TESTIMONIALS

“I find that this pair is quite comfortable on the eyes. I wore it for a little over 8 hours and it didn’t irritate my eyes.”

- LotsOfGirlStuff -

“Executive Optical is my family’s go-to place for ten years now, where I got my first glasses and my first contact lenses”

- Bookishmouie -

“Got my Hello Kitty eyeglasses from Executive Optical in SM Masinag. I used to switch from one optical shop to another but eversince I tried the services of Executive Optical last 2011, I only buy my contact lens, solutions and eyeglasses from them. I like that they have an online database system of my record and of their inventory. Very efficient. :D

“The EO doctors were friendly, the staff even. The entire package costs me around less than Php5000.00 only! I think it’s a good deal, I had an eye protector, graded lenses and a shade rolled in one plus the other free stuff that comes with it.”

“Super comfortable po nung lens, less hassle kesa naka eye glasses :)

- Rommel -

“It was the first time I went to EO for my eyeglasses. Staffs are friendly and very accomodating. I’m having a hard time to look for the glasses that suits me. But then, a girl staff gave me this one and it’s just perfect. “Malinaw na ang lahat ngayon.” Thank you! :)

- Jeff -

“What I like about EO is that, it offers affordable eyewear without compromising style and services, I really like the frames. As a style blogger, I always choose fashionable glasses. I also love how fast I got my eyewear. There you have it. Thanks EO :)

“My experience using my contact lens from EO, it was so great because I feel so stunning with my slate gray and sandal wood touch. Not just having the gorgeous and stunning part but the vision was really great. EO is one of the best optical clinic here in the phil.”

- Nicole -

“Lightweight eyewear and welcoming staff. Glorietta branch”

- Shaira -

“I love them! I do makeup tutorials and post it on my youtube channel and facebook page. I wore my contact lenses in all of my videos, since I do not have a clear vision. I dont only have comments about my makeup but a lot of people were asking me where I bought my contact lense and what shade/color I was wearing. Even my friends, they would always ask the same question whenever I hang out with them. I always get compliments!”

- Crisha -

“From 1-10, I’d rate EO eyewear and store: a perfect 10. Among all the eyewear store I’ve canvassed a few months ago, it was only EO store that gave me what I needed  and wanted: stylish, durable, and affordable eyewear. Furthermore, EO Centrio branch’s customer service is excellent. When I arrived in the store, I was warmly attended by the optometrist. When I got the EO eyewear, I loved it so much and I have been recommending Executive Optical to my friends.”
