Frequently Asked Questions



DIOPTER
Diopter in optics is a unit for measuring the optical force of a lens. 


MYOPIA
Nearsightedness, also called myopia (from Greek: myopia, myopia, meaning myopia) is a type of anomaly, reduced visual acuity, where the image occurs in front of the retina.
The reason for this is either the protruding eyeball, which causes the falling rays to break before reaching the retina, or a variety of irregularities in the cornea itself, leading to incorrect and chaotic refraction of the rays. For this reason, people with this defect see as misty as misty. They see a lot better around than far. 


Hypermetropia
Hypermetropia (Hypermetropia) reduces visual acuity due to less eyeball length or less refractive power of the ophthalmic lens. The image occurs behind the retina and if the violation is poor, it is compensated by accommodation. As aging progresses, accommodation is weakened, age-old (presbyopia) is getting. Kidney scarring is usually a congenital anomaly of the refractive power of the eye and affects visual acuity when viewed away and to a much greater extent by watching nearby.
 
 


Presbyopia
Presbyopia (a Greek ambassador, an "old man"), also known as senior farsightedness, is a condition of the eyes, which usually begins to develop after the age of 40 and progresses to 60 years of age. At the initial stage of presbyopia development, alterations lead to reduced visual acuity when viewing nearby (35-50 cm). With further development of presbyopia, these changes may also reduce visual acuity when viewed away, as this is more often due to overlapping hidden hyperopia. Depending on the level of presbyopia development, close-range goggles, mid-range (70cm - 1.5m) and far-field goggles are defined. In this age range, each person needs to check their eyesight with an ophthalmologist and adjust their glasses in a timely fashion every 1-1.5 years.
Presbyopia is not a disease and should not be seen as eye aging. This is a normal process and the smallest problem in ophthalmic practice.

How can we protect our eyes from the computer?
The sources of blue sunlight, artificial lighting and the most influential devices with digital display: laptop, desktop computer, tablet, smartphone, LED / LCD TV and more.
Blue light is one of the reasons for the increase in age-matched macular degeneration (AMD) patients.
In this connection, a new generation of coatings has been developed, which blocks the blue spectrum to 100% and prevents blue light from penetrating to the bottom of the eye and causing damage.
It is especially important for children to wear glasses with such protection, as studies show that prolonged exposure of the child's eyes to blue light leads to unlocking of myopia.
The special gloss-reducing protective coating, providing outstanding contrast when working with a laptop, desktop computer, tablet, smartphone, LED / LCD displays, artificial LED lighting, and driving.
 
 


How can I measure my interplanar distance?
You can measure it using a line and a mirror.
Place the beginning of the line just below the center of the pupil, look straight ahead and read the distance to the center of the other pupil. The same distance can be measured if you measure the distance from the beginning of one to the beginning of the other pupil. Ask your relative to measure your interplanar distance with a ruler.
In the event that you are going to have a look at it, ask your eye care professional to measure and prescribe your interplanar distance.



How do I read my prescription for glasses?
The Eyewear Recipe is a table of values ​​describing the adjustment you need.
The table consists of two rows, one for the right eye and one for the left eye.
Four columns that contain information about the value of the necessary adjustment.
Sph or Sphere describes the value of your myopia or farsightedness -
values ​​can be positive (+) or negative (-).
Cyl or Cylinder describes the value of astigmatism -
values ​​can be positive (+) or negative (-).
Axis (Axx) records the astigmatic correction axis - measured in degrees from 0 ° to 180 °.
Add - add-on for close-range / mid-range glasses. Determine depending on what you need or
daily reading distance, computer work, etc. It is written for reading glasses, bifocal or progressive glasses.
Sph + Add = The sum of your diopter to close. If there is astigmatism (Cyl), its value remains unchanged.
O.D. - means the right eye
O.S. - means the left eye
PD (Dp) or Pupillary Distance - Intergonal distance is the distance between the centers of the two pupils measured in millimeters,
ranges between 54 and 70 mm. The intersection distance is necessary for the correct manufacture of all types of dioptric glasses.
