How many hours a day can you wear contact lenses?
Many people do not care about the wearing time of contact lenses, but they do not know that the so-called standardized use also includes the control of wearing time. It is important to know that the wearing time will directly relate to eye-related risk issues!
For the duration of wear, you can generally refer to the instructions on the contact lens packaging. However, due to differences in individual eye conditions, wearing environments, and visual requirements, it is usually not recommended to wear them for the full duration indicated. Generally, I suggest wearing contact lenses for no more than 8 hours a day, and for long-term use, it's best to limit it to within 6 hours, which helps maintain eye health.
Wearing contact lenses for too long can lead to many hazards. The primary issue is oxygen deprivation. The cornea relies heavily on air for its oxygen supply, but wearing contact lenses can result in insufficient oxygen levels, weakening the eye's resistance and affecting tear secretion. Additionally, oxygen deficiency can trigger more severe eye problems. Another concern is infection; prolonged wear allows bacteria and viruses to multiply easily within the eyes, leading to infections. Lastly, there are more serious eye conditions. Oxygen deficiency can cause excessive dryness on the surface of the eyeball, which over time can lead to dry eye syndrome or even more severe diseases. Many enthusiasts particularly enjoy wearing colored contact lenses, which have even poorer oxygen permeability, making them more prone to various issues.
When using contact lenses for the first time, it is quite common to experience some discomfort, which is a normal phenomenon and can be monitored. If the intense discomfort persists for more than five days without relief, it is advisable to stop immediately and seek help from an ophthalmologist. Whether you are a beginner or not, if symptoms such as redness, swelling, dryness, itching, photophobia, tearing, increased secretions, and severe blurred vision occur, it may indicate an infection. In such cases, reduce or stop wearing contact lenses and analyze the cause. If necessary, follow medical advice for treatment; do not use eye drops casually, as this can worsen the condition.
In order to relieve the pressure of contact lenses on the eyes, you can wear them alternately with glasses, because wearing glasses does not put too much burden on the eyes. The editor suggests that you wear contact lenses no more than five days a week and do a good job of cleaning and disinfection at the same time.
