Question 1

is it okay to use 2 glasses of different prescriptions?

Accepted Answer

Sure: Many of our patients cannot tolerate bifocals or have a need for computer glasses and wear multiple pairs - no harm done.

Question 2

can you tell me if i switch from glasses(prism lens) to contacts(different prescription) will that cause unusual discomfort?

Accepted Answer

Depends: If you have double vision when you don't wear your glasses with prism, then you will have it with contact lenses.  If double vision is not a problem for you, then contacts will likely work.

Question 3

axis values on my prescription glasses 2 years ago were r:20 l:160. new glasses made recently have r:110 l:60. is such a strong change possible, or could one of the two be incorrect? how is it possible that i can still see well with both glasses?

Accepted Answer

Optometrist: It may help to talk to your optometrist who may be able to resolve the matter. If your vision is okay, it may not be worth worrying about.
Have a healthy diet, exercise 30 minutes/day, drink plenty of water daily so your urine is mostly colorless, have safe sex, no tobacco alcohol weed or street drugs. For nutrition: http://www.choosemyplate.gov/.
Wish you good health!

Question 4

why is my contact lens and glasses prescription different?

Accepted Answer

Distance from cornea: Contacts sit directly on the cornea so their magnification power is different than lenses in glasses that are in front of the cornea.

Question 5

are contact lenses a different prescription than my glasses?

Accepted Answer

Yes: Contact lens also has size of size of cornea, in addition to power.  That's why contact lens have to be 'fitted'.    The power may differ also, if the myopia is significant.

Question 6

my contact lens prescription is significantly different from my glasses prescription. is this normal?

Accepted Answer

Yes: It is due to a differing vertex distance or where the corrective lens is placed in relationship to the corneal surface - this is normal.

Question 7

what's causing my headache? happens wether i wear prescription glasses or sunglasses (different sizes). i never had this problem before until a few weeks ago. i can only wear them for short time and once i take them off i feel immediate relief?

Accepted Answer

: The headaches might be related to the correction of your lenses.
If they cause you to squint a lot they can be the problem.
A visit to your optomitrist is in order to evaluate your prescription.

Question 8

an eye examination by od showed -2.00 left eye for glasses. but, it was -3.25 two yrs. earlier and -3.50 three yrs. ago. prescription not made yet. re-exam?

Accepted Answer

I would : Re-exam sounds like a good idea. When we see this kind of fluctuation we also consider the possibility of diabetes.

Question 9

headache and tension under eyebrows since working from home for two months. got prescription reading glasses 4weeks ago. no improvement. changed office lighting and layout to avoid glare and bad light. checked ergonomics too?

Accepted Answer

Headaches: I agree with Dr. Barnard.  This might be a tension headache. However, there really isn't enough information to know. If this has been going on for a couple of months, it would be worth an assessment by your PCM. Take care.

Question 10

i am experiencing blurry vision.my right eye has been blurry for the past two to three years and i have prescription glasses multifocals.for the past few days the vision on my left eye is more blurry and my right eye is also blurry?

Accepted Answer

Check for diabetes: Diabetes and blood sugar levels can affect vision acutely. Check your blood sugar and followup with your primary care physician or opthalmologist to check your vision.
