Is finding a phoropter machine difficult for you? Not at all! But, finding a top-notch manual phoropter is very much meticulous work. However, here we have listed six of the features of an ideal manual phoropter machine you must look for.
One: Faster PD adjustments
PD adjustment is the first factor you must look for in the phoropter machine.lt must offer a sufficient range of adjustments with rapid movements to save time. The higher the PD adjustments with one rotation, the faster it is!
Two: Protection mechanism from dust particles
All your medical equipment is prone to dust. Whether you have a manual phoropter or a digital refractor, dust can enter both. A good question to answer. Obviously, it damages all the equipment. Especially the inner parts of your optical devices get messy and lose performance after some time, you might even feel your device is not working as per expectations
Any solution? Yes, there is! Your manual phoropter machine must have a protection mechanism already installed. For example, dustproof glasses or dust cover keep dust particles away. So, manually review whether your refractor has a dustproof mechanism or not it is not, there is a lot of trouble for you.
There: Distance between Cross-cylinder and Prism Unit
The cross-cylinder is one of the most important components of a manual phoropter. You know. why? Because astigmatism is a complex refractive disorder, and it helps us to discern it effectively
In a manual phoropter machine, there is a distance between the prism unit and the cross-cylinder prism unit. What if you cannot pass the finger between them both? Don't you think it will be difficult to adjust the cross-cylinder range and prism range?
Four: Locking screw diameter for easy and faster moments
Who wants to waste time? Especially when there is a rush of patients at your optical center, no doctor would like to expend time setting up different components. So, the faster the adjustments are, the better the manual phoropter is.
What helps in faster adjustments? Simply put quick movements of lenses and cross-cylinder. What helps in doing it? Locking screw! You might come across a variety of phoropter machines some of them would be better in all the above steps but fail in locking screw diameter. lt will consume more time to adjust. So, your precious time will be wasted!
Five: Quality of components
Quality, quality, and solely quality! it is something you must never compromise on. No matter whether the price is fair, focus on quality components. When going for a China supplier, check whether all the parts of the phoropter procure ultimate quality.
You might wonder why so much focus is on quality, right? Here is why:
- Quality components let the phoropter work efficiently
- No interruptions or errors are there when you have a quality manual phoropter.
- Your manual phoropter will work for years without a decrease in performance
- It will save the cost of buying multiple instruments after some time
Six: Pricing
Price is an important factor. When you have a low budget, you need to find a cost-effective option. Remember, never compromise on quality for the sake of price. A good technique is to assess the quality and determine cost. Keep a balance between both of them. here in Hongdee, we offer manual phoropters machines with different levels of quality and pricing as below:
| Model | Vista | Vista Standard | Vista Regular | Vista Basic |
| Pictures |  |

From the appearance, they look very similar, right? it is very hard for you to differentiate which one is good. So when you are offered a very lower pricing, give it further thought. Do not rush to make the decision, and think about what we have mentioned earlier. Each dollar difference will make a big difference in terms of overall quality and reliability.
THERE ARE NUMEROUS CHINA SUPPLIERS OUTTHEREBUT. REMEMBER TO BE SELECTIVE ABOUT YOUR CHOICES. COMPARE DIFFERENT ASPECTS OF MANUAL PHOROPTERS AND DECIDE ON THE BEST ONE.
Our manual phoropter machine -VISTA is a better choice. Do you know, why? Because it has eight following advantages.
1. Greater PD adjustment range
Vista provides a wider range from 48 to 80mm while other phoropter machines provide 48 to 75mm.
2. Faster PD adjustment
A single rotation for 6mm makes faster PD adjustments. Other phoropters allow 2mm with a single rotation.
3. Distance between prism unit and cross-cylinder
You can slip your finger in between the prism unit and the cross-cylinder. This increases accuracy while rotating the cross-cylinder.
4. Dustproof mechanism
Dustproof glass is available to keep dust away. Most manual phoropters don't have this feature.
5. Astigmatic axis measurements
Vista has no deviations in the astigmatic axis measurements while others might have.
6. Locking screw diameter
Greater diameter for locking screw up to 16mm. Other competitors have a 7mm diameter locking screw.
7. Anti-reflection mechanism
The inner hole is threaded to prevent reflection. This upgrades the accuracy.
8. Lens rotary plate and rare shell gear
Copper plates and gears make Vista durable. Most competitors use plastic plates and gears.
