The story of how Tech got his goggles:

The batch woke up as useful one morning, but as he woke up Tech noticed his eyes seemed to have trouble adjusting.
Rubbing his eyes his vision evantually cleared although longer than it usually took.

Getting up and changing his clothes his vision still felt slightly blurred.
"Tech, is everything alright?" Crosshair asked coming over.
"Yes Crosshair, why do you ask?" Tech asked.
"Your shirt is on back to front." Crosshair said holding back a grin.
Tech saw and blushed in embarrassment.
"Ah, so it is." He said.

Crosshair quickly helped him fix his shirt and the two ran off to join the others for breakfast.
"You sure you're alright?" Crosshair asked as the two got into the mess and went to grab some food.
"Yes I'm fine, must have simply been waking up." Tech said.
Crosshair nodded although he wasn't fully convinced.

Throughout the day Tech struggled with his regular training exercises, for some reason his eyes just couldn't seem to focus on what he was doing, his vision continuously becoming blurred which was irritating when he was in the middle of a task and he suddenly couldn't see what he was doing, having to constantly rub his eyes to adjust his vision was annoying.

That night Tech grabbed his pajamas and went into the bathroom to change.
"Tech!" A voice yelled.
Tech quickly rubbed his eyes and saw Cobalt in front of him wearing just his pajama shirt and underwear, his pajama bottoms were on his hand and he was clearly in the middle of changing.
"Sorry Cobalt." Tech squeaked embarrassed and quickly left the bathroom.

After getting changed Cobalt left the bathroom and went over to Tech.
"What was that about, didn't you see me go in?" Cobalt asked irritated and embarrassed, but mostly confused.
"No, I'm sorry Cobalt." Tech said looking at his big brother embarrassed.
"It's fine, but are you sure you're okay, you've been struggling all day, Cross said you were even struggling to get dressed this morning?" Cobalt asked.
"I'm sure I'm fine, must just be a bad day." Tech said.
"If you're sure." Cobalt nodded, not fully convinced.

Over the next couple of days Tech continued having problems with his eyes, his vision seemed to flicker in and out of focus.
The other batchers told 99 about this who soon had his own suspicions on what was happening.

"Tech, do you need glasses?" 99 asked one night as he tucked Tech into bed.
"What do you mean bluir?" Tech asked confused.
"The others told me what's been going on these last couple of days, I think you might need them to help your eyes." 99 said.
Tech thought about this for a moment before humming in agreement.
"I think that may be the most logical conclusion." Tech nodded.
"Right, I'll see what I can do, goodnight Vodi'ka." 99 said tucking Tech into the blankets.
"Goodnight bluir." Tech yawned before succumbing to the pull of sleep.

The next morning Tech groggily woke up although he quickly forgot his exhaustion when he saw something sitting on the small table next to his bunk.
To his surprise they were a pair of goggles, much like ones he had seen some of the other scientists wear.
Putting them on Tech was surprised to find his vision was clearer than it been in days.

"How are they Vodika?" 99 asked from where he was standing in the doorway.
"They're great...thank you bluir." Tech said going over to 99 and giving him one of his very rare hugs.
"Its okay Vodi'ka, anytime." 99 said smiling and patting Tech's head gently.
