Pampering: 

• Starbucks’s VIA ready brew individual instant coffee packets–regular or decaf in 3, 12. or 50 packs for coffee lovers. My Dad would find them pricey–Probably wouldn’t buy them for himself. (Costco used to carry them.)
• Keurig Coffee Maker and coffee pods–a year-round, expensive–a gift my dad would never have bought for himself–a family-get-together-to-give gift perhaps. Coffee lovers, young and old love it and the coffee pods that can be delivered monthly.
• A mug (perhaps with a family photo?) to microwave the coffee in.
• Good bottle of wine
• Wine refrigerator 
• His favorite microbrew beer (a case?)
• Massage
• Professional shave
• Manicure/Pedicure
• An easy-care plant–decorative and life-affirming
• What about that Father’s Day cake?

Vision: we know vision changes with age; these gifts can enhance

• Large print books (for those who still like the feel of a book)
• An electronic book. Because the font can be enlarged–I hear it’s a Godsend. The background color can also make a difference so check this out with someone knowledgeable.
• A Verilux lamp can be especially helpful for those with vision issues. Two people I know (one with advanced macular degeneration) have the “Original Natural Spectrum” floor model. They say the light bulb adds clarity and the gooseneck directs the light where it does the most good for reading or doing desk work.
• The mini-maglite, small flashlights that give great light in dark places.                             
• Pocket magnifying glasses great for reading small print (think menus and the check) in dark restaurants. Pocket 3X strength magnifying-glass takes up little space, is light weight, not pricey (around $10 at Barnes & Noble), remains lit without having to keep a finger on any button.  Amazon”s Lightwedge magnifier gets same rating, looks similar.Also check out the 5X strength ($9.99) from another mfg. Note: This guide for buying magnifying glasses for those with low vision can be helpful.
• White dishes make it easier for macular-vision affected people to distinguish their food on a plate, for example. Read: Contrast makes the difference
