I have to see a new eye doctor and they told me because i wear contacts i

[vacation chick]

have to go 3 days before the appt..? Without my contacts. Why do they want me to go 3 days without contacts? I wear my contacts all day and every day i havent had to wear my glasses in years. And with all my previous eye doctors ive never had to do that. Why would i have to go 3 days with only my glasses? My glasses are 2 prescriptions behind my contacts. Anyone know why ive never had to wear my glasses 3 days before an appointment and why?
