Do you hesitate to buy glasses or contact lenses? Everyone suits and suits something different, but the contact lenses have (undisputed) unquestionable benefits. The world of a small rounded “nothing” by prof. Otto Wichterle, launched more than fifty years ago and constantly refined, will bring us closer.
If anyone is used to glasses and would like to “shuffle” on contact lenses, is there a need for a non-routine examination with an ophthalmologist? What does the prescription for glasses and contact lenses differ?
Examination on glasses and contact lenses varies greatly. Contact lens lenses are more extensive and additional information such as eyebrow size and tear quality need to be known. Also, the number of diopters often varies because the contact lenses “lie” directly on the eye, while the glasses have an optical lens edger about 1-1.5’cm away from the eye. Contact lenses can apply, that is to say, in the eyes, only a contactologist. This is either a trained eye doctor or an optometrist.
How much is it difficult to learn with lenses to manipulate?
Deploying and removing lenses from the eye will teach practically everyone, including children. Initially, you need to be patient, but an experienced contactologist will advise the right course and “tricks” that will lead to a successful goal. There are also ways to get over the natural blinking reflex, which makes it harder for us to initially engage. Women are usually better – they have a practice in applying makeup, so the eyelids are better “listening”.
We do not want to give up vision even at an older age
Can contact lenses correct the same eye defects as eyeglasses (including astigmatism)? To what diopter values ??can lenses be used and when it is no longer possible for example for technical or health reasons?
We divide the contact lenses into soft (used by about 95 percent of all wearers) and solid, gas-permeable. These soft lenses are then subdivided according to the material used, oxygen permeability, but from the practical point of view, the most important is the division according to their “lifespan” and the permitted wearing method. Lifetime has the most commonly used soft lenses 30, 14 or 1 day. And the permitted way of wearing is most often daily (from morning to evening) or extended (even overnight, several nights). Most soft lenses on our market will satisfy those who want to get rid of their glasses for a while, including patients with astigmatism. It is possible to order custom lenses outside the normal range. For extreme dioptric values ??or “nonconflict” corneal dimensions, the most suitable solid, gas-permeable lenses are most suitable.
From what age do lenses actually wear? Are there any major differences between lenses for children and adults or older people?
It can apply lenses to people over 15 years of age. The medical contact agent applies lenses even to the youngest, including newborns. There are cases where even small children need to be corrected for proper visual development and glasses are not appropriate. Lenses for children and adults usually differ only in size and number of diopters. New items are now lenses for those who are already in need of reading glasses. They are called multifocal contact lenses.
