Yes, expensive ones. A larger eye lens is typically found with eyepieces that have (a) a long eye relief, and (b) wide field of view.
Eye relief is the distance between the eye lens and your eyeball, which as you will be aware is painfully short with cheap eyepieces and those of older designs (orthoscopic, plossl, kellner).
Examples that provide long eye relief and are very comfortable to observe with include:
a. Vixen LV or NLV eyepieces, all have 20 mm relief and 50 degree field of view, sharp, moderate cost, they are small and lightweight. The LV's are obsolete and you'll have to find them secondhand, the NLV's are easily bought new.
b. Vixen LVW eyepieces, all have 20mm eye relief, 65 degree FoV, but much bigger, heavier and significantly more costly. In focal lengths down to 3.5mm.
c. cheap knock-offs of the LVW's (and inferior too) - Baader Hyperion, Orion Stratus...
d. TeleVue Panoptic, Radio, Nagler, Ethos... Wide field of view, big and heavy like the LVW's, and a lot more $ too.
Ultimately you really only need 3 eyepieces - low, medium and high power, maybe 4 at the outside.
