Is the eye suitable for the use of contact lenses? This can determine whether the eye is suitable for the use of contact lenses and measure the correct values for contact lenses (diopter, radius, diameter, cylinder and axis). Among other things, the amount and composition of the tear fluid also affects the choice of the right contact lens.
Why are glasses and contact lenses unproblematic? In principle, a combination of glasses and contact lenses is unproblematic. Many contact lens beginners wear the two visual aids alternately to slowly accustom the eyes to lenses.
What are contact lenses for people with defective vision? Contact lenses are an invisible visual aid for people with defective vision: the small, round plastic shells are inserted by the person concerned slbst into the eye, where they float on a tear film in front of the cornea.
What are contact lenses usually necessary?
Contact lenses are usually necessary when someone is ametropic and cannot or does not want to wear glasses for vision correction. They are suitable for people with the following refractive errors: Contact lenses, of course, do not provide a cure for the refractive errors.
Is optician or ophthalmologist preferable for contact lenses? The simplest answer to the question of whether an optician or an ophthalmologist is preferable for contact lenses is: If the eye is healthy, a visit to the optician is also sufficient. The ophthalmologist is a medical doctor and the contact person for all matters relating to eye health. Opticians are competent contacts,
What is a contact lens claim?
For example, your ophthalmologist must have diagnosed a nearsightedness or farsightedness of at least eight diopters. Furthermore, there is an entitlement to the provision of contact lenses, among other things, in the case of: irregular astigmatism (contact lens must promise an improvement of at least 20 percent compared to glasses)
Is only one of the two contact lenses unusable? If only one of the two contact lenses is lost or becomes unusable for reasons beyond the control of the insured, the allowance is half the amount required for the lenses.
How long will the contact lenses last usable? The daily wearing time varies and depends on the contact lens material and the contact lens tolerance of the eyes, but can be up to 12 hours. The contact lens specialist usually checks annually whether the lenses can still be used without any restrictions.
What is the upper limit for contact lenses? Currently, the upper limit for reimbursement per contact lens is approx. 164,- Euro (as of March 2018). Costs for care products are not covered. In addition, contact lenses can be claimed as an extraordinary burden in the area of special expenses for tax purposes.
What are the costs for contact lenses?
Cost of contact lenses - daily lenses, monthly lenses and annual lenses. So you can expect costs of about 90,- Euro upwards and possible additional costs for fitting of about 70,- Euro per lens. However, they can still be cheaper than monthly lenses in the long run, depending on how often you would use them.
What are contact lenses?
Contact lenses are small, curved lenses that float on the cornea (or more precisely: on the tear fluid that wets the cornea). The shape of the contact lens is flattened in the middle for myopia ( concave, see figure).
What materials are included for hard contact lenses? Materials for hard contact lenses are generally polymers containing methyl methacrylate to improve mechanical stability and optical properties, as well as siloxane and, in most cases, fluorine compounds, both of which increase the oxygen permeability of the material.
Why are soft contact lenses recommended?
This makes rigid lenses also recommended for those who wear contact lenses for a long time every day. Because hard contact lenses require acclimation, soft contact lenses are more beneficial for occasional wear.
What are soft contact lenses for corneal shape? Soft contact lenses are significantly more flexible and adapt well to the shape of the patient's cornea due to their elastic properties. This naturally increases wearing comfort, but they are also more susceptible to drying out and infection.
Why are soft contact lenses suitable for oxygen? The higher the water content, the more permeable these contact lenses are to oxygen. Due to their flexibility, soft contact lenses adapt well to the shape of the wearer's cornea. This increases wearing comfort and is the reason why they are usually well tolerated the first time they are worn.
How many contact lenses are made of silicone hydrogel? Nine of them are made of silicone hydrogel, the other seven models are made of hydrogel. They therefore adapt precisely to the shape of the cornea. This is also the reason why soft contact lenses are particularly comfortable to wear, explains ÖKO-TEST.
Why are contact lenses not good?
However, contact lenses are not well suited for all patients in everyday life. In dusty environments or when handling certain chemicals, such as in the workplace, there is a risk of foreign bodies getting between the lens and cornea, causing injury.
What is the best contact lens in the eye?
Even the best contact lens is a foreign body in the eye that interrupts the natural moisture film. Therefore, to maximize comfort, you should choose a lens with high oxygen permeability, which prevents the eyes from drying out.
Why is a toric contact lens essential?
Toric contact lenses can compensate for corneal curvature due to their special shape. However, to do this, they must fit exactly to the individual corneal surface of each eye. Therefore, a fitting by an experienced contact lens specialist is essential.
What are toric contact lenses?
TORIC CONTACT LENSES Toric contact lenses are used to correct astigmatism. They compensate for the irregular curvature of the cornea and thus enable clear, sharp vision. This defective vision is congenital in many people.
Which health insurance companies reimburse the costs for toric contact lenses?
Private health insurances and supplementary insurances reimburse the costs of the lenses depending on the insurance and tariff. The cost of interocular toric lenses for cataracts is also not fully reimbursable according to experience. Toric contact lenses buy online?
What is a regular contact lens?
Regular contact lenses are spherical, which means they are shaped like a sphere cut in half. The shape of a toric contact lens, on the other hand, is a torus, which you can imagine as a donut. If you now cut a slice off the side of the donut, you have the shape of a toric contact lens.
Is a contact lens fitting required?
One thing is certain: A contact lens fitting is necessary for all contact lenses, but essential for toric contact lenses! Toric contact lenses should always be fitted by an ophthalmologist or optician, otherwise the toric contact lenses will not sit optimally on the eye.
