The other option is a proper set of eye exercises done daily to reduce and in some cases eliminate the problem. NASA does this and it seems to work nicely (notice even the elderly space cowboys don't seem to wear glasses). Try those methods for about 6 weeks first. Unfortunately to do it via the convenience of home will cost some money but if you skip the exercises and start on the path of using glasses and contacts or RKT procedures you may be screwed.
