Laura González, an IMO optometrist: "Despite our efforts to raise awareness of the problem, patients still forget to take their contact lenses out before going to bed because they’re so unobtrusive and comfortable"

The ophthalmology item begins at 07:16. Opticians discourage the use of extended-wear contact lenses, because they increase the risk of developing corneal infections.

Experts also point out that daily-wear lenses can cause damage as well. Some microorganisms use contact lenses as a means of entering the cornea and can cause serious infections, resulting in eye injury or even vision loss. Using soft 30-day contact lenses multiplies the risk of developing these disorders by five.

"I felt a pricking sensation and applied some artificial tears, but it got worse. After a few hours, I couldn’t stand the light," explains a patient affected by the use of contact lenses. As they are much cheaper than daily-wear lenses and more comfortable than the semi-rigid variety, some patients prefer them, but ophthalmologists warn that users should know what precautions to take when using them. 4 out of 10 wearers of these lenses keep them in while having a nap, because many of them have not been informed of the risks associated with using them incorrectly.

Dr José Luis Güell from IMO: "It can be very difficult to control an infection, either because it is treated late or because the best treatment does not have the desired effect and the infection doesn’t clear up quickly. As a result, it can not only affect the ocular surface, but also the rest of the eye." It is important to use contact lenses correctly, whether they are daily or extended wear. Ensure good hygiene and never reuse single-use lenses, change the fluid and case every month.
