The effects of persistent drought on Mediterranean forests
The use of contact lenses is now widespread but few people use them properly. These objects are specially designed to be placed on the ocular surface and they require a prescription from a contactologist, as well as following guidelines and responsible use. In addition, the use of contact lenses generates a lot of doubts:
We talked about all this with Eloi Rodríguez, head of the Contactology Department of the Barraquer Ophthalmology Centre and with Dr. José Lamarca, ophthalmologist in the Cornea and Ocular Surface area of the same Centre. Listen to their recommendations in Contact Lenses: keys to use them properly and avoiding complications # 8, the last episode of our podcast Decansa la vist (Rest your eyes).
When to see the contactologist
Although access to contact lenses is easy, they can even be purchased online, every contact lens wearer should previously consult an ophthalmologist, to assess eye health issues, and also a contactologist, who is the specialist in charge of prescribing them, personalizing them according to the characteristics of each patient and giving them the guidelines and indications to use them properly.
That is why it is essential to go to a specialized eye health centre before starting to use contact lenses or if their use has already started but without the supervision of a specialist. As Rodríguez affirms, “the lenses that are well indicated, adapted and used in accordance with hygiene rules do not cause problems. The real risk almost always appears due to an error made during use”.
Complications with the lenses
These are the main complications associated with the misuse of contact lenses:
Don't bathe with contact lenses still on
Neither in the sea, nor in the pool, nor in the shower at home. Although the water is drinkable, contact of the lens with the water is a risk factor for the appearance of the aforementioned complications. The benefits that contact lenses provide, such as getting out of the water and finding the towel, are totally insignificant if you know the real danger of bathing with them, so taking the risk is not worth it.
Contact lenses are made of oxygen-permeable materials to provide maximum oxygenation to the cornea and our ocular surface. They are made of plastic materials with a variable percentage of water that give them that flexibility and softness to the touch and act like a sponge in contact with water, absorbing and retaining any germs or bacteria that can damage our eyes. Therefore, it is important to avoid contact with water while wearing contact lenses.
Other recommendations would be replace contact lenses when required, maintain good hygiene guidelines and not exceed the time of use, indications that must be personalized with each patient according to their controls.
