CARE AFTER LASIK. When it gets cure?

Hi. I undergone lasik procedure on oct 14 two months got over. They prescribed GENTEAL Gel at night after 10 days of the procedure i just forgot it and start using it after 30 days only. But i use lubrex lubricant whole day. I want to know is there any problem becoz i missed to apply the gel for 20 days?. For second month they prescribed IREWET lubricant. They told me that after two months you can use IREWET or LUBREX DS drops as lubricant of your choice. I want to know IREWET/ LUBUREX DS which one is best as a lubricant? Due to work i startes using laptop for more than 6 hours what i should do to protect my eyes. I ask about to use blue ray glasses but doctor told me to avoid it. What should I do? If i go in the sun my eye got little sensitive and vision got blur i use polarised sun glasses when the sensitivity cures and is it compulsory to use sun glasses? Dur to high power of -8 with cyl -2.25 even after two months of procedure my vision is blur when it gets cure?
