Contact lenses for dry eyes
introduction
The symptom of dry eye is particularly limiting for contact lens wearers. If the eyes are too dry, this can usually be traced back to a wetting disorder of the eye, which arises from the fact that the tear film is either put together incorrectly or simply formed too little. In order to prevent conjunctivitis from occurring, the deficiency must be remedied as quickly as possible.
Otherwise, in addition to conjunctivitis, corneal inflammation can also occur, which can leave permanent damage to the eye.
causes
There are several possible options for the dry eye causesthat can all appear together. These include the following:
- Rheumatoid arthritis
- Eye surgery (Laser surgery, Cataract surgery, Etc.)
- Autoimmune diseases (e.g. Sjogren's syndrome)
- Vitamin A-Defect
- Allergies
- Rosacea
- Inflammation of the eyelid margin (blepharitis)
- Medication (Birth control pills, beta blockers, etc.)
- Hormone fluctuations / changes
- low humidity / air conditioning (airplane, car, etc.)
- contact lenses
- Environmental pollution
- frequent screen work
treatment
By special Eye drops for dry eyes and Eye gels the lack of a tear film in the eye can be compensated artificially. It is important here, especially with frequent use, that the funds no preservatives as these can accumulate in the contact lens and also cause damage to the eye.
Proper contact lenses
There are contact lenses out different materialsso that the right material is individually selected that fits the eye of the person concerned as well as possible. Due to external influences such as heat or wind, the contact lens materials lose fluid over time, which they then compensate for by absorbing tear fluid. The eye then lacks this tear fluid as a tear film, since it is possible that too little tear fluid has already been produced for the eye's own needs.
Of the Water content of the contact lenses is different and the more liquid the lenses have, the more can evaporate, so that the Lenses with a high water content draw more fluid from the eye than lenses with a fundamentally lower water content.
Conventional lenses made of so-called Hydrogel have a water content of about 50% and should maximum 10 hours be kept in mind.
Silicone hydrogel contact lenses however, have a water content of about 30% and the maximum wearing time can be up to 14 hours be expanded.
However, the shorter contact lenses are worn, the better it is for eye health. If with closed eyes If you rest or go to sleep, the contact lenses must be urgently removed from the eye so that the eye's metabolism can continue undisturbed.
Hyaluronic acid as a helpful ingredient
hyaluronan is an endogenous substance that is already widely used in medicine and cosmetics.
There are now manufacturers who incorporate hyaluron in the salt form of hyaluronic acid, as hyaluronate, into contact lens material due to its material water-binding property. In this way, the contact lens is intended to ensure constant moisture in the eye without removing moisture from the eye itself when it evaporates.
Important with these Gel contact lenses is to use them for cleaning and disinfection hyaluronic care product This is the only way to maintain the hyaluronic acid in the lenses and to enjoy the benefits of the special contact lens material.
Hyaluron-containing care products are also suitable for cleaning, disinfecting and care for all other contact lenses, as this can improve tolerance when wearing contact lenses.
Basic prevention of dry eyes
If you have some behaviour rules adheres to, the symptoms with dry eyes can at least be reduced:
- regular ventilation (avoids dry air)
- Avoid drafts
- consciously regular eyelid closure (often blink!)
- Avoiding smoky rooms
If dry eye complaints persist, an urgent need Ophthalmologist be visited, as various diseases can also be responsible for an increased feeling of dryness in the eye.
