Do you often find your vision suddenly blurring and then clearing up again? That sensation where everything turns hazy as if behind a wall of fog, only to sharpen when you blink. If you brushed it off as mere fatigue, you might be overlooking an alert sent by your eyes.

Do you wake up dreading the morning stiffness, blinking all day long at a gritty feeling like grains of sand? Are you brushing it off thinking, 'It is just because I am tired'? To be frank, this signal from your eyes is something you should not take lightly.

Do you spend your entire day looking at smartphone or computer screens? By the end of the workday, have your eyes felt dry and dim, making text look blurry, or leaving you with a throbbing headache? That may not just be simple tiredness, but a serious warning sign from your eyes.
