Hello, I am a glasses user with the right size: -3.75 u0026amp; cyl -1,25 while for left size: -5,25 u0026amp; cyl -0,5. I used to use softelns for an event with a recommendation of a size greater than 0.25 than the normal size (co: right to -4) because to match the cylindrical (the contact lens I used had no cylindrical). Even so, I am not comfortable using it. Right now I need to use contact lenses again to do an activity, but I am confused in choosing the size. Is it better if I order the same size as the minus of my eye or exceeds 0.25 of the prescription? Thank you

Good evening, thanks for asking at HealthReplies.com. For contact lens use, in theory it's basically the same as glasses, that the best size is the size that suits your eye's needs. It's just that measurements on the glasses can not be simply transferred to contact lens measurements because of the difference in distance between the contact lens and the lens of the glasses with the surface of the eye.


In glasses, there is a distance of a few inches between the lens and the surface of the eye, while in contact lenses, the surface of the lens is attached to the surface of the eye. This is what causes the calculation of its size can not be exactly the same, and for that, you should check yourself to the eye doctor.


Then, the same with glasses, although in theory the best size is the right size, in fact sometimes the right size is uncomfortable to use. Not infrequently the lens used with a smaller size than it should be even more comfortable for the user. In this case, comfort comes first before accuracy.


So regarding your question, it would be better if you determine yourself which is the highest size most comfortable for you. If it already seems too bright or too heavy, it means it's too tall for you. Lower it, and keep trying until you feel comfortable to use for a long time and also use it to walk and look in various directions. Don't assume that your eyes will adapt to that discomfort. If you are still doubtful or confused, consult your eye doctor. So, hopefully answering your question.
