the consequences of incorrect use of contact lensesContact lenses are an item conceived to provide comfort and improve the vision of users as well. The contact lenses need to be treated according to the basic hygienic requirements, in order to provide the eyes with both comfort and health.

Users of contact lenses often make several mistakes:
  • They utilize alternatives to glasses regardless of contraindications - allergies, hormonal disorders, inflammations.
  • They do not follow the recommendations of the manufacturer regarding the contact lenses - they ignore both the expiration date and the need for daily treatment, and also use to wear the contact lenses while sleeping.
  • They wear the contact lenses although they feel discomfort.
Some of the consequences of an incorrect use of contact lenses are listed below:
  • Irritation, burning, sore eye.
  • Feeling of the presence of a foreign body within the eyes.
  • Hypersensitivity to light.
  • Reddening.
  • Increased tearing.
  • Excessive dryness.

In case of complaint it is necessary to take the contact lenses off and suspend their use until the complaint has stopped. Damaged contact lenses must be thrown away. It is necessary to clean and disinfect the contact lenses whether complaint is tied to eyelash or a foreign body. Users must contact a specialist whether the complaint occurs again.

In case of under-treatment, some complaints can lead to serious disturbances, such as:
  • Infections – Although they are rare, infections occur because of dirty hands, incorrect treatment of the lenses, use of expired solutions. The most popular infection is conjunctivitis - the eyes burn, water and become flushed with purulent discharges. In such case a doctor should understand the reason of conjunctivitis and prescribe antibiotics whether the conjunctivitis is tied to a bacterial infection.
  • Ulceration of the cornea – Inflammation of the cornea along with loss of epithelium -it appears through intense sore eye, blurred vision, reddening, presence of muco-purulent discharges. A pharmacological treatment is needed to oppose this kind of inflammation, regardless of its reason.
  • Neovascularization – It occurs when the cornea does not get enough oxygen, often because of a too tight interaction of the contact lenses with the eyes. It makes the flow of tears more difficult, so that additional, growing blood vessels appear within the eye.
  • Iris inflammation – An non-infectious inflammation – reddening, photo-phobia tied to bright lights. Proper eye drops prescribed by an oculist are needed to bring relief.
