Bausch + Lomb - contact lenses for each

One of the oldest operating companies of the United States, Bausch + Lomb, occupies the leading position in the production of vision correction. Sales of contact lenses bring her 31% of revenue. The most demanded contact lenses Optima, Bausch + Lomb Pure Vision, Soflens and MultiVision.

History of creation

The company was founded by a German native John Bausch in 1853. He discovered optics, and later a friend Henry Lomb became his full partner.

The enterprise manufactured rubber frames, binoculars, microscopes, and other precise optics, including for military purposes. This was facilitated by the cooperation with Carl Zeiss, the leader in the production of optical instruments. The company was among the first manufacturers of sunglasses, produced for the US Air Force (Ray-Ban).

In 1966, the company obtained a license for the production and trade of contact lenses from water-absorbing hydrophilic material. In 1971, 100 thousand pairs of Softlens lenses were sold.

In 1987, the FDA approved the sale of lenses with Teflon-like coating, preventing the deposition of protein and making the lens more convenient.

Lenses Soflens 66, which became widely popular, were released in the early 90's. And in 1993, thanks to the acquisition of Laboratories Conoptica and Polymer Technology, the first oxygen-permeable means of vision correction appeared. At the end of the last century, a technological breakthrough occurred - Bausch + Lomb Pure Vision contact lenses were designed for permanent wearing.

Production facilities and trading enterprises of the company, whose staff exceeds 10 thousand employees, are located in 25 countries. The headquarters is based in Rochester.

Main characteristics of contact lenses

Lenses can be soft and stiff. Rigid lenses are durable, durable, smaller, better "breathe", so they wear longer. However, they are less comfortable, they can change the shape of the cornea, reducing the visual acuity in the glasses.

The main materials used in the manufacture of soft lenses are hydrogel and silicone hydrogel. Hydrogel passes oxygen worse, so the maximum period of safe wearing of such lenses does not exceed 15 hours. Its excess is fraught with hypoxia of the cornea of the eye.

According to the frequency of replacement contact vision correction devices are divided into one-day, weekly, monthly, quarterly and annual. One-day most hygienic - care is not required and discarded after use.

The mode of wearing can be daytime (up to 15 hours), prolonged (up to 7 days), flexible (up to 2 days), continuous (up to 30 days) and night (to correct the shape of the cornea during sleep).

Design can be spherical, toric and multifocal. Myopia and hypermetropia are corrected by spherical, astigmatism - toric, age-long-sightedness - by multifocal lenses.

The presence of a UV-filter will protect the eye from ultraviolet radiation.

Color lenses imitate the iris and allow you to change its color.

Production of the company

The company produces products for vision correction with farsightedness, nearsightedness, astigmatism, presbyopia, cataract, keratoconus and other eye diseases.

Optimum choice for people who prefer lenses of planned replacement, are contact lenses Bausch + Lomb Optima FW. Choosing a permanent wearing or high-quality vision is suitable lenses PureVision and PureVision2. Suffering astigmatism will help another product Bausch + Lomb - contact lenses Sof Lens Toric. Age-related farsightedness can help fix SofLens Multi-Focal. Young people like the colorful contact lenses Bausch + Lomb Sof Lens Natural Colors.

Optimal

Contact lenses Bausch + Lomb Optima FW from the hydrogel are designed for wearing in the day no longer than three months. Oxygen permeability is 24,3 DK / t. The liquid content is 38.6%.

Characteristic differences:

  • Method of production - centrifugal casting of "polymakon", non-ionic strong material;
  • Smooth surface, reducing the level of protein deposits;
  • Optimal mobility and alignment;
  • Ease of handling, provided by light pale blue tinting.

PureVision

Produced from silicone hydrogel "balafilkon A". Should be worn constantly or in the daytime not longer than one month. The water content is 36%. The permeability is 112.0 DK / t. The design is aspherical. Tint is light blue.

Benefits:

  • Front aspheric optics improves the quality of vision in poor lighting conditions and reduces spherical aberrations;
  • Use of a combination of a hydrophilic hydrogel and a high oxygen permeability silicone (AerGel technology) opens up natural oxygen access to the eye cornea and constantly moistens the lenses;
  • The contact lens surface is treated with plasma, which gives it an ideal smoothness and high wettability;
  • The thickened middle and thin rounded edges provide excellent mobility and constant movement of tear fluid under the contact lens.

PureVision2

Novelty Bausch + Lomb - contact lenses Pure Vision 2 - aspherical light blue lenses from silicone hydrogel "balafilkon A" are designed for permanent wearing or wearing in the day no longer than a month. The liquid content is 36%. The permeability is 130.0 DK / t.

These lenses are designed for PC users, motorists and anyone who needs clear vision in conditions of artificial or insufficient daylight. Their differences:

  • Special optics of high definition reduce spherical aberrations, glare and halos, which makes it possible to see clearly, without rainbow circles and glare, even in poor light conditions.
  • A small thickness that makes the lenses almost imperceptible.
  • Smoothness of the surface and rounded edges, ensuring comfortable wearing.
  • High oxygen permeability of silicone hydrogel, which reduces the likelihood of hypoxia and ensures that the eye receives a sufficient amount of oxygen.

Colored

Color contact lenses Bausch + Lomb Sof Lens Natural Colors from the hydrogel "polymakon" are designed for wearing in the afternoon with a replacement every 3 months. The liquid content is 38.6%. The oxygen permeability is 14.0 DK / t.

They differ in the following features:

  • Nine shades: platinum (gray), aquamarine (turquoise green), indigo (purple), jade (light green), Pacific Ocean (blue), amazon (green), "Topaz" (blue), "emerald" (dark green), "India" (walnut).
  • A special application of color and limbal ring makes the eye color close to natural.
  • Smooth surface, resistant to protein deposits.
  • Resistance to dehydration.
  • Optimal mobility and alignment.

Sof Lens Toric

Another product Bausch + Lomb, contact lenses Sof Lens Toric, is a toric lens from the hydrogel "alphaphylcon A". Wearing in the afternoon and monthly replacement. The permeability is 16.0 DK / t. The liquid content is 66%. Are intended for people suffering from astigmatism.

The advantages are as follows:

  • The unique double curvature of the lens with a flatter surface in the center and steep edges makes it possible to achieve the best possible centering and clear vision.
  • Good stabilization of the axis is achieved by thickening from the center to the edge of the contact lens.
  • The radius of the outer and inner parts of the lens is chosen to reduce the thickness and optimal lens stability.
  • The reduction in weight, as well as the rounded edge of the lens, results in a comfortable wearing and optimal lens mobility.

Sof Lens Multi-Focal

Suffering from age-long farsightedness will help the next product Bausch + Lomb - contact lenses Sof Lens Multi-Focal, light-blue multifocal lenses from the hydrogel "polymakon B". It is recommended to wear the day and a monthly replacement. The liquid content is 38.6%. Oxygen permeability is DK / t.

Benefits:

  • Balanced mass distribution, which improves the centering and operation of aspheric optics.
  • A wide transition between the near and far optical range ensures clearness of vision regardless of distance.
  • The transition zone smoothly changes the focus between the near and the far, keeping the clarity at intermediate distances.
  • The rounded edges of the contact lens gently slide over the eye cornea.

Here only a small part of the company's products is shown, but you can be sure that what contact lenses are not purchased, they will always be of high quality - the legendary American quality of one of the oldest US companies.
