Contact lenses are a popular way to correct vision and improve visual comfort in people with vision problems such as myopia, hyperopia and other corneal diseases. However, using contact lenses may cause some side effects and health problems that must be taken into consideration. In this scientific article, we will take a look at some of the potential harms of using contact lenses.

1. Bacterial and viral infections: Contact lens users may be exposed to the risk of eye infections, such as keratitis, as a result of contamination or poor hygiene during insertion or removal of lenses. Sediment buildup or dehydration may also increase the risk of infection.

2. Dry eyes: Contact lenses can reduce the flow of oxygen to the eye and the proper distribution of tears, increasing the risk of dry eyes. This can cause a feeling of dryness, itching, redness, and visual fatigue.

3. Corneal abrasion: If the correct usage instructions are not followed or lenses are used for long periods, corneal surface abrasion may occur. This can lead to worsening vision and increased vision problems in the long term.

4. Allergies and sensitivity: Some people suffer from an allergy to contact lens materials or to the solutions used to clean them, which leads to irritation, redness, and swelling in the eye.

5. New blood vessels form in the cornea: In rare cases, contact lenses can cause new blood vessels to form in the cornea, affecting vision and requiring surgical treatment.

6. High intraocular pressure: Some studies have indicated that some types of contact lenses can increase intraocular pressure, which in some cases can lead to the development of glaucoma.

7. Problems with photosensitivity: Some people who use contact lenses may experience problems with photosensitivity, which affects their ability to tolerate bright light.

In addition to what was mentioned above, misuse of contact lenses can lead to problems with vision and general eye health in the long term. Therefore, contact lens users should follow proper instructions for use and hygiene, and have regular eye examinations to ensure there are no ongoing health problems. If any unusual symptoms appear, the individual should consult a specialist doctor to provide appropriate care and advice.
