Diplopia in the eyes of patients is usually not the worst in the morning, depending on the patient’s condition. Diplopia can be categorized as monocular diplopia or binocular diplopia, where monocular diplopia is a condition where one eye can have double vision even when viewed alone. Monocular diplopia is usually caused by a subluxation of the lens, astigmatism, etc., and is usually just as severe at any time of the day. Binocular diplopia can be caused by a variety of reasons, including ocular myopia, which usually has milder symptoms when you wake up in the morning and more severe symptoms at night. Paralytic strabismus, restrictive strabismus and other causes are usually equally severe at any time of the day. It is recommended that patients with eye discomfort seek medical attention to evaluate their condition and follow their doctor’s instructions.
