For example, at 45 years old, the presbyopia is +1.50D (150 degrees). By the age of 50, whether you wear a mirror or not, the presbyopia will increase to +2.00D (200 degrees). Strong support without wearing reading glasses, ciliary muscle exhaustion can not be adjusted, will certainly increase reading difficulties, resulting in dizziness and other symptoms, affecting life and work.
