Would CR-39 be a mistake?

[llal98@aol.com]

Hi all,

Would CR-39 be too heavy or thick in my prescription - in a plastic frame?

+1.00 -.75 x 90 Add 250
+1.00 -.50 x 105 Add 250

Thanks for sharing your expertise and opinions!

nope, it will be fine, unless it is bigger than a 60 eye, and assuming you want progressives

Thank you - that's great - and yes, progressives, smaller than 60.

My husband's rx is a lot like yours, except his is a +.50 in the distance with about the same cylinder and add. So his are slightly weaker. I have always gotten his in standard plastic before but the new lenses he got don't come in standard plastic yet.

His new glasses are poly and he commented to me how much he likes the thinner and lighter lenses. They are very small, only a 48 eye size but it does make a difference. I am a little surprised but they are noticably lighter and thinner.

Given the fairly low rx and the use of your small plastic frame, you would absolutley be fine in a cr39 lens.

Thanks Happylady and Shellrob. Even though poly would be even thinner, I'd rather go with the plastic as long as they're not too thick, just because I've had better luck with plastic in the past.

CR39 is you best choice for a clear and crisp vision in that prescrition.

Actually, any material would be "clear and sharp" in that prescription. The physical advantages of other materials in weight and thinness would probably be measurable but not perceptable to the user.

Depending upon the cost difference, polycarbonate could be an option as it does offer 99%+ UV protection (I believe a necessary precaution) while being slightly thinner and lighter. If you choose CR-39, do consider adding UV protection. There is just too much evidence of damage to the eye from UV to ignore this low cost addition. Or Transitions would be another option as it blocks UV and changes darkness to adapt to bright lite; that's my personal lens of choice for everyday use.
