Answer 1

A lens change results in different off-center distortion.  If lines that used to seem straight now seem a bit curved from the higher power, you will adapt rather quickly and lose these sensations after a week or so (unless you switch between glasses and contact lenses).  These distortions are caused by lens power and base curve changes.  When prescriptions change, the optician sometimes has to adjust the base curve to balance lens asthetics (thickness, reflections) with function (optical properties).  For base curve changes, it's best to try to adapt rather than go back to the previous base curve since, if you require a stronger power again in the future, the change will be even bigger.

Did you change lens material for these new glasses to either a polycarbonate or hi-index material for a thinner lens?  These materials (especially polycarbonate) have poor chromatic abberation ("abbe") properties which result in edges showing a red/blue fringing when viewed off-center.  Many people are sensitive to this.  If you're seeing colors, you may need to work with your optician to find a more appropriate lens material.  Unfortunately, many opticians don't disclose this negative property of the higher-index lenses-- only the "thin" aspect.  Most people also get used to these "rainbows" as well and subconsciously learn to look through the center of the lens, although it is very noticeable at first.

Your eyes are having to focus a little harder to read due to the stronger lens power.  You can probably "feel" the muscles working harder, but be sure to differentiate this from a "pain" feeling.  If the pain is "around" the eye, then it's likely the muscles getting a workout.

If you're experiencing headaches after a week or so, then you'll want to have the fit checked.  Visit sooner if there's something obvious such as the frame not sitting level, tilted either up/down or left/right, or the temples pinching your head.

Answer 2

It is all normal, unless you are feeling ill or are in pain.  Also, this shouldn't be lasting much longer than a few days up to a week. Things should be normal again soon; your eyes just need some time to adjust. It happens to almost everyone.

Take care.

Edit: The fitting issue could be true. I'd still wait about a week and see if things clear up, and if still not, suspect a fitting problem.

Answer 3

Yeah, I got new glasses too. You can feel heaviness because your brain and eyes recognise the new glasses, so you always know they are there. I am not sure about the blurriness. Headaches are regular. I get some headaches when I put my new glasses on. Your doctor is right. Your eyes are just adjusting to the new glasses. Is this your first time switching glasses? This happens all the time to me because I have multiple glasses. After you wear them alot, you won't even know they're there, like when you used to wear your old ones. If you are aving severe headaches, or something like that, talk to your doctor again.

Answer 4

if your vision is blurry when you look thru the side of your lens, to me, sounds like a fitting issue. sometimes when you have new lenses made, even if there is no prescription change, and the place that you go gives you a lens that has more (or less) curve to it, you will get that effect.

i would take your old glasses and compare them to the new ones. if there is any difference in the curvature of the lenses, i would take them new ones back and see if they can adjust them to match the old ones.

hope this helps out. good luck

Answer 5

It could be just adjusting to the new lenses. However, if they are fitted wrong, they can cause lasting problems. The thinnest point of each lens should be directly in front of the pupil of you eye. If they are not, they will cause you eyes to pull.
