QUOTE(jialat @ Nov 8 2010, 11:58 AM) hi, any power above -4.00 will need a reduction of -0.25, while power above -6.00 need reduction of -0.50 and the higher the power, the more reduction will be needed according to calculation. of course age does play a role too, if u are close to 40 year old, then a slightly more reduction will be beneficial for ur near work. the reason why they decrease by .5 because they said if glasses is far away from ur eyes compared to contact lenses. is it true? if u are below 40 year old, a 0.25 reduction is adequate. thus, the power u need is right -5.00, left -4.00 for a clearer vision. thanks hi, its best to use silicone hydrogel lens like air optix and acuvue oasys for long hours use in air conditioned room. pls pm me ur eye power and i will recommend accordingly. thanks if i wanna change to -5.00 and -4.00 for free ofcourse can right? because it is not my fault. right??? |
