The Use of lens edger in the Technology of Contact Lens
The contact lens is a modern optical medical aid we read on Wikipedia. However, do we know for whom the lenses are intended, what to choose when choosing them, what are the possibilities and health restrictions for their use? Information often differs or is completely absent.
Dioptric Glasses Utility
Right now, in the days of skiing, swimming and indoor sports, putting off dioptric glasses can be useful. So we went to the specialists. Ask yourself what the contact lenses really are.
The first step, but not the last, to the proper and healthy wear of contact lenses is to order an optometrist for examination and first application. The first application may only be performed by a registered non-governmental health facility.
The Right Direction
Ordering an optometrist takes two minutes on the phone, but it saves hundreds of crowns and many health complications that can occur when the contact lens edger is incorrectly selected. The Optometrist gives you time and is very thorough. The choice of contact lenses is preceded by an interview in which the practitioner discovers for what purpose the lenses are to be taken, the diopter and curvature of the candidate’s cornea will be measured and offers several variants. When the customer agrees to the type, the first lenses application will take place, where the customer learns all the manipulations and hygienic habits necessary for healthy wearing of lenses and arranges a check-up.
“Individual care, this is what the user of the contact lenses will appreciate the most. That’s why we put a lot of emphasis on it. The second major advantage of our optics is awards. We can boldly compete with products on the Internet. Thanks to the support of suppliers such as Alcon or Johnson, who want customers to be under the constant supervision of specialists and buy lenses in optics, “says JiríMalinský. If the lens wearer does not comply with regular checks and the rules for wearing the lenses, the risk of irreversible damage to the cornea is compromised. And last but not least, she can not even detect whether she is wearing lenses with current diopters.
The contact lens is almost for everyone
One of the most common myths around the lenses is the correction of eye defects. “It can be said that in diopters up to plus minus ten it is a normal dioptric defect that corrects classic contact lenses.”
For people with short-sightedness, farsightedness, astigmatism or presbyopia, the solution will always be found. The lenses allow them to see sharply across the field of view, distort and do not limit themselves to sports or day-to-day activities. “Contact lenses do not moan, you can wear them under ski or sunglasses, they are very comfortable,” adds the optometrist.
Materials, shapes, wear time – technology has advanced greatly
Historically, it may be interesting that the first contact lenses were made of glass. At the next stage of development, the lenses are celluloid, and hard corneal lenses appeared. Until the invention of Czech professor Otto Wichterle allowed the use of soft contact lenses for the widest public.
The same is with the type of correction. “High-quality vision measurement with special instruments allows you to determine the necessary correction – spherical, toric or bi or multifocal and accurate corneal curvature that is essential for comfort and proper vision with the contact lens,” explains the optometrist.
