The blood that you observed on the sclera or the white part of the eye is called a subconjunctival hemorrhage
. There may be various causes for this and the ones that could apply to you are trauma due to the Hard contact lenses you use, chronic coughing, constipaton or lifting heavy weights that raises intraocular pressure
for a few seconds and can cause subconjunctival hemorrhage. Any rubbing of the eyes while the lenses are in can cause this condition. You have been asked to refrain from using contact lenses for a while and this maybe due to an allergic contact lens induced condition called giant papillary conjunctivitis
. This will reduce tolerance to lenses, leave you with itchy eyes and redness
and lenses that shift frequently in the eyes. If that is the case, steroid
drops and lubricating drops are started till the condition resolves. Lenses can be resumed after treatment but patients are encouraged to try soft lenses instead. If you have an eyelid infection
the tolerance to lenses also reduces and the infection is treated with steroid antibiotic combination ointment. The bleed you have experienced is probably due to your lenses and it would make sense to switch to more comfortable soft lenses if your refractive error
is corrected adequately .
