Unilateral high myopia

[BigGrumpyBadger]

DD (10 months) has just been diagnosed with severe short sightedness in one eye and her glasses are now on order :(

The eye specialists at the hospital said that such early myopia tends to actually get worse, has anyone had experience of this - did it get better? worse?

My dd has the opposite she has hypermetropia her prescription is +5 both eyes.

Hasn't got any better but no worse. She like your dd got her first pair of glasses before turning one. She is 6 now

It's quite unusual to have a high prescription in one eye only. Is the eye otherwise healthy? It can sometimes occur after an infection (such as measles). It can also be just one of those things.
Myopia does tend to get slightly worse over time, but your daughter can probably have just one contact lens in that eye as she gets older.
She'll need glasses and probably a bit of patching on the good eye to encourage the weaker eye to work harder.
