Contact lenses vs glasses

[Lockhouse]

I'm short sighted, I can't see close up wearing either glasses or contacts. Normally I wear contacts as my monitor at work is a couple of feet away which is OK, but tend to wear glasses at home so I can lift them up to see things up close or to read. When I read on the train home it's easier to do it with one eye shut....and there rests the case for the defence M'lud...

You know you can get bi- and vari- focal contact lenses?

These are more expensive than contact lenses for straight myopia and presbyopia but if you having to go through that hassle I would mention it to your optician. I had to push an optician into giving me the correct prescription for my contact lenses in the past when I changed opticians as they often try and get you on to the cheapest lenses.

Cheers - I will see what he says at me next eye test.

You're doing well if you can read comfortably in a full contact lens prescription. Just how far away do you push your monitor

The expected maximum and minimum amplitudes of accommodation for a corrected patient of a given age can be determined using Hofstetter's formulas: Expected amplitude (D) = 18.5 - 0.3 x (age in years), Maximum amplitude (D) = 25 - 0.4 x (age in years), Minimum amplitude (D) = 15 - 0.25 x (age in years).
Presbyopia - Wikipedia, the free encyclopedia

E.g. expected amplitude is 18.5 - 0.3 * 45 = 5 dioptres for a 45 years old. Min & max range is 3.75 to 7 dioptres.
