Is 8 mm eye relief a problem?
I posted a question about the Orion Little Giant binocs and one of the
responses indicated something I hadn't noticed in the ad...the eye relief is 8 mm. Is this a problem? I don't wear glasses. Does that short eye relief mean I'd have to have my eye sockets buried into the eye cups? thanks for answers...it's a big expenditure for me and I don't want to buy a hassle.

Taking-in the entire FOV with insufficient ER can be uncomfortable on the eye sockets. Another consideration is the additional ER needed with the eyeguards extended. Longer ER also helps avoid contact between their eyelashes and the eyepieces which can smear the lenses with residual oils/dirt. |

Another consideration is the additional ER needed with the eyeguards extended. Longer ER also helps avoid contact between one's eyelashes and the eyepieces which can smear the lenses with residual oils/dirt. It should be added that there is such a thing as 'extraneous' eye-relief. While eyeglass wearers are very content with 20mm of ER (15-18mms being a tolerable minimum), those without glasses may experience a field 'blackout' when their eye placement is too close (extending the eyeguards will usually compensate for this). Generous eye-relief, however, is certainly better than not having enough. |
