There are two possible causes for blurred eyes in bed. The first reason may be that when you went to bed the night before, you used your cell phone or computer more and went to bed later, which caused eye fatigue, adjustment spasm, and adjustment lag, resulting in the adjustment function not fully recovered when you wake up in the morning, so you may have blurred vision when you switch between looking at the distance or looking at the near. In this case, the blurred vision is caused by the lack of relaxation when looking at the distance and the possible adjustment lag when looking at the near. The second reason is that the tear film is unstable during the early morning, which may be caused by dry eye or low tear production. The tear film is mainly the membrane formed by tears spread horizontally on the surface of the eye, this membrane is to help see things clearly, so if it is unstable it is easy to see things will appear blurred. Generally the most common causes are these two, can be based on their own situation to carry out the corresponding relief way.
