Feeling blurred in the right eye after sleeping is usually caused by incomplete lid closure, conjunctivitis and pressure on the eyeball. In patients with incomplete lid closure, the upper and lower eyelids do not close completely when sleeping, leaving a gap, which leads to drying and damage of the corneal tissue exposed in the gap, affecting the transparency of the cornea, thus leading to blurred vision. Conjunctivitis patients sleep, eye secretions will be pooled in the conjunctival sac, or even covered in the corneal surface, will also affect the patient’s vision, resulting in the patient woke up to see the symptoms of blurred. If the patient puts his/her arm on his/her eye while sleeping, the pressure on the eye will lead to temporary deformation of the cornea, resulting in blurred vision after waking up, which can be recovered quickly. It is recommended that patients who experience blurred vision after waking up from sleep should consult a doctor promptly to assess their condition and follow the doctor’s instructions for treatment.
