I loved this video! It helped me so much. I am grateful for finding a video like this because it only took me a few tries to get my contact lenses out with long nails by using this technique. Thank you so much!
After trying to remove the lenses for hours, I was afraid I was going to have to ask a dr to remove it for me hahaha but thanks to this video I got the hang of it on the 3rd try omg thank you so much!!!!
if we apply the rule LARS ,if the marks are rotated left do I have to add ,then in the example was 180 degree, marks rotate left then the axes should be 170. i am right ? thank you
Dear Alba, Thank you for your question. The LARS pneumonic is useful, but I think it is always worth keeping in mind what is happening to the lens on the eye. With a trial lens that rotates, we must the assume that our prescription lens will behave in the same manner, whether that be due to lid pressure or eye shape - the result will be the same. So if we have a lens that rotates 10 degrees left (clockwise), then we presume that our finished lens is going to do the same. If we were to order a lens with axis 180, then once the rotation takes place, the effect will be that our cylinder axis now lies along 170. In order to anticipate this, we must order a lens with axis 10, so that when our rotation occurs, the cylinder axis now aligns with the desired correction - 180. Using LARS - Left Add Right Subtract - we take the 180 (O) and add 10 to give 10. I think the problem here is that you try to read 180 as 180. If you consider it to be zero or merely horizontal, then imagine the rotation taking place it will probably make more sense. I hope this helps. - Martin
