Can I use my glasses with these?

Yes, look for binoculars with 'long eye relief' (at least 16mm). These allow you to see the full image while wearing eyeglasses.

Do I really need my own pair if I'm with a guide?

Yes. While guides have high-end gear, they are using them to spot animals for the whole vehicle. Having your own pair allows you to track individual behavior without waiting for your turn.

Choosing the Right Binoculars for an African Safari

Stick to 8x42 binoculars for the best balance of brightness, field of view, and image stability. Avoid anything over 10x magnification, as the movement of a safari vehicle will make the image too shaky to focus on wildlife.

Select the correct magnification. Choose 8x magnification. While 10x sounds better, it narrows your field of view and magnifies the vibrations caused by a idling safari vehicle, making it difficult to track moving animals.
Prioritize lens diameter. Go for 42mm lenses. This is the 'gold standard' for safari use because it allows enough light in for early morning and late afternoon game drives when animals are most active and the light is low.
Check the field of view. Look for a wide field of view (at least 350-400 feet at 1,000 yards). A wider view makes it easier to locate a leopard in a tree or a bird in a bush once your guide points it out.
Ensure they are waterproof and fog-proof. Botswana is dusty and can be humid. Ensure the binoculars are O-ring sealed and nitrogen-purged to prevent internal fogging and protect them from fine Kalahari dust.
