π€ I got new glasses! π These are my first colorful glasses since 8th grade and they make me so happy! To share the joy, I have some fun glasses facts for both eye doctors and non eye oriented folks. (some=good study tips for the ophtho oral boards!)β β β β β β β β β

ποΈ you can tell if i am near or far sighted (aka myopic or hyperopic) just from this picture. What's your guess?β β β β β β β β β

π€ For people with very high prescriptions, this frame size is borderline too big. Do you know why? β β β β β β β β β

π§ What are progressive lenses? β β β β β β β β β
(glasses that allow you to both see distance and read up close - lens changes gradually without the line seen in bifocals. both progressives and bifocals are for presbyopia, an age related change that affects all of us, starting around age 40 (π!). The change decreases the ability to read up close without glasses and it's coming for you, so enjoy reading this IG post while you can!), π§π§ With progressives, is it better to have big or little frames? β β β β β β β β β

ποΈ I'm near sighted or myopic. You can see that my lenses make my eyes/face smaller. On my prescription, the first number would be '-'. (Far sighted or hyperopic lenses enlarge eyes and are a '+')β β β β β β β β β

π€ Really high prescriptions have thick lenses that get thicker as you go farther from the center (think "coke bottle" glasses). They get heavy and uncomfortable when frames are very large. β β β β β β β β β

π§ Progressive lenses are best in a large frame to allow plenty of room for the full range lens thickness. In a tiny frame, there may not be enough space to get from the size distance lens to the full reading lens.
