Not sure about the lashes but you can’t have any nails on or nail varnish. They need to see the colour of your nails because if they turned blue it would be an indicator that the oxygen levels in your body have dropped and then they can react x
I rang the clinic up and the lady that works there said she was pretty sure I can keep them on
She saw a girl with them on this week who had surgery. She’s going to get back to me x
I had nail varnish on fingers and toes only and it was ok. They prefer you not to wear gel or false nails as it can affect the reading (false reading)on the observation machines (the little device they clip onto your finger to read oxygen saturation levels and heart rate). As for lashes sometimes they use tape to keep eye lids closed for safety reasons.
