###Human: Suddenly, I am having double vision at both close and far objects. Do you have any idea? ###Assistant: Hello. The fact that your vision becomes better upon changing the position of the head or pulling your eyelid towards your ear proves that this is only related to your newly acquired age-related refraction. By reducing the area of the eye slit (changing the position of the head leads to the being covered more by the upper eyelid and reducing it manually by pulling your eyelid to the side), you reduce the refractive changes in your eye. The fact that the specs provide you with better vision while reading and relieves you of your main symptom is enough to make you feel calm towards this newly acquired physiological (it always starts after 40) change in vision. However, please refrain from using that correction to see distant objects because it is not designated for that distance, taking into consideration that you do not need it for distant objects, and might lead to headaches if you do. Otherwise, you should be good to go and start adapting to this newly acquired condition because from now on, every five years it is going to change and you will need more correction to correct that age-related deficit. Some additional recommendations would be to increase the size of the fonts on your devices to evade the necessity of using the specs every time you need to visualize your devices at a near distance. Also, lubrication of the eyes with artificial tears can also help maintain an absolute clarity during visual activities.
