Sorry, I was a bit busy with work hence the delay.
The reason why some days with the contacts are uncomfortable is that they induce a papillary conjuncivitis ( tiny papillae appear in the under surface of the conjunctiva after prolonged use for years). There could alsohave been associated dry eyes
whih is very common with contact lens wear. I guess a regular use of preservative free lubricating eye drop such as refresh tears or systane, 1 drop 4 times a day, should help.
I guess your left eye has good vision with the contact lens( 20/25) whereas the right has 20/30 with the glasses. Does not look like any myopia induced by a cataract in the right eye( -5.0 D myopia with cylinder would not have been due to a catarct). So I guess you can stop worrying about a cataract in the right eye at present.
Occasional floaters are common and are most often caused by posterior vitreous
detachment or PVD. Here is a brief note on PVD. .
In this condition the thick gel at the back of the eye( called vitreous) gets detached from its surrounding retina . This results in retinal traction which results in the symptom of flashes of light
and includes color distortion. Flashes of light may not be prominent in some individuals. Once the vitreous gets detached completely , it may form clumps or strands and cause symptom of floaters such as dark spots, cobweb or thread like strands in the visual field. More often it is not a serious issue and does not require any specific treatment. A routine retina examination needs to be done by an ophthalmologist just to check for the intactness of the retina and to look for any peripheral retinal tears or holes, which if found, can be sealed by lasers. The only concern is that of a remote possibility of a retinal tear extending into a frank retinal detachment
, which is characterised by symptoms of sudden increase of flashes or floaters and a curtain or veil falling in the field of vision. This requires urgent treatment by a retinal specialist. This is not a common feature and is more predisposed in myopic and diabetic individuals. You do not seem to be having any of these acute symptoms and you have already had an eye exam. PVD can occur suddenly at anytime and is a diagnosis of exclusion and does not show any signs as such on eye examination.If PVD is confirmed then there is nothing much to be done. It would be best to ignore the floaters after that. Some floaters tend to drift out of visual field too.
