Contact lenses are an alternative to prescription glasses, but as their use leads to the emergence of many doubts, since it involves placing something directly in contact with the eye.
Contact lenses have advantages when compared with prescription glasses because they do not break, weigh, or slip on the face, being especially appreciated by those who do not like to wear prescription glasses or practice any sport. However, if not used correctly, the use of a lens increases the risk of sty, red eyes or dry eyes and of more serious problems such as corneal ulcers, for example.
So, to clarify some of the most common doubts, see some myths and truths related to the use of contact lenses:
1. Does wearing contact lenses hurt and cause eye infections?
Wearing contact lenses is not harmful to the eyes, as long as they are used responsibly, respecting the maximum wearing time of 8 hours a day and the necessary hygiene care. Only incorrect use and failure to comply with the necessary hygiene precautions increase the risk of eye infections, caused by the use of lenses. See what care should be taken and how to clean the lenses in Learn All About Contact Lenses.
2. The lens may be lost or stuck in the eye
The fear of losing the contact lens in the eye itself is a common fear, but this is physically impossible, as there is a membrane that prevents this from happening. Rarely, what can happen is the lens folding and getting stuck inside the eyelid (at the top of the eye), which can be easily removed at home.
3. Is wearing lenses uncomfortable?
In most cases and if the eye is healthy, contact lenses are not uncomfortable. The choice of lenses to be used is one of the factors that most contributes to comfort during use, as each type of eye can adapt differently to the different types of existing materials. Generally, the choice of the lens should be assisted by an ophthalmologist or specialized technician.
The discomfort arises only when there are signs of tiredness, itching, redness, watering or feeling of discomfort in the eye and in these cases it is most recommended to stop using the lenses for 1 or 2 days or consult the ophthalmologist if necessary.
4. Does going to the beach damage the lens?
The beach may end up damaging the lenses more quickly, which is due to the effect that sea water salt can have on the lenses, making them dry more easily. This can happen even if you always close your eyes when diving, and the same happens in swimming pools, due to the chlorine and disinfectants that are added in this type of water.
However, whenever necessary the lenses can be used on the beach or in the pool, as long as you are careful to always close your eyes when diving.
5. Can a child wear a contact lens?
Children and teenagers alike can wear contact lenses, as long as they are mature and responsible enough to care for the lenses and do the necessary hygiene. This can often be a good option, as it can help raise the child's self-esteem, who is no longer forced to wear glasses at school, for example.
