OkieGal,
Over wear of your contact lenses would not change your prescription

That is something which naturally happens to all of us over time. A yearly examination is recommended with your eye care professional and in fact it is NORMAL to experience an annual change. It sounds to me like you need to book yourself an appointment. You have what is considered a moderate prescription. Fortunately these days, we have polycarbonate and high-index lens materials which reduce thickness and weight by about 50% compared to standard plastic. These materials will suite your prescription just fine

If you are near sighted, the smaller the frame the better! The thinnest portion of a minus power lens blank is the center, meaning, the larger the frame you choose the thicker your lenses will be! (yuck!) Other options I will reccomend for you are "rolling" of the lens edges (not polishing, as this will creat shine, thus drawing attention to the lens edge) and Anti-Reflective coating which reduces glare for computer usage, work under fluorescent lighting, and for night driving. Prolonged contact lens over wear is very unhealthy for your eyes and you will suffer the consequences later. Depending on the severity of your overuse, blood vessels may have grown into your cornea, which may obstruct vision. Your best bet is to have an exam done, receive a new prescription, and put the money together to get a GOOD pair of glasses with the options I recommended above. Your eyes will appreciate the difference and the oxygen!
