Can Babies Open Their Eyes In The ᴡᴏᴍʙ?

Vision is the last sense your baby develops, which helps explain why her eyesight is so fuzzy as a newborn (at birth, your baby can only see about 8 to 12 inches in front of her).

From around 27-28 weeks ɢᴇsᴛᴀᴛɪᴏɴ babies do open their eyes. It can be seen during a  4d baby sᴄᴀɴ and we are able to see babies moving their eyes and looking around. It is said, that they are able to see dark, light and movement, but they aren’t yet able to focus properly quite yet.

Your unborn baby’s eyelids remain closed until you’re about 28 weeks pregnant, which allows the retinas to fully develop. After that time, her eyes open and even begin to blink. Here’s a fun fact: As soon as their eyes open in the ᴡᴏᴍʙ, twin babies can find each other – and will touch each other’s faces or hold hands!

Just as the ᴡᴏᴍʙ isn’t completely quiet (your baby can hear sounds like your voice, ʜᴇᴀʀᴛʙᴇᴀᴛ, ᴀɴᴅ ᴛᴜᴍᴍʏ growling), it isn’t totally dark, either. As early as week 18 – when her eyes are still closed – your baby’s retinas can detect a small amount of light filtering through if you’re out basking in the bright sun. By week 33, your baby can start seeing dim shapes because her pupils are able to constrict and dilate.”  Karin A. Bilich

With 4D sᴄᴀɴs true colour is not picked up, so you wouldn’t be able to see the colour of your baby’s eye or the colour of their hair, this is down to ɢᴇɴᴇᴛɪᴄs so you could take an educated guess, but there are always surprises. The colour that you do see in a 4D sᴄᴀɴ is created by the software which imitates sᴋɪɴ ᴄᴏʟᴏᴜʀ.



4D sᴄᴀɴs work by collecting echoes that are bouncing off different structures in the case of 4D sᴄᴀɴs then the echoes that are collected are the ones bouncing back at skin level. You may notice that any echoes that are not returned show on the screen as black. Clear Fʟᴜɪᴅ and gas do not produce echoes which is why you will often see a black area where ever Fʟᴜɪᴅ is present for example amniotic Fʟᴜɪᴅ around the baby.

The eyes contain quite a lot of Fʟᴜɪᴅ, therefore, strong echoes are not always sent back which means that when you do see your baby opening it’s eyes during a 4D sᴄᴀɴ then the iris is not seen clearly and the eyes it can show as quite dark, but this isn’t what is really looks like. If the baby has it’s eyes wide open sometimes, you can see slight differences of the eyes various surfaces.
