Question about myopia and blindness?

I think you will be just fine...you have moderate myopia and you are in your early 20's...if you have had it for 15 years and you are only at -5.00 now you can relax and rest ured as that is a normal thing (for myopia to progress between the ages of about 10 and 20 and then to stop). There are complications ociated with high myopia (over -8.00), but even that is not very common. To be blind you need a whole lot more minus than -5.00, I know someone who is -23 and they still have perfect corrected vision with contacts. So relax! It is a good idea though to have your eyes checked however because you say your pupils look dilated, but some people just naturally have larger pupils it could also be a side-effect of one of your medications for your seizure disorder. If you are still wearing contact lenses, you need to stop though as without having someone checking your eyes at least once a year whilst wearing contact lenses you could get infection and actually lose your sight that way. You don't say how you feel your vision is deteriorating. Are you battling to read things up close or is it seeing things in the distance? If it is up close that actually means your eyes have gotten better! If it is distance, it could just mean your specs need updating! Good luck!
