TTL

Our TTL glasses are custom built as they include the lenses from your ophthalmic prescription in both the external support lenses and inside the spotting scope eyepieces, the tilt angle of the telescopes, the working distance (focusing of the telescopes) and the centring of the latter according to the user’s inter-pupil distance, all in order to obtain the most ergonomic possible magnifying glasses.
TTL is an English acronym to indicate Through The Lens which allows you to bring the eyepiece as close as possible to the user’s eye, thus obtaining a greater field of view.
