How often does the eye blink a year?
According to optometrists, the human eye blinks an average of 4,200,000 times a year which corresponds to approximately 12,000 times per day!
But why do we blink?
Blinking is an essential function that helps the eye remove irritants from its surface and to also spread tears.
Blinking also helps keep the eyes free of dust and re-hydrates the cornea which is especially important in hot and humid weather such as in the United Arab Emirates, Saudi Arabia, Qatar and across the GCC.
Blinking can be increased for several reasons: tiredness, medications, diseases or illnesses, and eye injury.
Blinking And Contact Lenses
If you are a contact lens wearer, then wearing lenses can increase blinking if your eye is finding the lenses uncomfortable. If your contact lenses have a rip or a tear, this will rapidly increase your blinking as the eye tries to protect itself. In these cases, lenses should be removed and replaced by a new lens. You will also notice increased blinking with contact lenses if you wear them for a long period. How long you should wear contact lenses for varies on the specific lens and your eye type, but it is generally advised to wear them up to 8-12 hours a day.
The water content in contact lenses also affects your blinking. If you suffer from dry eyes or live in a hot and humid climate, daily contact lenses are often recommended by eye doctors as generally these have higher water content and allow more oxygen to pass to the eye.
Blinking And Colored Contact Lenses
Colored contact lenses follow the same rule as regular contact lenses. If you notice discomfort and blinking is increased, then this is a good sign that you should remove your contact lenses and allow your eyes to recover.
