I have been wearing contacts for 5 years.
Last week, the eye doctor at Specsavers said my new make of contacts had damaged my cornea a bit, and I need to wear my glasses for a week so it can go back to normal - and I'll change the make of my contacts as well.
I bloody hate every minute of it. They keep falling off my nose, they're under my prescription anyway since, as I only wear them before going to bed and before getting ready in the morning, I never bothered to have new ones made, they keep getting dirty, I look like a geek in them... I could go on ranting for ever. Can't wait for the appointment on Wednesday, and he'd better tell me I can wear contacts again.
Contacts are a gift from God, my friend.
