  • Cooper Vision;
  • Maxima Optics;
  • Likon is a Ukrainian company.

All these companies offer decent and competitive products of various types and types. However, the best contact lenses for the eyes cannot be selected based on the reviews of friends or on the Internet, which optics to buy can only be determined empirically.

Before paying for the goods, it is necessary to check the integrity of the packaging, read what is written on it - all the specified parameters must correspond to the quality of the visual function.

You should not rely on the opinion of the company's consultants - they rarely have medical education, and it is almost impossible to find a competent ophthalmologist among the employees. Employees receive a certain percentage of sales, so they try to sell more expensive models, the purchase of which in some cases is unjustified.

You can rely on their recommendations, however, which product to choose, you need to determine yourself.

What advice can you give to a “novice user”? Buy optical accessories for daily replacement, and when your eyes get used to it, think about more expensive models.
