It definitely means higher maintenance what with a kid like Wyng who always tests the durability of glasses. He hardly takes care of them. After only two years of being diagnosed with myopic, he has ruined 3 pairs of glasses. He was wearing the fourth pair of glasses with no damages until a few days ago, unfortunately, we had to give him a new set of lenses as his power (for myopia) has increased by about 100 for both eyes. His fourth pair of glasses was only a few months old, less than six! Thankfully, he manages to maintain his astigmatism at the same level as last year.
Left with no choice, we had his lenses changed whilst still retaining the old frames. On top of this, we made another pair of spare glasses for him as a contingency for 'accident', just in case. At a power of 200 and 175, this can be blinding enough for this avid reader.
Having an increase in his myopia just means that this boy has been writing or reading at a distance with his eyes too close to his books. Sigh.. I have caught him a zillion times with his chin on the desk whilst doing his homework. This does not include the time he spends alone in his room alone for his bedtime stories or reading during other times of the day.
I'm glad that his astigmatism doesn't increase. It shouldn't be as he hardly has access to the computer and television watching is mostly at a 'safe' distance.
