2.Over-extended wear- wear more than 14 hours

3.Wearing contact lens in polluted environment

- Dust, smoke can contribute to lens contamination

4.Incomplete blinking- can cause contact lens drying because

reduction of tear exchange between lens and cornea

- recommended blinking exercise

5.Use of drugs- antihistamine, diuretics reduce tear production

3.Smoking - Lipid layer of tear film deteriorates due to

smoking

4.Wear contact lens without professional control

- Especially those who buy through internet. No aftercare
