Studded lenses in the pool, without a view in the sauna, a slipping glasses or even splintering glasses during sports - these problems have contact lens wearer not. But before the view with contact lenses, the walk to the ophthalmologist. Regardless of short or long-sightedness - most vision defects can also be compensated with contact lenses. Certain eye changes, for example, a higher or rapidly increasing myopia, irregular corneal curvature or greater difference in the side of the refractive error can be optimally corrected only with contact lenses.
What has to be considered with contact lenses?
It is always important to first visit the ophthalmologist. At the first examination, he determines which visual defect is present, whether this can be corrected with contact lenses and whether contact lenses are suitable for the eyes of the person concerned.
The lenses are not only adapted to the individual organic conditions of the eyes, but their use is also considered: is the visual aid needed, for example, for VDU work in the office or for a particular sport? Should she be worn occasionally or always? The specialist finds the appropriate solution after thorough examination and consultation.
Meanwhile, there is even the possibility to buy contact lenses in the drugstore or supermarket. But the suitability for contact lenses and the right fit, strength and the right material can only be determined by a trained specialist. Contact lenses that are not adjusted professionally, can permanently damage the cornea and thus threaten the eyesight in the long term.
Contact lenses from the supermarket?
Anyone who wants to switch from glasses to visual lenses will not find the right products in the self-service market. You can not simply transfer the spectacle thickness to the values of the contact lenses, as they are at a much closer distance to the focus of the eye. Also, the curvature of the cornea and the material compatibility must be checked before the first use necessarily.
Even for experienced contact lens wearers who know all these dimensions accurately, the uncritical grip on the supermarket shelf can be dangerous. Cheap contact lenses are a ticking time bomb on the cornea, because they often have a wrong fit and let in too little oxygen. In the eye, they either sit too loose, too tight, or even suck on the cornea. If the oxygenation of the eyes is suppressed by badly fitting contact lenses, the cornea swells and becomes susceptible to microorganisms. Removing the fixed contact lenses may cause minor injuries.
Unfortunately, those who want to save on contact lenses often save at the expense of their health. Because cheap lenses are made of inferior material and can harm the eye.
Cost coverage by the health insurance?
Contact lenses can only be prescribed for certain medical indications at the expense of the health insurances. This includes:
- Farsightedness from 8.0 diopters
- Irregular corneal curvature, if this results in an at least 20% improved eyesight compared to spectacle lenses
- Corneal curvature with straight axis position from 3.0 diopters
- Corneal curvature with oblique axis position from 2.0 dioptres
- Keratoconus (disease with central conical distension of the cornea)
- Lenslessness, e.g. After cataract surgery, when no artificial lens could be planted in the eye
- different refractive errors of both eyes with a difference of more than 2.0 diopters
- All other eye diseases in which a significant improvement in vision is achieved with the contact lens compared to the glasses.
