Glasses are a scam. For most people if you’re visions slowly deteriorating and you return to the optometrist to get a stronger lense, it’s bc your eyeball lense is stiffening due to lack of being squished and stretched. It’s a bad cycle.

I was refused entry into the AF as a pilot, did 30mins eye exercises everyday for 6 months as a 17yo. Increased acuity, got in, the rest is history. The point is, get a break from the screen - even 2 mins a day of this:

- close one eye, hold your thumb 6in in front of your eye, focus on a distant (>20ft) object, focus back on your thumb concentrate on the detail. Adjust your thumb distance so your eye is mildly straining. Swap focus near and far 20 reps.

- swap eyes do the same. Done.

As with all exercise don’t kill your self, just make it a habit and you’ll delay becoming dependent on the specs.
