Have been wearing contact lenses since I was 18. A few weeks ago my eyes became red and sore with a sort of burning sensation. I stopped wearing my lenses and took medicated eye drops. Eyes cleared up so after a few days started wearing the lenses again but the same thing happened- eyes became sore and were so red I couldn't go out in public without wearing sunglasses. Left the lenses out for a week and tried to wear them for an hour yesterday, but you guessed it the same thing happened again... Have now accepted defeated and bought a pair of glasses and have booked an appointment with my optician to check my eyes, though I'm pretty sure it's the contact lense they're rebelling against and not an infection. Why oh why after 15 years can I not wear the lenses. Never had a single problem with them before, so bloody annoying!
