Patient As Tennis Player, is using Vx.Comfort right now

RX

R: -5.25-0.75x105
L: -1.00-1.75x85

Add: +2.25

Does anyone can suggest which lenses go for? Is it Progressive Life AT suit for him or Vx.Panimic Much better?

Rigid ditance contacts to correct the anisikonia, Vx comfort, possibly photochromic with Uv and what ever other coatings patient desires.
You can't believe the distortion and image placement imballance as eye moves from central postion here. Playing tennis the patient is not just going to look down, the eye will diviate in all positions and each eye will see the ball: a: as different sizes. b: in a different place in each eye.
Brain will constantly be trying to decide which image to trust.

Could i reduce patient's add?THen let patient know this is just for sport use?

Hi tktien,
Try to prescribe distance only withy polaroid sunglasses, tel him to change back normal PAL after sport. He will fell more comfortable.

If he want PAL go for the Hoyalux iD because the PD change according to pt. They also have suntech which is similar to Transition.

:cheers:

The imballance problem isn't primarily in the add. It's the distance power that's the problem.. The patient is going to see two tennis balls except when he is looking through the dead center of the lens. The further away he looks, the further the balls will be apart.

Chip is dead on and being optimistic, Even when looking through the OC, the eyes will see 2 diffferent size images which will also effect depth perception.

If the contacts are not a option, I would do SV in a small frame to reduce prism in the peripheries and use the same BC in both lenses to reduce anisekonia.

Used free form Technology
it will help this case for anisometropia better than semi finish PALs.
