Should i be concerned if my son is albino 4 years old due to albinism eye sight weak and constant left right eyes movement is any cure?

Yes: Hopefully your son is seeing a pediatric ophthalmologist on a regular basis. The blindness associated with albinism is not curable and you will need support raising a blind child. The eye movement is called nystagmus and is expected in a blind child.

Kids with nystagmus: adapt to it. Ask his pediatrician to determine his type of albinism hy Chromosomal Microarray, then see a geneticist, pediatric ophthalmologist, audiologist, developmental/behavioral pediatrician & other specialists depending on his genetic mutations. Call Child Find of your local school district for developmental assessment & enrollment in Early Childhood Specisl Education. Resources below.
