I've compared the views recently between a properly optically polished pair of lenses from the optometrist and a $5 cheapy from the Newsagent. The cheapies have such ripply surfaces you can see the roughness just by looking at a light at grazing incidence. The cheapies are not polished properly and the material quality is poor so the view is hazy and nowhere near the quality and optical contrast of properly polished CR39 lenses, aside form the eye strain issues of wearing glasses that are not correctly configured for your near -focus inter-pupilary distance.
Sure the cheapies will help you to read the newspaper for $5, but why would you compromise your vision for the sake of a few dollars. Fortunately for the makers of this optical rubbish, so many people think that they are `good enough' and continue to `self medicate' with pairs of cheap glasses instead of having proper eye care.
The fact is that the inside of your eye is the best window to so many medical conditions that threaten the rest of your well being as you age , including cancer, claucoma and high blood pressure just to name a few. Anyone over 50 should have a yearly eye examination, and give their eyes the best optical aid they can afford.
No I'm not an optometrist, but I saw a member of my family die due to ailmaents that would have been picked up with ergular eye examination.
