Types of lenses for different visual needs and corrections
Single vision lenses
Single vision lenses are used to correct vision at one distance.
Near-sightedness (myopia) correction
Myopia is the most common visual defect. People afflicted with myopia see near objects clearly, but they have problems when reading texts that are located in the distance (blackboards at school, road signs, etc.).
Myopia is corrected with divergent lenses
with minus diopters.
Far-sighted people have troubles with focusing their eyes at near objects - for example reading is very difficult for them.
Hypermetropia is corrected with convergent lenses
with plus diopters.
Progressive lenses are used to correct presbyopia, when the eye loses its ability to focus on near objects due to age-related loss of elasticity of the crystalline lens. It is a natural and unavoidable process with usual onset between 40 and 50 years.
A progressive lens is the only spectacle lens that gives you comfortable and clear vision at every distance
- near, intermediate and far - with only one pair of glasses
Modern technology allows us to produce lenses without a visible transition between the different zones. Unlike bifocal lenses, progressive lenses do not have a raised and visible near zone, which makes them very aesthetically appealing
Your progressive lenses look just like
single vision lenses and provide you with an undisturbed visual contact with your enviroment.
There is a wide selection from different kinds of progressive lenses. All of them guarantee a maximum visual and aesthetic quality.
It is the best, most advanced solution that allows you to avoid incessant switching between different types of glasses.
Degressive lenses are suitable for office enviroment
and everywhere you need a sharp vision at an intermediate and near distance.
Compared to standard progressive lenses, degressive lenses feature wider near vision and a greater sharpness than a common single vision reading lenses.
You can reach near vision with very short and natural eye movement. Intermediate vision is accessible with a usual position of the eye, which means that your activities that require switching between near and intermerdiate vision are much more comfortable and less exhausting.
Degressive lenses will prove especially beneficial, if you:
Perform activities where you need to see clearly at a near distance (and not just at a near distance) for a long time.
Are a bifocal lenses wearer and demand also focus at an intermediate distance.
Are a progressive lenses wearer and are looking for a more effective solution for working with objects located at a near distance.
You are an avid computer user and you need more comfortable solution for quality vision.
They improve vision only at two distances - near and far.
Bifocal lenses are still advanced, yet nowadays an obsolete solution. The lens is visibly divided into two areas where the near zone (the segment) is raised above the surface of the lens, which does not appear very aesthetic.
