Ask an Eye Doctor and Get an Answer ASAP
Thank you for the question.
It would help to know your age as it would help to know if there has been accomodation in undilated state. Accomodation is known to increase the myopia and is abolished by using cycloplegic eye drops( dilating). Please get back to your ophthalmologist to know if you need a PMT or post mydriatic test which gives the subjective correction of the glasses. Myopia can increase every year until an individual has reached the age of 25 to 30 years. After that there is seldom an increase.
Thanks and best wishes
Thank you for the reply.
Spectacle correction needs to be given in 2 visits. The first visit is to dilate( in young individuals) and look for refractive error . In the second visit correction factors for the dilating drop and the distance at which test was performed are considered. Then subjective correction is given. You can get back to the ophthalmologist to verify and to ascertain the number again.
