Today, like 4 million Frenchmen, I wear contact lenses and I can not thank enough Adolph Eugene Fick who invented them in 1887 (#historyhistorique always useful in society). Indispensable during certain activities, especially sports, contact lenses are more practical and more aesthetic than glasses but require precautions of use and strict hygiene .This summer and even more so if you swim, be uncompromising about the rules of hygiene of wearing contact lenses . I thank Dr. Gogneaux, ophthalmologist for this extremely complete article that tells you FINALLY how to take good care of your lenses and therefore your eyes!
What are the different types of contact lenses?
Soft lenses are highly oxygen-permeable hydrogel silicone lenses (this is called Dk / e).
There are different categories:
– Daily disposable lenses , to renew every day. They must be discarded every day as soon as the lens is removed and never reused.
– Lenses with frequent renewal , to renew according to brands, 2 weeks, 1 month or 3 months after the opening of blisters. – Traditional lenses, with annual renewal.
Rigid Permeable Gas Lenses (LRPG)
Their frequency of renewal varies from one to two years, sometimes less in certain particular contexts.
To know that soft lenses are more of a source of complications than rigid lenses!
You can also have an allergic reaction:
Especially the maintenance product, that’s why you should not change the brand of rinse product at any time.
In practice: Tips for using your lenses well.
The most common symptom when an eye infection occurs is a feeling of dryness. A feeling of ‘ discomfort during installation can correspond in turn to tears, hypersensitivity to the product or dust. Similarly to removal may be corneal erosion, ulcer or infection. Discomfort after several hours of exposure is due to dryness (lack of tears) or debris on the lens.
Excessive dryness of the lenses may require artificial tears or decreased wearing time.
Who prescribes and how?
It is only and only the ophthalmologist who prescribes lenses after a complete examination. He will make sure of the absence of contraindications = dusty environment, infectious antecedents, allergy, bad hygiene, bad statics of the eyelids … Then one will proceed to the adaptation itself by tests which make it possible to determine the characteristics of the lens with a control exam at 1 month.
Strict adherence to maintenance modalities can limit the risk of infection and maintain the visual qualities and comfort of your lenses.
- No permanent wear without the permission of the ophthalmologist, respect the duration of use and no port at night !
- Do not wear contact lenses in seawater / swimming pool / sauna / steam room / in case of pollution / strong wind / sand.
- If possible avoid annoying situations such as air conditioning and provide a pair of glasses to be able to remove the lenses at any time.
- Use a branded cleaning product!
- For effective maintenance of your lenses, you are advised to massage and rinse them with the solution daily.
- The case must also be rinsed with the appropriate solution and not with tap water … and changed every month!
